1.2. General information

By purchasing this system you have acquired a modern and effi cient heating system. Ongoing qua-lity controls and improvements as well as functional checks at the plant guarantee you technically perfect equipment.

Please read through this documentation carefully. It contains important information for correct installation and safe and economical operation of the system.

1.3. Safety Instruct ions

Installation and maintenance work can be hazardous due to high system pressure, high temperatures and live parts and, as such, it should only be conducted by specialist staff.

Heat pumps may only be installed by competent spe-cialist staff and commissioned by a customer service company trained to do so by IDM-Energiesysteme GmbH.

When working on the heat pump the system must be deactivated and secured against reactivation.

In addition, all safety instructions in the relevant do-cumentation, stickers on the heat pump itself and all other applicable safety regulations must be observed.

1.4. Transpor t

During transport, the heat pump must never be in-clined more than 30°. The heat pump must not be transported on its connection fi ttings! Do not remove the transport packaging until the heat pump arrives at its installation location.Noise emission

1.5. Noise emission

TERRA SW Max heat pumps are very quiet in ope-ration thanks to their design. It is however important that the site of the heater is situated as far as possible from noise-sensitive buildings or living areas. A noise-insulating door should be fi tted.

1.6. Construct ion dr ying and screed heat ing

The heat pump is not designed for the increased heat requirements when drying out construction work or heating plaster or screed. This must be covered by equipment to be provided by the customer if required.

1.7. Ser vic ing and Maintenance

Regular maintenance as well as checking and servi-cing of all system components guarantee its safe and economical operation in the long term. To achieve this, we recommend a maintenance contract with the relevant customer service company.

1.8. Cleaning

If necessary, the TERRA Sw Max heat pump can be cleaned with a damp cloth. The use of cleaning agents is not recommended.

1.9. Instal l ing addit ional components

The installation of additional components which have not been tested with the equipment may impair function. No liability is accepted and the guarantee becomes void in the event of damage caused by this.Installation room

General instructions for operating the heat pump.

Important information for installing and operating the heat pump. It is imperative that this is observed!

General information for installing the heat pump.

Space for customer service hotline:

Heat pumps are electrical devices ma-nufactured from high quality materials that should not be disposed of as normal household waste, but disposed of pro-perly in accordance with the provisions stipulated by local authorities.

Besides the penalties issued for offen-ders, improper disposal can also result in environmental damage and health problems.

- The Terra SW Max heat pump must be installed a frost-protected room! (The room temperature must be between 5 °C and 35°C!

- To minimize vibrations and noises, the heatpump must be isolate from the building structure. Basically, the setting up of the heat pump on lightweight design ceilings must be avoided. In case of a fl oating fl oor screed the screed and the sound damping around the heat pump have to be omitted.

- Heat pumps should not be installed in wet roomsor in potentially dust or explosion-endangered rooms.

- Gas from refrigerants in plant rooms must not escape into vicinal rooms, stair rooms, courtyardswalks or into the drainage system of the building.The gas has to be channelled off safely.

- In case of danger, the plant room has to be evacua-ted immediately.

- In case a natural ventilation is not possible, a mecha-nical ventilation has to be provided. A mechanical ventilation has to be equipped with an independent emergency control outside of the machine room near the door.

- Heat pumps should not be installed in rooms with high electromagentic infl uences from other installa-tions.

- -- If the minimum size of the installation room falls below the required value, the room must be designe-das an machine room according to EN 378.

When installing the heat pump, observe all applicable national and international installation, accident prevention and safe-ty regulations for the installation of piping

systems and electrical components and devices, as well as the information included in this installation guide.

These include:

- the generally accepted accident prevention and safety regulations

- the directives for environmental protection - the regulations of the Employer's Liability Insurance Association

- the applicable laws, standards, guidelines and re-gulations, e.g. DIN, EN, DVGW, VDI and VDE

- directives of the local utility companies.

2. Description

2.1. Descr ipt ion

Heat pump for indoor installation with two effi cient, suction gas-cooled scroll compressors with generous-ly dimensioned stainless steel plate heat exchangers as evaporators, condenser and HGL exchanger (for HGL type), two separate refrigeration lines each with fi lter dryer, collector, inspection glass, thermostatic expansion valve, for redundant operation (this makes it possible to continue running the second unit in case of a malfunction of the refrigeration line) built on a stable base frame made of aluminium sections with corner connectors and insulated with heat and noise insulating covers.The heat pump also contains an electrical panel with the Navigator Control and with all the switching and safety mechanisms built-in.

