1.0 HOW THE CALOREX ' SERIES 2 VARIHEAT' SYSTEM WORKS

The Calorex 'SERIES 2 VARIHEAT' range consists of 3 models 570/870/1270.The model number increases in relation to the recirculated air flow, from Model 570 at 1800m³/hto Model 1270 at 3000m³/h.When optional fresh air feature is fitted, all models have the facility to exhaust a percentage ofthe recirculating air and introduce a slightly lesser amount of fresh air.(Slight differential creates a negative pressure on pool hall to localise pool environment andprotect the building fabric).All models are fitted with a fully controlled air heater battery and pool water heat exchanger.These are designed to operate with LPHW at 80°C provided by a standard boiler. Provision ismade for this boiler to be initiated by the 'SERIES 2 VARIHEAT' controller. All models have airand water heat exchangers deriving energy from the refrigeration/dehumidification process.These are also fully controlled with priority given to water.

THE CALOREX SERIES 2 VARIHEAT RANGEFEATURESAll SERIES 2 VARIHEAT models have direct drive main recirculating fans.Models fitted with the optional fresh air feature have motor driven variable louvres on the exhaustand fresh air dampers.The power to each model in the SERIES 2 VARIHEAT range is fed in via a terminal block locatedin the electric box of the unit.CONTROL PANEL. All ModelsThe panel has the following equipment:1. Relative Humidity Controller: with red indicator light below it showing dehumidification takingplace.2. Air Temperature Controller: with red indicator light to show heating taking place.3. Water Temperature Controller: with red indicator light to show heating takingplace.4. Damper Control Switch: (if fitted), enabling damper to be set to automatic operation(normal) or fully closed manually.5. Power Switch: to switch the machine ON and OFF. With the unit switched OFF, onlythe mains indicator light and the clock are energised.6. A time clock to control the "occupied/unoccupied" timings with battery 'back up' andmanual override.7. A row of indicator lights showing:Mains ONAutomatic OperationFaultDefrostBelow the panel in the electrical control box is a manually set thermostat, for setting theunoccupied pool hall air temperature.In the same area are the control circuit fuses and motor protection overloads.

SD092761 ISSUE 30

OPERATIONWhen the SERIES 2 VARIHEAT is connected to the mains supply via an isolator, and theisolator is energised, the MAINS Light on the panel will light indicating mains ON, theclock will commence operating, and the fan will start. The clock has a battery reserve fittedwhich when charged has an operating time of 100 hours so that isolating the SERIES 2VARIHEAT unit for short periods will not change the clock setting.The SERIES 2 VARIHEAT unit is switched on to normal operation by an ON(I)/OFF(0)switch on the control panel.Providing that the controls are set to the correct parameters, nominally 60% RH, 28°C airtemperature and 26°C water temperature and the fresh air switch, if fitted, is set to AUTO,then the machine will operate automatically. The 'unoccupied' temperature is set on thethermostat mounted inside the electrical control panel and will be switched at the time set onthe clock.As the unit operates, the indicator lights positioned below their relative control instrument willindicate the state of the control conditions, with the lights indicating dehumidification, heat toair and heat to water.At the top of the panel are four further lights:Red for Mains ON (showing that the isolator is made and the unit is energised).Amber for Fault (high or low refrigerant pressure trip).Clear for Defrost.Green to indicate automatic operation.

PARAMETER CONTROLLERSEach parameter; Relative Humidity, Water Temp and Air Temp is sensed within the machine andthe signal is taken to the relevant controller.Each temperature controller on the SERIES 2 VARIHEAT has two switching channels:Kl (OUT1) which is set from the front panel K2 (OUT2) which is factory pre-set.Each channel has a switching differential which is also pre-set in the factory. Neither should betampered with.When the re-settable channel Kl (OUT1) is adjusted all other settings and differentials on thatcontroller automatically follow at the correct relationship.For example.If the air temperature is set at 28°C then the following settings follow.LPHW ON 27.7°C LPHW OFF 28.3°DAMPERS OPEN 30.3°C IF FITTED DAMPERS CLOSE 29.7°C.This is given as an example but it is not necessary for the operation of the unit for thesefigures to be known by the customer.

