NIBE™ VVM 500Chapter 3 | Indoor module's design10

General pipe connectionsPipe installation must be carried out in accordance withcurrent norms and directives.

The system requires the radiator circuit to be designedfor a low temperature heating medium. At lowest di-mensioned outdoor temperature, the highest recom-mended temperatures are 55 °C on the supply line and45 °C on the return line, but VVM 500 can handle upto 65 °C.

NOTE

Equip the product with a safety valve on boththe boiler side and domestic coil.

Overflow water from the safety valve goes via overflowcups to a drain so that hot water splashes cannot causeinjury. The entire length of the overflow water pipemust be inclined to prevent water pockets and mustalso be frost proof.

NIBE recommends installing VVM 500 as close to theheat pump as possible for optimum comfort. For furtherinformation about the location of different compon-ents, see section "Installation alternatives" in thismanual.

NOTE

Any high points in the climate system, mustbe equipped with air vents.

NOTE

The pipe systems need to be flushed out be-fore the indoor module is connected so thatany debris cannot damage component parts.

NOTE

Switch (SF1) must not be moved to "" or " "until VVM 500 has been filled with water.Otherwise the temperature limiter, thermostatand the immersion heater etc can be dam-aged.

Boiler and radiator volumes

H

Internal volume in VVM 500for calculating expansionvessel is 500 l. The expansionvessel's volume must be atleast 5 % of the system's totalvolume.

Example table

Volume (l)expansionvessel

Totalvolume (l)(indoormodule andclimate sys-tem)

25500

Volume (l) expansionvessel

Total volume (l) (indoormodule and climate sys-tem)

35700

501,000

NOTE

Expansion vessel not supplied with theproduct. Equip the product with an expansionvessel.

The pre-pressure of the pressure expansion vessel mustbe dimensioned according to the maximum height (H)between the vessel and the highest positioned radiator,see figure. A pre-pressure of 0.5 bar (5 mvp) means amaximum permitted height difference of 5 m.

If the standard initial pressure in the pressure vessel isnot high enough it can be increased by filling via thevalve in the expansion vessel. The expansion vessel'sstandard initial pressure must be entered in the checklist on page 5.

Any change in the initial pressure affects the ability ofthe expansion vessel to handle the expansion of thewater.

System diagramVVM 500 consists of a hot water coil, immersion heater,circulation pumps, buffer vessel, control system and isprepared for use with solar panels. VVM 500 connectsto the climate system.

VVM 500 is designed for connection and communica-tion withF2020/F2025/F2026/F2030/F2040/F2120/F2300,which together make up a complete heating installa-tion.

When it is cold outdoorsF2020/F2025/F2026/F2030/F2040/F2120/F2300works with VVM 500 and if the outdoor air temperaturefalls below the heat pump stop temperature, all heatingis carried out by VVM 500.

Room sensorVVM 500 is supplied with a room sensor enclosed(BT50). The room sensor has up to three functions:1. Show current room temperature in VVM 500's

display.2. Option of changing the room temperature in °C.3. Makes it possible to change/stabilise the room

temperature.

Install the sensor in a neutral position where the settemperature is required. A suitable location is on a freeinner wall in a hall approx. 1.5 m above the floor. It isimportant that the sensor is not obstructed frommeasuring the correct room temperature by beinglocated, for example, in a recess, between shelves, be-hind a curtain, above or close to a heat source, in adraft from an external door or in direct sunlight. Closedradiator thermostats can also cause problems.

The indoor module operates without the sensor, butif one wishes to read off the accommodation's indoortemperature in VVM 500's display, the sensor must beinstalled. Connect the room sensor to X6:3 and X6:4on the input board (AA3).

If the sensor is to be used to change the room temper-ature in °C and/or to stabilise the room temperature,the sensor must be activated in menu 1.9.4.

If the room sensor is used in a room with underfloorheating, it should only have an indicatory function, notcontrol of the room temperature.

Output lockingVVM 500 follows applicable building regulations (BBR).This means that the maximum power output (maxim-um installed electrical output for heating) can be lockedin menu 5.1.13. To then change the maximum poweroutput, parts of the product must be replaced.