The heat pump uses a compact design. The heat pump is fi lled with refrigerant and has been checked to ensure functionality. Suitable for brine and ground-water operations.

A 4-way switching valve is built into both cooling cir-cuits on the Terra SW Max heat pump with process reversal (P) for cooling operation.

2.2. Appl icat ion range

For monovalent heating of large buildings with geo-thermal heat utilisation. The building should be fi tted with a low temperature heating system (e.g. under-fl oor heating, wall heating, low temperature radiator heating).

TERRA SW Max heat pumps work with the safety refrigerants R 407 C or R 134 a which, when properly installed and commissioned, circulate in a closed circuit and therefore have virtually no environmental impact..

2.3. Scope of del iver y

Equipment included: Heat pump in compact designfor interior installation, with two effi cient hermetic scroll compressor, generously sized copper solderedspecial plate heat exchangers as evaporator andcondenser with insulation, starting current limiter,pressure controller for high and low pressure monito-ring, two separate cold circuits each with fi lter dryer,collector, inspection glass, thermostatic expansionvalve, for redundant operation; this means that inthe event of a fault in the cold circuit, the second unitcontinues to operate.It is constructed on a stable base frame with casingframe made from aluminium profi les with corner connectors, noise and heat insulating plate covering.The TERRA SW Max is also available in a version with process reversal. For cooling operation (reversi-ble mode), a four-way changeover valve is integratedinto both cooling circuits for a process changeover. The heat pump is actuated via the Navigator cont-roller.

2.4. Accessories

- Flexible connection hoses 2“ - Flexible connection hose 5/4“ - Charging pump group A-Label - Flow control switch, for monitoring the fl ow on the groundwater side

- Flow sensor for 2nd heating circuit - Expansion module, internal, for two heating circuits incl. sensors

- Heating circuit control module, external, for three additional mixer heating circuits

- Offset roomstat for a heating circuit to NAVIGATOR - EIB-KNX module - Pressure controller for brine systems - Flow meter 5/4“ for HGL fl ow - Flow meter with fl ange for heat pump fl ow - Spirovent silt and air trap for installation in the re-turn line or HGL fl ow line

2.7. Operat ing l imits

TERRA SW Max heat pumps may only be used with heat conducting media, brine or ground water. Other heat conducting media are not allowed.

Furthermore, heating of liquids other than heating water is not permitted (heating water quality see Chapter "Assembly Heating Side").

By defi nition, heat pumps are subject to pressure or temperature-dependent operating limits (see sketch).

The operation of the TERRA heat pump outside these operating limits is not allowed.

Note:

The following safety mechanisms are provided for the safety of the heat pump against potential malfunc-tions:

- Combined high and low pressure cartridge switch with automatic locking or unlocking by switching the system off and on (after 3 malfunctions within 24 hours).

- Flow maximum temperature limit with automatic reset via the Navigator Control.

- Start-up current limiter with rotating fi eld monitoring, motor current monitoring and phase monitoring for the compressor.

- Internal winding protection in the compressor

3.1. Instal lat ion

The installation of the TERRA SW Max heat pump must be undertaken in a frost-proof room by an ap-proved specialist company. The room temperature must be between 5°C and 35°C.

With regard to the installation room requirements please observe EN 378 Part 1 and 2.

The installation in wet rooms, in rooms at risk from dust or explosions is not permitted.

In order to avoid structure-borne sound transmissions, the TERRA SW Max heat pump must be installed on a horizontal, level and weight-bearing surface (con-crete plate or similar). In the case of fl oating screed, the screed and the impact sound insulation must be recessed around the heat pump to ensure low noise levels when the heat pump is operating.

The applicable laws, regulations and standards must be observed, in particular EN 378 Part 1 and 2 as well as BGV D4.

To avoid noise transmission via the piping, it is advisa-ble to fi t suitable compensators in the heat pump fl ow and return and HGL pipes and in the brine inlets and outlets or groundwater inlets and outlets, or to use connecting hoses. Avoid kinks in connecting hoses!

Observe the clearances at the sides and rear as detailed in the sketch to support assembly and maintenance work.