OPERATION

TIMECLOCKThe time clock setting determines the OCCUPIED/UNOCCUPIED periods and is set tomatch the operators' requirements regarding opening and closing times for the pool andpossible times where the pool is covered.There are two settings as mentioned OCCUPIED or daytime, and UNOCCUPIED ornight time (covered).The most obvious action of this change is to lower the pool hall air temperature to adetermined temperature to conserve air heating energy. This lowering of temperature isallowable because of the quiescent, and hopefully covered, condition of the pool. TheUNOCCUPIED pool hall air temperature is controlled by a dedicated thermostat mountedbehind the control panel.

SD092761 ISSUE 30

DAMPER CONTROL SWITCH On the front control panel is a 2 position switch which controls the inlet/exhaust air dampers (if fitted).In OCCUPIED operation AUTO will allow the units control system to drive the damper motors to achieve the optimum condition for operation, but provision is made to manually drive the dampers to MIN .In UNOCCUPIED operation the AUTO setting will drive the dampers to MIN as will the MIN setting.

CONTROLThe unit is automatically controlled by reference to three parameters, each one having adedicated controller mounted in the control panel.

Each temperature controller has one user adjustable set point with a 2nd switch point preset in relation to it, as described above. The user adjustable RH set point controls the ON-OFF point of the dehumidification compressor directly. The user adjustable air temperature set point controls the ON-OFF point for the LPHW heater battery directly, and, indirectly controls the "air conditioning" mode (if fitted) ON-OFF 2°C above the set point.The user adjustable water temperature set point controls the dehumidification driven water heating condenser directly and, indirectly 0.2°C below the set point, controls the LPHW water heater calorifier.

OCCUPIED AND UNOCCUPIED DIFFERENCES.The time clock determines the OCCUPIED and UNOCCUPIED periods according to its setting.The general operational difference is as follows:The time clock has a set of contacts which are energised during occupied periods.These contacts energise in turn the AS2 (air conditioning) contacts on the air temperature thermostat and a relay which, deselects the UNOCCUPIED thermostat, selects the OCCUPIED thermostat, and, selects full auto control for the dampers.In essence the unit operates in all modes in OCCUPIED condition. In UNOCCUPIED condition it operates similarly with the exceptions as follows:a) Pool hall air temperature lowered to the setting of the UNOCCUPIED thermostat.b) Fresh/exhaust air dampers (if fitted) driven to MIN when 2 position switch is set to AUTO.The unit can be manually overridden to occupied via the remote low voltage switch,see circuit diagram page 16.

2.3 PLUMBING

2.3.1) POOL WATERa) The Calorex ‘SERIES 2 VARIHEAT’ must be connected after the filter in the return pipe to the pool. If anexisting heater is being retained, then the ‘SERIES 2 VARIHEAT’ should be connected between the filterand the existing heater (see following schematics).b) Calorex ‘SERIES 2 VARIHEAT’ units have PVC-U stubs 1½” dia for connecting the pool water inlet andoutlet.c) Suitable breakable couplings, isolation, and drain down valves should be installed in the pool water inlet/outlet pipes local to the ‘SERIES 2 VARIEAT’ unit.d) The heat exchanger in the ‘SERIES 2 VARIEAT’ unit will on small pools, take the full flow rate of therecirculation system. On larger pools a bypass or separate auxiliary pump may be necessary. This methodcan also be used to reduce energy consumption, by the installation of a two speed or auxiliary pumpbypassing the main pump/filter to satisfy pool water heating and dehumidification without the need for themain pump to be running. Further savings on both the above methods can be made by utilizing the standardfeature on all ‘SERIES 2 VARIHEAT’ units to control the main or auxiliary pumps (see section 2.4 electricalwiring).e) When the pipe work installation is complete the circulating pump/s should be switched on and thesystem checked for leaks. Also check the filter gauge to see that there is not excessive back pressure.