Optional connections

Load monitorWhen many power consumers are connected in theproperty at the same time as the electric additionalheat is operating, there is a risk of the property's mainfuse tripping. The indoor module has integrated loadmonitors that control the electrical steps for the elec-trical addition by redistributing the power betweenthe different phases or disengaging in event of over-load in a phase. Reconnection occurs when other cur-rent consumption is reduced.

Connecting current sensors

A current sensor should be installed on each incomingphase conductor in to the distribution box to measurethe current. The distribution box is an appropriate in-stallation point.

Connect the current sensors to a multi-core cable in anenclosure next to the distribution box. Use a multi-corecable of at least 0.5 mm2 from the enclosure to theindoor module.

Connect the cable to the input board (AA3) on terminalX4:1-4 block - where X4:1 is the common terminal blockfor the three current sensors.

The size of the property's main fuse is set in menu5.1.12.

The prescribed heating curve for your house can beviewed in the menu curve . The task of the heatingcurve is to give an even indoor temperature, regardlessof the outdoor temperature, and thereby energy effi-cient operation. It is from this heating curve that theindoor module’s control computer determines thetemperature of the water to the heating system, supplytemperature, and therefore the indoor temperature.Select the heating curve and read off how the supplytemperature changes at different outdoor temperat-ures here. If there is access to cooling the same settingscan be made for the cooling curve.

Curve coefficientThe slopes of the heating /cooling curves indicate howmany degrees the supply temperature is to be in-creased/reduced when the outdoor temperaturedrops/increases. A steeper slope means a higher supplytemperature for heating or a lower supply temperaturefor cooling at a certain outdoor temperature.

Steeper curve slope

The optimum slope depends on the climate conditionsin your location, if the house has radiators or underfloor heating and how well insulated the house is.

The curve is set when the heating installation is in-stalled, but may need adjusting later. Normally, thecurve will not need further adjustment.

Caution

When making fine adjustments of the indoortemperature, the curve must be offset up ordown instead, this is done in menu 1.1 tem-perature .

Curve offsetAn offset of the curve means that the supply temperat-ure changes as much for all the outdoor temperatures,e.g. that a curve offset of +2 steps increases the supplytemperature by 5 C at all outdoor temperatures.

Flow line temperature– maximum andminimum valuesBecause the flow line temperature cannot be calculatedhigher than the set maximum value or lower than theset minimum value the heating curve flattens out atthese temperatures.

Caution

Under floor heating system are normally maxflow line temperature set to between 35 and45 °C.

Must be restricted with underfloor coolingmin. flow line temp. to prevent condensation.

Check the max temperature for your floor withyour installer/floor supplier.

The figure at the end of the curve indicates the curveslope. The figure beside the thermometer gives thecurve offset. Use the control knob to set a new value.Confirm the new setting by pressing the OK button.

Curve 0 is an own curve created in menu 1.9.7.

To select another curve (slope):

NOTE

If you only have one climate system, the num-ber of the curve is already marked when themenu window opens.

1. Select the climate system (if more than one) forwhich the curve is to be changed.

2. When the climate system selection has been con-firmed, the curve number is marked.

3. Press the OK button to access the setting mode4. Select a new curve. The curves are numbered from

0 to 15, the greater the number, the steeper theslope and the greater the supply temperature.Curve 0 means that own curve (menu 1.9.7) isused.

5. Press the OK button to exit the setting.

To read off a curve:1. Turn the control knob so that the ring on the shaft

with the outdoor temperature is marked.2. Press the OK button.3. Follow the grey line up to the curve and out to the

left to read off the value for the supply temperatureat the selected outdoor temperature.

4. You can now select to take read outs for differentoutdoor temperatures by turning the control knobto the right or left and read off the correspondingflow temperature.

5. Press the OK or Back button to exit read off mode.

TIP

Wait 24 hours before making a new setting,so that the room temperature has time tostabilise.

If it is cold outdoors and the room temperatureis too low, increase the curve slope by one in-crement.

If it is cold outdoors and the room temperatureis too high, lower the curve slope by one incre-ment.

If it is warm outdoors and the room temperat-ure is too low, increase the curve offset by oneincrement.

If it is warm outdoors and the room temperat-ure is too high, lower the curve offset by oneincrement.

Service actionsNOTE

Servicing should only be carried out by personswith the necessary expertise.

When replacing components on VVM 500 onlyreplacement parts from NIBE may be used.