TERRA SW Max HGL with Hygienik and heating buffer accumulator (N_1.6-0-2-5-2-0)

The Hygienik is only used to prepare tap water and during the priority charging procedure is charged with a speed-controlled charging pump at the set HGL temperature.

The heating is fed via an additional heating buffer. During heating operation the top area of the Hygienik is recharged at the set HGL temperature.

A cascade system is also possible using this layout.

If it is a cascade system, a non-return valve must be used for the respective heat generator.

When using fl ow meters to measure the heat volume, the sensor B38 must be fi tted in the immersi-on sleeve provided in the heat pump return directly on the heat pump (see installation instructions fl ow meter).

To allow the charging temperature to be kept constant in case of priority charging, the charging pump M 21 must be an high-effi ciency pump with 0-10V control input.

Another way to implement a speed control in priority mode is that two pumps are used. A stan-dard pump for heating (M21.1) and a smaller charge pump (1-phase) for the priority mode. See „4.14 Speed controlled charging pump“ page 26.

TERRA SW Max with Hygienik and heating buffer accumulator (N_2.6-0-2-5-2-0)

In the hydraulic diagram shown below, the Hygienik is used exclusively for tapwater preparation. The Hygienik is loaded via the priority valve.

The heating is fed via an additional heating buffer. The heating can be designed as a pump or mixer cir-cuit, in which case the installation of a heating mixer is recommended.

When using a fl ow meter to measure the heat volume, sensor B38 must be fi tted in the immersion pipe provided for the heat pump return directly in the heat pump.

The Hygienik is only used for hot water preparation and is charged by a separate high temperature heat pump.

In this layout the TERRA SW Max is only used to charge the heating system. The heating is fed via an additional heating buffer.

The heating circuits can be designed as pump or mi-xer circuits, in which case the installation of a heating mixer is recommended.

TERRA SW Max with heating buffer and TERRA SW H with Hygienik for washwater preparation (N_2.6-2-2-5-2-0)

This layout is used for larger systems such as in e.g. appartment blocks.

The advantage of separate washwater treatment and heating system charging is that relatively constant operating conditions apply for both heat pumps in-dependently of one another. That is, the TERRA SW Max always has a low fl ow temperature and thus a good COP. The TERRA SW Max H with the high temperature refrigerant R134a still operates at a fairly favourable operating point despite the higher fl ow temperatures for washwater charging.

When using a fl ow meter to measure the heat volume, sensor B38 must be fi tted in the immersion pipe provided for the heat pump return directly in the heat pump.

Heat pump TERRA SW Max with process reversal (N_1.6-0-2-5+6-2-3)

Process reversal is only supported for heat pumps with an integrated process reversal function.

In the layout shown below, heating circuits HK (A) and HK (B) can be switched between heating and cooling.

To switch to cooling operation using process rever-sal, cooling valves M61 and M62 must be installed additionally.

Use of a room moisture sensor

When using a moisture sensor in combination with a roomstat the moisture sensor must be placed in a reference room for humidty. The Navigator Control uses the reference humidity and the individual room temperatures to calculate the theoretical dewpoint for the individual heating circuits.

To avoid moisture damage to the building in cooling operations, you must fi t a mois-ture sensor in combination with roomstats for each cooling circuit. Alternatively, you

can connect a dewpoint switch for dewpoint moni-toring to the control unit.

When using a moisture sensor in combi-nation with roomstats, the control wheel on the roomstat must be in central posi-tion during cooling operation. Changing

the roomstat setting will falsify the calculated dewpoint for the heating circuit in question!

3.2. Instal lat ion heat ing s ide

The relevant laws, regulations and standards for ma-chine room piping and for heat pump systems must also be observed.

- It is essential that a silt trap is fi tted in the heating return pipe upstream of the heat pump.

- Safety devices and expansion devices for closed heating systems according to EN 12828 must be fi tted.

- Pipe dimensions must be appropriate for required fl ow volumes (see Chapter, Technical Data).

- The charging pump must be fi tted in the Hygienik/buffer return line to the heat pump (see sketch below). For basic type and HGL type, you must provide the charging pump; it is available as an accessory.

- Connection hoses for the heat pump fl ow and re-turn, as well as for the HGL connection are availa-ble as options and must be installed. Connecting hoses can be trimmed to the required length, but not shorter than 60 cm. In addition, avoid kinks in connecting hoses.