2.3.2) CONDENSATE DRAINa) The condensate drip tray at the base of the ‘SERIES 2 VARIHEAT’ unit collects the water removed by thedehumidification process. It is therefore necessary to ensure that the ‘SERIES 2 VARIHEAT’ unit is placedon a level plinth so that the condensate can run away and not overflow the edges of the drip tray inside themachine.b) All ‘SERIES 2 VARIHEAT’ units have a ¾” BSPM threaded condensate drain connection. The drain pipeshould be run away with the adequate fall to waste i.e. ½” per foot min. and must incorporate a ‘u’ trap.

2.3.3) L.P.H.W. WATER PLUMBINGa) Calorex ‘SERIES 2 VARIHEAT 570/870’ units have 28mm copper stubs whilst ‘1270’ models have 35mmstubs for connecting (compression or solder) the boiler water flow and return.b) Suitable breakable couplings isolation and drain down valves should be installed in the boiler water flow/return pipes local to the ‘SERIES 2 VARIHEAT’ unit.c) A mixing valve and/or bypass may be required to maintain a minimum boiler return temperature and/orkeep a constant load to the boiler pump. Refer to the boiler manufacturers instructions before designing thepipe work system.d) If boiler and water pump is not controlled by ‘SERIES 2 VARIHEAT’ then a boiler bypass will be required.

2.3.4) IMPORTANT GENERAL POINTSa) Do not route water pipes across service access panels or Air inlet/outlet.b) The water circuits to and from the ‘SERIES 2 VARIHEAT’ units should be capable of maintaining withinthe specified limits the water flow required. (see section 4, Data Sheet)c) All pipe work must be adequately supported with allowance for expansion and contraction especially withregard to the plastic pipe work.d) It is recommended that when installing water systems the last connections to be made should beadjacent to the ‘SERIES 2 VARIHEAT’ unit to avoid undue stresses on the unit connections.

SD092761 ISSUE 30

e) All Pool Purifying Devices and Chemical Injection Systems must be fitted down stream of the ‘SERIES 2VARIHEAT’ unit with a non return valve to prevent concentrated chemicals back feeding into the heatexchangers. The practice of dosing chemicals direct into the Skimmer basket, which results inconcentrated corrosive liquid passing over vulnerable metal components must not be allowed.f) Water quality must be maintained not only relating to solids, etc. but for pH between 7.4 ± 0.4, and if poolwater is saline at a maximum concentration of 6% wt/wt. See secion 6, Warranty Exclusions for total list ofwater quality limits.

2.3.5) DETERMINING WATER FLOWa) Flow meter method

Ensure isolation valves ‘A’ and ‘B’ and bypass valves ‘C’ are fully open. Slowly close down bypass valve ‘C’until correct flow rate (see data sheet section 4) is shown on the flow meter .Remove handle and lock off valve ‘C’.

b) Differential Pressure Method (See fig 3).

By simply installing two filter pressure indicating gauges, one each on the inlet and outlet of the heat pump,and a locking type gate bypass valve in the bypass line, the flow rate though the heat pump can beaccurately determined by the difference in the readings of the gauges. This pressure drop is proportional tothe flow.Flow rate should be set at the maximum differential with a clean filter if fitted, this differential pressure willdrop as the filter becomes dirty. Provided the filter is cleaned before the minimum differential is reached(which would normally be the case with a well managed system) then no problems should be encounter.

Setting up the differential.

When the installation is complete, the procedure for setting the flow rate thought the heat pump using twogauges is as follows.

1. With the heat pump switched off, ensure isolation valves ‘A’, ‘B’ and bypass valve ‘C’ are fully open.

2. Switch on water circulating pump.

3. Note the water System Pressure on both gauges – they should read the same, but because ofmanufacturing tolerance they may read different.

For example; with a water system pressure of 5mhd the gauge on the inlet may read 5 and the outletgauge 5.5 therefore there is a STATIC ERROR DIFFERENCE of 0.5mhd

4. Gradually close the bypass valve ‘C’ until there is a difference in pressure between the two gaugesthat is equal to the required pressure drop (see section 4.0) observing any static error on the gaugesbefore beginning this process.

5. Lock the bypass valve, or render it tamper proof, when correct setting is achieved

See data sheet (section 4.0) for correct pool water pressure drop.