Emergency modeEmergency mode is used in event of operational inter-ference and in conjunction with service. Hot water ca-pacity is reduced in this mode.

Emergency mode is activated by setting switch (SF1)in mode " ". This means that:■ The status lamp illuminates yellow.■ The display is not lit and the control computer is not

connected.■ The temperature at the immersion heater is con-

trolled by the thermostat (FD1-BT30). It can be setto 35 or 45 °C.

■ Only the circulation pumps and electric additionalheat are active. The electrical additional heat powerin emergency mode is set in the immersion heaterboard (AA1). See page 27 for instructions.

Emptying the hot water coilThe hot water coil is most easily drained by detachingthe cold water pipe at the coils's entry to the reservoir.

Draining the climate systemIn order to carry out service on the climate system, itmay be easier to drain the system first using drain valve(QM1).

NOTE

There may be some hot water when drainingthe heating medium side/climate system.There is a risk of scalding.

In most cases, the indoor module notes operationalinterference (operational interference can lead to dis-turbance in comfort) and indicates this with alarms andshows action instructions in the display.

Info menu indoor moduleAll the indoor module measured values are gatheredunder menu 3.1 in the indoor module menu system.Looking through the values in this menu can oftensimplify finding the source of the fault.

alarm

In the event of an alarm, some kind of malfunction hasoccurred, which is indicated by the status lamp chan-ging from green continuously to red continuously. Inaddition, an alarm bell appears in the informationwindow.

AlarmIn the event of an alarm with a red status lamp a mal-function has occurred that the indoor module cannotremedy itself. In the display, by turning the control knoband pressing the OK button, you can see the type ofalarm it is and reset it. You can also choose to set theindoor module to aid mode.

info / actionHere you can read what the alarm meansand receive tips on what you can do to correct theproblem that caused the alarm.

reset alarm In most cases it is enough to select "resetalarm" to correct the problem that caused the alarm.If a green light illuminates after selecting "reset alarm"the alarm has been remedied. If a red light is still visibleand a menu called ”alarm” is visible in the display, theproblem that caused the alarm remains. If the alarmdisappears and then returns, see the troubleshootingsection (page 54).

aid mode "aid mode" is a type of emergency mode.This means that the indoor module produces heatand/or hot water, even though there is some kind ofproblem. This could mean that the heat pump's com-pressor is not running. In this case the immersionheater produces heat and/or hot water.

NOTE

To select aid mode an alarm action must beselected in the menu 5.1.4.

Caution

Selecting "aid mode” is not the same as correct-ing the problem that caused the alarm. Thestatus lamp will therefore continue to be red.

TroubleshootingIf the operational interference is not shown in the dis-play the following tips can be used:

Basic actionsStart by checking the following possible fault sources:■ The switch's (SF1) position.■ Group and main fuses of the accommodation.■ The property's earth circuit breaker.■ The indoor module's miniature circuit breaker (FA1).■ The indoor module's temperature limiter (FD1).■ Correctly set load monitor (if installed).

Low hot water temperature or a lack of hotwater■ (QM10) for the water heater.

(QM10) for the hot water.■ Indoor module in incorrect operating mode.■ If mode "manual" is selected, select "addition".

■ Large hot water consumption.■ Wait until the hot water has heated up. Temporar-

ily increased hot water capacity (temporary lux)can be activated in menu 2.1.

■ Too high domestic water flow.■ Reduce the domestic water flow, see diagram of

hot water capacity on page 59.■ Too low hot water setting.■ Enter menu 2.2 and select a higher comfort mode.

Low room temperature■ Closed thermostats in several rooms.■ Indoor module in incorrect operating mode.■ Enter menu 4.2. If mode "auto" is selected, select

a higher value on "stop heating" in menu 4.9.2.■ If mode "manual" is selected, select "heating". If

this is not enough, select "addition".■ Too low set value on the automatic heating control.■ Enter menu 1.1 "temperature" and adjust the offset

heating curve up. If the room temperature is onlylow in cold weather the curve slope in menu 1.9.1"heating curve" needs adjusting up.

■ "Holiday mode" activated in menu 4.7.■ Enter menu 4.7 and select "Off".

■ External switch for changing the room heating activ-ated.■ Check any external switches.

■ Air in the climate system.■ Vent the climate system (see page 32)