- Venting options should be fi tted at the highest points of the connection lines, and draining options at the lowest points.

- To avoid heat loss connection lines should be insu-lated using suitable material.

Oxygen diffusion

With plastic pipe underfl oor heating or open heating systems which are not diffusion-tight, corrosion may occur on steel parts when using steel pipes, steel radiators or storage tanks due to oxygen diffusion.

Corrosion products can be deposited in the conden-ser and may cause heating losses in the heat pump or high-pressure faults.

For this reason, open heating systems or steel pipe installations in combination with plastic pipe under-fl oor heating which is not diffusion-tight should be avoided.

Heating water quality

Depending on the quality of the heating water, lime scale may occur (adherent coating primarily consis-ting of calcium carbonate) on heat exchanger sur-faces, i.e. with a high proportion of calcium hydrogen carbonate there is an increased risk of lime scale forming.

For fi lling heating systems, very clear guidelines ap-ply relating to the heating water quality. Specifi cally, European standard EN 12 828, ÖNORM H 5195 and in particular VDI Guideline no. 2034-1 must be obser-ved and represent the current state of art.

The pH value of the heating water should also be checked; this should be between 8 and 9.5.Air separator

Dirt separator Charging pump available as an accessory(standard pump or A-label pump)

In heat pumps with process reversal is already compulsory to install a fl ow meter on heating site now!For brine machines, the fl ow meter must be connect on the digital input “Error heat source circuit” (see wiring diagram). For groundwater machines, the fl ow meter must be connected serial to the groundwater fl ow meter.

4. Electrical installation

4.1. Power supply

Electrical connection must be registered with the relevant power supply company.

The required series-connected fuse for the primary circuit can be calculated from the technical data (starting current compressor), charging pump power consumption and the power consumption of the on-site brine/ground water pumps installed, as well as any circulation pump used.

It is essential that a “slow-blow” design is used (“C” or "K" characteristic). The relevant cable cross section must be determined by the electrician.

All systems are fi tted with a start-up current limiter that also monitors the power consumption and the phasing.

A power protection switch is already fi tted for the brine or ground water pump. In particular it is recom-mended to install a suitable motor protection switch in the supply line to the brine or ground water pump and charging pump.

The heat pump is operated via the NAVIGATOR® Control.

Depending on system design, appropriate sensors may be required; see the wiring diagram for more information.

For reliable operation of the heat pump, the voltage in the mains network must be within specifi c tolerance limits, between 360 and 430 V (check with your local utility company if necessary).

Primary current connec-tion:3 x 400 V/50 Hz

Brine / groundwater pump control 3 x 400 V / 50 Hz

Charging pump control 3 x 400 V / 50 Hz

Recommendation:install a suitable motor protection switch

4.2. Removing the covers

Prior to the electrical connection, the covers must be removed. To do so, remove the fastening screws and set the main switch to 0 position (OFF). After having done this the connection terminals are freely acces-sible. The connection for the control and primary circuit is designed separately.

You must not connect the system to the mains and put it into operation until the entire heating system has been fi lled and bled, otherwise the circulating pumps may run dry.

Before removing the left cover, set the main switch to 0 position (OFF) to allow the cover to be removed.

- Before removing the covers switch off the power supply to the system and secure it against reacti-vation.

- Before starting the system, check the pumps for smooth running.

- Before commissioning the system, tighten the terminals.

4.3. Power Supply Connect ion

The power supply connection of the primary circuit takes places directly on the main switch Q1 as shown in the following fi gure and in the wiring diagram.

The power supply for control voltage is directly to ter-minal X2 on the terminal rail as shown in the following fi gure and in the wiring diagram. You must not patch the control voltage from the mains voltage.

Control voltage connection: 1 x 230 V/50 Hz Main voltage connection: 3 x 400 V/50 Hz

The supply lines must have the relevant thickness. For more information, see technical data point on page - max. power consumption.

All other connections must be established directly on the microprocessor control board or are already factory set (see the following pages).

The electrical wiring of additional devices on the output terminals on the control board must be done using fl exible cables 1.5 mm². End sleeves must be used for the cabling.

4.4. Connect ing the heat source pump

The line cross section for the connection of the brine circuit or ground water pump must be sized according to technical data.

It is possible to connect both single-phase and three-phase brine circuit or ground water pumps.

Refer to the wiring diagram for the system for connec-ting the brine or groundwater circuit pump.