2.4 ELECTROLYTIC CORROSION IN SWIMMING POOLS

Electrolytic corrosion will occur when dissimilar metals that are in contact with each othercreate a potential difference between themselves. Sometimes separated by a conductivesubstance known as an electrolyte, the dissimilar metals will create a small voltage (potentialdifference) that allows the ions of one material to pass to the other.Just like a battery, ions will pass from the most positive material to the more negative material.

Anything more than 0.3 volts can cause the most positive material to degrade.

A swimming pool with its associated equipment can create this effect. The pool water being anideal electrolyte and components of the filtration circuit, heating system, steps, lights etc provid-ing the dissimilar metals needed to complete the circuit.Whilst these small voltages are rarely a safety threat, they can create premature failure throughcorrosion. Not dissimilar to corrosion through oxidation, electrolytic corrosion can cause com-plete failure of a metallic material in a very short period of time.

In order to prevent this type of corrosion all metallic components in contact with swimming poolwater should be bonded together using 10mm² bonding cable. This includes non-electricalitems such as metal filters, pump strainer boxes, heat exchangers, steps and handrails. It ishighly recommended that bonding be retrofitted to existing pools, which may not be protected bythis system.

SD092761 ISSUE 30

2.5 ELECTRICAL INSTALLATION

2.5.1 Electrical Safety – It is important to ensure that all aspects of the installation comply with thelatest I.E.E Regulations. It is also important to ensure that any remote devices which terminatewithin the pool hall are of the type and voltage as specified in the latest I.E.E Regulations

The machine should be installed in line with EMC2004/108/EC.

2.5.2 Protected Supply – Whilst not mandatory, Calorex recommend that an R.C.C.B is always fittedor that the supply is to local electricity authority recommendations, and that all ducting inbonded in in accordance with these regulations.

The supply to the machine should incorporate fuses or motor rated circuit breakers (Type GU,FAZC) to specified rating, (see Data Sheet). H.R.C fuses are recommended. An isolator must befitted within clear view and not more than 2 meters away. The isolator must have a minimum3mm air gap in the off position.

2.5.3 Inconsistent Electrical Supply – The following limits of operation must not be exceeded ifCalorex machines are to be guaranteed either in performance or warranty terms:-

Voltage Minimum MaximumSingle phase machines 207V 253VThree phase machines 360V 440VFrequency 47.5Hz 52.5Hz

N.B The voltage must be measured at the heat pump mains terminals with all the fans/compressors runningat the rated load condition.

2.5.4 Correct Cable Sizing – The cable supplying electricity to amachine with a given load must increase in cross sectional area(C.S.A) as the length increases in order that the voltage dropwithin the cable does not exceed recommended limits. Cablesizing should be calculated by an approved electrician withdue consideration to I.E.E and local codes of practice.

NOTE: The AW1270BVHF is fitted with a phase protection relay and will not runif the phases are not connected in correct order (phase sequence) or if thesupply voltage is 15% less than the nominal voltage. (415V for 3~N 50Hz) . Thelamp on the phase rotation relay, situated in the electric box, is illuminated whenthe phases are correctly connected and the voltage is sufficient.

SECTION 2.5 ELECTRICAL (cont).NOTE 1.These contacts are to enable the air temperature set back temperature to be remotely overrid-den.There is a 12 Volt output from these terminals and closing a remote switch will enable the unit toregain the normal operating air temperature for when the pool is in use.This can be done via a voltage free pool cover switch or some other form of voltage free switch.If this facility is used then the time clock on the control panel of the unit should be set to the"unoccupied" (II or 0) position.If this facility is not to be used then these terminals can be ignored.

NOTE 2.These are voltage free contacts rated at 2 Amp at 230 Volt.If the pool water pump is to be run via a time clock then these connections should go across theswitching contacts of the clock to ensure that if dehumidification demand occurs then the poolwater pump will start.The pool water pump will exceed the rated curent of these contacts therefore a contactor/relayshould be used to take the load of the pump. The switching action of the time clock shouldenergise the contactor/relay coil.If the pool water pump is to be run continuously then these contacts can be ignored.