4.5. EMC compatibi l i ty

Please take note of the following with regard to this is-sue: Electro-Magnetic Compatibility (EMC) demands additional work and expertise from all manufacturers and operators of modern electrical technology and electronics year on year.

As the number of electronic devices in use increases continually, the number of potential sources of inter-ference also increases. A combination of cables from the power supply company, transmission stations and other communications devices generate an invisible “electrosmog".

This interference affects all systems, both biological (us as living beings) as well as technical electrical systems. They generate undesirable fault currents which can have different effects.

The effects on biological systems can only be guessed at currently, but the effects on technical electrical systems are measurable, and in the worst case, visible as well.

The faults can have different effects:

- Short-term measurement faults - Permanent measurement faults - Short-term interruption in data connections - Permanent interruption in data connections - Data losses - Damage to equipment

Potential sources of interference are essentially all technical electrical systems, e.g. contactor coils, electric motors, transmitters, mains and high-voltage lines, etc., and the equipment can be affected via different coupling routes (galvanic, inductive, capaci-tive, via radiation).

As far as we are concerned, everything has been done to protect the Navigator Control from interfe-rence (hardware design etc.). It is the responsibility of the electrician in particular to avoid any possible cou-pling routes when setting up the electrical installation.

Motor protection for brine/ground wa-ter pump must be effected by owner/operator.

4.6. Connect ion Diagram Electr ical Compo-nents

The central unit of the control system is located under the cover. Two mainboards are fi tted with mainboard A1 (central unit 1) acting as the Master and mainboard A7 (central unit 2) as the Slave. The two mainboards A1 and A7 are connected via a CAN Bus. All connec-tions on the central unit are designed to be pluggable.

The control unit located in the control panel for the Navigator Control is connected to the central unit via a patch cable with a length of approx. 1.5m.

Additional modules such as the (internal) expansion module for another two heating circuits, as well as a GSM Module, can be retrofi tted as shown in the diagram below. The (external) extension module for 3 additional heating circuits can only be used if you are not implementing cascade control.

The electrical assemblies (control unit, expansion modules, etc.) are always con-nected to mainboard A1 (central unit 1).

4.7. Input assignments on the central uni t

Please refer to the system wiring diagram for the central unit input wiring layout.

4.7.1. Sensor design

Sensor lines have a cable cross section of 0.75 mm² as standard.

The sensor positions are shown in the relevant in-stallation diagram. Reliable operation can only be ensured by correct positioning and good heat transfer (heat conducting paste).

If necessary, the sensors can be extended using a suitable cable. Refer to the wiring diagram for the sensor extension line cross-section. Make sure the connection is clean and corrosion-free.

4.7.2. Sensor equipment

The following sensors are contained in the scope of delivery or are already installed and, in any case, required:

- Outside sensor, B32 - Heat pump fl ow sensor, B 33 - Heating buffer sensor (return line sensor heat pump), B39

- Heat source outlet sensor, B36 - Flow sensor heating circuit A, B51 - HGL fl ow sensor B35 (only for the HGL design) - Hygienik sensor B41 (only for HGL design)

(All other sensors are optional depending on the sys-tem equipment).

4.7.3. F low temperature sensor

The fl ow temperature sensors for the heating cir-cuits used are required in every case. They must be connected on the corresponding fl ow lines and in accordance with the connection diagram.

The fl ow sensors for the heating circuits C-G are connected on the respective heating circuit expansi-on module. (see the installation instructions for the expansion module for more information)

4.8. Impulse Inputs

When using fl ow meters in the heat pump fl ow (volu-me fl ow meters) to measure the heat volume they are connected as indicated in the wiring diagram.

Refer to the installation guide for the fl ow meter for the installation and confi guration at the control unit!

A standard set of sensors is supplied with each heat pump and provided in the elec-trics sump of the heat pump.

Sensor lines should be run separately from mains cables, (see EMC issue!).

When attaching the inputs, check which mainboard (central unit A1 or A7) the components must be attached to.

If you are using zone valves, you can generate composite signal from all zone valves to be able to switch the heating

and cooling circuit on and off with the thermostat function.

4.9. Output layouts

Max. output loads:

- Triacs (connections 10 - 12): max. 3.15 A (max. individual triac load: 1A)

- Relay (terminals 20 to 39): max. 6.3 A

Please refer to the wiring diagram for the system for analog, digital and triac output assignments on the central unit.

4.10. Connect ion of the mixers

The mixers use three-pin connections according to the enclosed wiring diagram.

Mixer open = brownMixer closed=black

4.11. System Ear thing

When the protective conductor is connected correctly, the electrical panel and the heat pump casing are earthed.

After maintenance work, ensure that the equipotential bonding is properly re-established.

4.12. Maximum restr ic t ion for under f loor heat ing

With underfl oor heating circuits, an additional clip-on thermostat must be fi tted and the relevant heating circuit pump supply switched via it in series.

4.13. Composi te s ignal zone valves

The composite signal zone valve setting generates a request when one of the zone valves is open. The difference to a roomstat function is that, indepen-dently of heating or cooling operations, a request is generated when a zone valve contact is closed.

4.14. Speed control charging pump

To implement speed control, you must use a high-effi ciency pump as the charging pump. The pump speed is controlled via a 0-10V output.

Another way to implement a speed control in priority mode is that two pumps are used. A standard pump for heating and a smaller charge pump (1-phase) for the priority mode. For this confi guration an additio-nal auxiliary switch in the HGL mixer motor (art.no. 540606) has to be used for the HGL heat pumps. The auxiliary switch changeover between the contactor Q13 for the standard loading pump and the smaller loading pump (-phase). In this way the speed control

When attaching the outputs, check which mainboard (central unit A1 or A7) the components must be attached to.

You cannot implement speed control of the standard charging pump supplied via the triac output, as this exceeds the output load limit of the triac output.

of the smaller loading pump during the priority mode via the triac output is possible. For TERRA SW Max heat pumps the changeover can be generated from an additional relay by the output of the priority valve.

4.15. Addit ional modules for Navigator Control

To extend the Navigator Control functionality, you can purchase a number of additional modules, which are connected to the mainboard. The following are examples of additional modules:

4.15.1. Heat ing c ircui t expansion module internal

The internal expansion module permits the control of two additional heating and/or cooling circuits via the Navigator control. Two mixers and the relevant fl ow sensors, the offset roomstat and the heating circuit pump can be directly connected on the expansion PCB.

4.15.2. Heat ing c ircui t expansion module external

The internal expansion module permits the control of three additional heating and/or cooling circuits via the Navigator control. The heating circuit control module, external allows three mixer circuits to be connected to the respective heating circuit pumps, fl ow sensors and room units. Communication with the Navigator Control is effected via a CAN bus connection. This allows the Navigator controller to be placed up to 300 m away. An external heating circuit expansion module cannot be used with cascade systems.

4.15.3. EIB/KNX module

The EIB-KNX module can be used to connect EIB-KNX devices to the heat pump. The resulting EIB-KNX-compliant heat pump can communicate with other EIB-KNX devices, such as sensors and actua-tors, via this module. This enables data such as tem-perature, operating conditions, etc. to be exchanged and processed between the devices.

With the Navigator a MODBUS TCP can be realized. For this a connection to a LAN network is required.

4.17. Cascade control

The Navigator Control supports cascade control. In doing so, the Navigator Control supports demand-driven, gradual actuation of up to 5 heat pumps. The heat pumps are connected via a CAN bus. Up to 4 heating circuits per heat pump and a combination of HGL and basic machines with/without process rever-sal are possible.

5.2.1. Descr ipt ion

These systems use plastic pipes laid in the ground for heat extraction. Multiple pipework circuits may be required depending on the heat pump size. The brine medium circulates through these pipes. The heat exchange between the brine medium and the refrige-rant takes place in the evaporator set (stainless steel plate heat exchanger).

5.2.2. Notes

- Flexible hoses or compensators are required between the brine distributor and the heat pump, directly at the heat sources, fl ow and return con-nections on the heat pump to avoid structure borne noise.

- Only antifreeze approved by IDM Energiesysteme GmbH may be used (propyleneglycol/water mix 30%).

- Use a brine medium mixing ratio for up to -15°C (= 30% antifreeze). If too much antifreeze is added, the specifi c heat content of the brine medium drops.

- Brine circuit lines must be provided with steam diffusion-tight insulation in the event of the forma-tion of condensation and the accumulation of ice (e.g. Armafl ex).

- Brine circuit pump and brine circuit expansion ves-sel must be positioned on the heat pump inlet side (warm side).