NOTE 3.These are voltage free contacts rated at 2 Amp at 230 Volt.If the low pressure hot water supply to unit is to be governed by the unit then these contactsshould be utilised to bring water to the unit via the boiler, motorised valve, boiler pump etc.This is dependant on how the low pressure hot water supply to the unit has been designed.If the supply of low pressure hot water to the unit is not dependent on a signal from the unit thenthese contacts can be ignored.

a) Timeclock. Will require initial setting to time of day followed by setting up for switching periods occupied/unoccupied (see section 3.5.1).

b) Power Switch Should be switched to 'I' to turn on the SERIES 2 VARIHEAT unit. Note that on the off 'O' position the SERIES 2 VARIHEAT is still powered up and the machine should be isolated at the mains supply before removing any service panels .

c) Fresh Air Switch AUTO ' position will allow the dampers to be controlled as required by the control circuit of the SERIES 2 VARIHEAT unit. OFF ' position will override the SERIES 2 VARIHEAT control and keep the dampers at minimum fresh air. Typically this feature would be used on start up, until

the pool water and air reach the desired settings.

d) Humidity Control Should be set to show the desired maximum relative humidity in the pool hall (typically 60%).

e) Air Temp Control Should be set to show the desired air temperature required in the pool hall (typically 28°C but always 2°C above pool water temperature).

Setting theTecnologic Stats.Press down P and release, SP1 and Set Point will be displayed alternately. Press the Up or Down key to change the desired value of SP1. Once the desired value is displayed press P and release to memorise the value. The display will revert to the present reading.Note: If anything else shows on the display, leave alone for 1 minute, until the display returns to normal.

f) Water Temp Control Should be set to show the desired water temperature required in the pool (typically 26°C).

Setting theTecnologic Stats.Press down P and release, SP1 and Set Point will be displayed alternately. Press the Up or Down key to change the desired value of SP1. Once the desired value is displayed press P and release to memorise the value. The display will revert to the present reading.Note: If anything else shows on the display, leave alone for 1 minute, until the display returns to normal.

Setting alternative Stork Stats: Set by holding down the SET' or 'P' button and raising or lowering the digital display by pushing the 'up' 'down' symbol buttons to show the required setting .Do not change the diff.Factory Settings: Air 2ºC, Water 0.1ºC.

g) Set Back Air Temp Located behind the right hand electrical control panel Thermostat and pre-set by the commissioning engineer to the required set back or unoccupied air temperature (typically 24°C).

Indicates that there is a demand for the SERIES 2VARIHEAT unit to dehumidify.

Indicates that there is a demand for the SERIES 2VARIHEAT unit to heat the pool hall air .

Indicates that there is a demand for the SERIES 2 VARIHEAT to heat the pool water.

Indicates that there is a power supply on to theSERIES 2 VARIHEAT unit.

Check that the pool hall air flow and the pool water flow through the SERIES 2 VARIHEAT unit are within specified limits. Check contactor overloads, Control fuse and soft start overload (if fitted) and push all to reset .If fault light stays on call for service check.

This indicates that the SERIES 2 VARIHEAT unit istemporarily defrosting one or both of the evaporatorsto ensure efficient operation.

Indicates that the Fresh Air Switch (if fitted ) is set to ' Auto ' see above.

a) Is the building finished in accordance with the original plans and specification ?

b) Is the plenum chamber and all the ductwork insulated? Special attention should be made to theinsulation of the exhaust air ducting and fresh air inlet ducting to prevent condensation problems.

c) Are there any significant draughts in the pool hall or plant room (plenum installation) throughpoorly fitting doors , windows, pipe ducts, etc? This will let in unwanted ambient air raising theheating duty required.

d) Is Fresh Air suction and Exhaust Air discharge ducting, (if fitted) perfectly sealed fromplant room?NOTE: (c) and (d) above should be checked by measuring plant room and pool hallair temperatures.If the plant room is acting as a plenum chamber both temperaturesshould correspond. If the plantroom air temperature is lower, then ambient air is leaking in. This leak should be located and rectified.

e) Are the Fresh Air inlet and Exhaust air outlets (if fitted ) free from obstructions, i.e. undersizedgrilles, objects in path of exhaust air deflecting it back to the fresh air inlet, etc.

f) Is Set Back thermostat set correctly?

g) Is Time Clock set correctly?

h) Is Start Up, Fresh Air Off, feature required and if so is customer aware of when toswitch machine back to Auto (see section 3.2 (c)).

j) Removal of Fan Damper Plate will void warranty unless Fan Amps are verified to be belowF.L.A. (see data sheet section 4) with all panels and grilles fitted and the Evaporator dry.