- The brine circuit expansion vessel must be connec-ted from the brine line upwards.

- When fi lling the brine circuit with antifreeze mix, the expansion vessel must be fi lled (due to a reduction in volume through cooling during operation).

- The installation should take place several months before the heating period. Corresponding prepara-tion times need to be taken into account during the overall planning process.

- Plants with deep-growing root structures must be avoided in all cases.

- Rainwater must not be diverted using drainage as it is required to regenerate the ground.

- When back-fi lling, a signal band of approx. 0.5 m above the pipeline should be laid to avoid subse-quent damage.

- In the case of surface collectors, the overlying sur-face must not be closed off (e.g. by asphalting).

- Within the area of junction ofthe collector tubes, the tubes on a length of 2m should be insulated.

- Do not use zinc-plated pipes. - Keep a minimum distance 1 m between the lines and water/drain pipes as well as brickwork.

- Wall ducts must be insulated and watertight. - Draw up a laying plan and take photos. - The distributor connection can also be located out-doors in a pit.

In many countries, geothermal utilisation must be approved by the water autho-rities. Apply for planning permission in good time.

The fl at collector dimensions must be carefully calculated by the planning engi-neer. The values specifi ed in the technical data, such as "Number of brine circuits",

"Overall piping length", "Brine fi lling capacity", should be regarded as guidelines only; they do not replace an expert assessment and specifi cation of requirements. Additionally, all heat source side components up to the heat pump coupling must be provided on site. In doing so, always observe local regulations and laws.

5.3. Br ine depth probe


This system uses soil probes for heat absorption from the ground. They are made of plastic piping with a special plastic head. This evaporation system requi-res the smallest base area for the soil evaporators. The bore diameter is 125 mm, the bore depth and probe length depend on the heat pump size. The bri-ne medium circulates through the plastic pipes. The heat exchange between the brine medium and the refrigerant takes place in the evaporator set (stainless steel plate heat exchanger).

For the connection of the brine circuit it is required:Brass distributor with shut-off valve, safety valve, manometer, expansion tank, thermometer and brine circuit pump.

The delivered fl exible connection pipes must be in-stalled to avoid sound transmission. The connection pipes between distributor and heat pump must be allocated by client. It is not allowed to use galvanized pipes!

The depth probe dimensions must be carefully calculated by the planning engineer or a geologist. Drilling may be performed only by a licensed company.

5.3.2. Notes

- Only antifreeze approved by IDM Energiesysteme GmbH may be used (propyleneglycol/water mix 30%).

- Brine circuit lines must be provided with steam diffusion-tight insulation in the event of the forma-tion of condensation and the accumulation of ice (e.g. Armafl ex).

- Position the brine circulating pump and brine cir-cuit expansion vessel on the heat pump inlet side (warm side).

- Connect the brine circuit expansion vessel in up-ward direction from the brine line.

- When fi lling the brine circuit with antifreeze mix, the expansion vessel must be fi lled (due to a reduction in volume through cooling during operation).

5.3.3. Dimensioning of the depth probes

Is the use of geothermal heat by probes in the short-list, is to obtain information about the soil through a geological report. You‘ll fi nd further details about related requirements, the expected soil structure, as well as notes about the maximum abstraction capacity.

5.4. Groundwater system


This system uses groundwater as a source of heat. When using groundwater, the water is pumped out of an intake well, cooled in the evaporator and fed back to the groundwater via an injection well. Make sure that the injection well is located in the ground water direction of fl ow downstream of the intake well and at a distance of at least 15m.

To prevent malfunctions you must fi t and connect a minimum temperature limiter and a fl ow switch.

5.4.2. Notes

- To prevent corrosion and frost damage to the plate heat exchanger in the heat pump, IDM- Energiesys-teme mandates the use of a safety heat exchanger for groundwater systems.

- In the event of above average levels of particulate matter in the well water (sand, sludge), you must use sedimentation basins to prevent blocking the evaporator or safety heat exchanger.

- Ensure that the inlet and outlet lines are laid as frost-proof, with an incline to the well.

- The lines in the house must be insulated against the formation of condensation.

- From the intake well up to the heat pump, a protec-tion pipe is also required with an electric line for the well pump.

- Ensure that the well cover is light and airtight to prevent the formation of algae and sludge accumu-lation.

- A submersible pump is recommended as the well pump.

- After being set up, the well should be rinsed for approx. 48 hours.

5.4.3. Appl icat ion range

Water inlet temperature: at least + 7 °C (Danger of freezing!)

Ground water quality:

The following values must be observed:

- ph value: 6.5 - 9 - Chloride: < 100 mg/kg - Sulphates: < 50 mg/kg - Nitrates: < 100 mg/kg - Manganese: < 0.1 mg/kg* - Free carbon dioxide: < 20 mg/kg - Ammonia: < 2 mg/kg - Iron: < 0.2 mg/kg* - Free chloride: < 0.5 mg/kg - Electrical conductivity: > 50μ/cm and <

600μ/cm - Oxygen < 2mg/kg*

* Exceeding these limit values can cause silting of the evaporator and inlet lines, as well as iron ocher build-up in the injection well.

In order to verify the water temperature, and the water volume and quality, a test well and a pump trial is recommended over 48 hours. The test should preferably be carried out at the end of February.

Apart from the safety heat exchanger set (accessory), all heat source side components up to the heat pump connection must be provided and effected on site. Observe local regulations and laws during planning. The minimal groundwater circulation volume must be permanently fed to the heat pump connector by the well system.

5.4.5. Safety heat exchanger for groundwa-ter systems

This means that the ground water circuit of the heat pump is uncoupled via a safety heat exchanger through a brine circuit. Possible damage in the ground water circuit or in the safety heat exchanger therefore does not cause any subsequent damage to the heat pump.

Thsafety heat exchanger must be integrated with the groundwater circuit as shown in the previous installa-tion diagram.

To prevent corrosion and frost damage to the plate heat exchanger in the heat pump, IDM- Energiesysteme mandates the use of a safety heat exchanger for groundwater systems.

You must use an antifreeze mix with 25% Propyleneglycol in the safety brine circuit. Only use antifreeze approved by IDM Energiesysteme GmbH.

5.4.6. Groundwater f low meter

For simple monitoring of the necessary groundwater quantity, we recommend using a fl oat-type fl ow meter. It is available as an accessories.

5.4.7. Groundwater f i l ter

Use a centrifugal trap as the groundwater fi lter, made e.g. by Lakos.

6.1. Commissioning information

Before starting up the TERRA SW Max heat pumps, the heating side and the brine or ground water circuit side must be checked for tightness, rinsed thorough-ly, fi lled and bled carefully.

Commissioning requirements :

- The heat pump may only be commissioned by a customer service engineer specially trained and authorised by IDM-Energiesysteme GmbH!

- Avoid commissioning the heat pump in the cold season (December, January) due to climatic condi-tions (ground temperature). This is especially true if the heat pump is to be used for screed drying.

- The heating and any storage tank must be fi lled and bled.

- In the case of brine circuit heat pumps the brine circuit must be fi lled with antifreeze (-15°C), rinsed and bled.

- The expansion vessel on the brine side must also be fi lled.

- The electrical installation must be completed and fuse-protected in line with legal requirements.

- The heat pump may only be switched on if it is fi lled on the cold side and on the heating side, and if the electrical connections have been checked.

- The heat pump is equipped with a start-up delay. - If the heat pump is to be drained on the heating side for frost protection, the connection hose on the heat pump return must be unfastened.

- In the case of ground water heat pumps, the ground water outlet alarm during start-up must be set in such a way that shutdown is carried out at a water return temperature of 3°C.

6.1.1. Select ion of the Heat Source Pump

After actuation of the main switch on the heat pump, the start-up Wizard is started after selecting the lan-guage. In the start menu of the start-up Wizard, the heat source pump for fl ushing and bleeding the brine or ground water circuit can be selected manually via the Navigator Control.

6.2. Operat ion

The Terra SW Max heat pump is switched on and off automatically via a fully-automated Navigator Control system. For operation and start-up, please refer to the separate operation and start-up instructions.

Annual inspection and maintenance of the system by customer services is recommended, in particular with regard to the preserving warranty claims.

6.3. Malfunct ions

The TERRA SW Max heat pump is fi tted with various safety devices to ensure that no damage can be caused to the equipment in the event of faults.

If under unusual circumstances the heat pump fails to work at any time, check the error message on the Navigator Control display.

For more information, please see the Navigator Con-trol operating instructions.

If an error occurs several times in succes-sion, please contact your IDM Customer Service.