NSS=UNOCCUPIED PERIOD AIR TEMP STAT (LPHW HEAT AIR).

OR 12v TERMINALS 10&11 CLOSED.

OCCUPIED MODE:-

=TIME CLOCK PIPS OUT,

OR TIME CLOCK MANUAL "I",

UNOCCUPIED MODE:-

=TIME CLOCK PIPS IN,

OR TIME CLOCK MANUAL "II" (0)

OR 12v TERMINALS 10&11 OPEN.

RH1=DEHUM STAT (COMP ON) (DAMPERS OPEN IF FITTED).

AS1=AIR STAT STAGE 1 (LPHW HEAT AIR).

AS2=AIR STAT STAGE 2 (DAMPERS OPEN).

WS1=WATER STAT STAGE 1 (MAX TEMP).

WS2=WATER STAT STAGE 2 (LPHW HEAT WATER).

KEY

1) SIGNAL TO START BOILER PUMP IS VIA TERMINAL BLOCKS 6 & 7 (VOLTAGE FREE SWITCH). SIGNAL TO START POOL FILTER VIA TERMINAL BLOCKS 8 & 9 (VOLTAGE FREE SWITCH).MACHINE WILL BRING ON POOL FILTER PUMP (IF IT IS NOT ALREADY RUNNING) WHENEVER THE COMPRESSOR RUNS. THE POOL FILTER PUMP WILL STOP WHEN RH1 IS SATISFIED UNLESS WS2 WATER HEATING REQUIRED (LPHW). WS2 WATER HEATING DEMAND ALONE WILL HOLD ON THE POOL FILTER PUMP PROVIDING THE POOL FILTER PUMP IS ALREADY RUNNING DUE TO THE CUSTOMERS TIME CLOCK SAMPLING PERIODS (SEE OWNERS MANUAL) OR COMPRESSOR RUN DEMAND (RH1). IF AFTER WS2 SIGNAL TO HOLD ON POOL PUMP THE MACHINE WATER PRESSURE SWITCH GOES OPEN CIRCUIT, NOTHING WILL CHANGE, ie PUMP SIGNAL TO RUN REMAINS UNTIL WS2 SATISFIED. PUMP MAY CONTINUE UNDER SEPARATE CUSTOMER CONTROL.

2) "SET POINT" OF THERMOSTATS IS REFERRED TO AS THE SWITCHING POINT FOR SIMPLICITY WHEN IN FACT THE RELAY OPERATES AT SETPOINT ± ½ OF THE HYSTERESIS (DIFF). (STORKS ONLY)

3) WHEN MACHINE ON DEFROST, COMPRESSOR STOPS BUT ALL OTHER FUNCTIONS OPERATE AS NORMAL.

4) IF SWITCH "A" SET TO "OFF" THE DAMPERS ARE FORCED TO CLOSE AND WILL NOT BE UNDER MACHINE "AUTO" CONTROL. IF FRESH AIR SWITCH IS SELECTED "OFF" OR UNOCCUPIED PERIOD REACHED DAMPERS WILL NOT CLOSE UNTIL THE DEMAND THAT ORIGINALLY OPENED THEM IS SATISFIED.

5) AIR STAT NEON (AS1) WILL SHOW DEMAND ON UNOCCUPIED SETTING BUT NOTHING WILL HAPPEN BECAUSE CONTROL IS BY SET BACK STAT (NSS).

6) TIME CLOCK MUST BE OVERRIDDEN AND UNOCCUPIED (PIPS IN) SELECTED IN ORDER THAT THE REMOTE 12v SWITCHING FEATURE CAN OPERATE. MACHINE TERMINALS 10 & 11 ARE 12vac, OPEN CIRCUIT = UNOCCUPIED, CLOSED CIRCUIT = OCCUPIED.
