11 4 Pipe connections General pipe connections Pipe installation must be carried out in accordance with current norms and directives. The system requires the radiator circuit to be designed for a low temperature heating medium. At lowest dimensioned outdoor temperature, the highest recommended temperatures are 55 C on the supply line and 45 C on the return line, but VVM 500 can handle up to 65 C. Equip the product with a safety valve on both the boiler side and domestic coil. Overflow water from the safety valve goes via overflow cups to a drain so that hot water splashes cannot cause injury. The entire length of the overflow water pipe must be inclined to prevent water pockets and must also be frost proof. NIBE recommends installing VVM 500 as close to the heat pump as possible for optimum comfort. For further information about the location of different components, see section "Installation alternatives" in this manual. Any high points in the climate system, must be equipped with air vents. The pipe systems need to be flushed out before the indoor module is connected so that any debris cannot damage component parts. Switch (SF1) must not be moved to "" or " " until VVM 500 has been filled with water. Otherwise the temperature limiter, thermostat and the immersion heater etc can be damaged. Boiler and radiator volumes Internal volume in VVM 500 for calculating expansion vessel is 500 l. The expansion vessel's volume must be at least 5 % of the system's total volume. Example table Total volume (l) (indoor module and climate system) Volume (l) expansion vessel H Total volume (l) (indoor module and climate system) 700 1,000 Volume (l) expansion vessel Expansion vessel not supplied with the product. Equip the product with an expansion vessel. The pre-pressure of the pressure expansion vessel must be 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 a maximum permitted height difference of 5 m. If the standard initial pressure in the pressure vessel is not high enough it can be increased by filling via the valve in the expansion vessel. The expansion vessel's standard initial pressure must be entered in the check list on page 5. Any change in the initial pressure affects the ability of the expansion vessel to handle the expansion of the water. System diagram VVM 500 consists of a hot water coil, immersion heater, circulation pumps, buffer vessel, control system and is prepared for use with solar panels. VVM 500 connects to the climate system. VVM 500 is designed for connection and communication with F2020/F2025/F2026/F2030/F2040/F2120/F2300, which together make up a complete heating installation. When it is cold outdoors F2020/F2025/F2026/F2030/F2040/F2120/F2300 works with VVM 500 and if the outdoor air temperature falls below the heat pump stop temperature, all heating is carried out by VVM EB101 -EB101 -FL10 -XL1 -XL2 -QM1 -QM40 -HQ1-QM41 -EB15 -EB15-FL2 -EB15 -CM1 -FL1 -RM1 -QM Chapter 4 Pipe connections 11

Chapter 5 Electrical connections 25

26 VVM 500 APH Room sensor VVM 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 set temperature is required. A suitable location is on a free inner wall in a hall approx. 1.5 m above the floor. It is important that the sensor is not obstructed from measuring the correct room temperature by being located, for example, in a recess, between shelves, behind a curtain, above or close to a heat source, in a draft from an external door or in direct sunlight. Closed radiator thermostats can also cause problems. The indoor module operates without the sensor, but if one wishes to read off the accommodation's indoor temperature in VVM 500's display, the sensor must be installed. Connect the room sensor to X6:3 and X6:4 on the input board (AA3). If the sensor is to be used to change the room temperature in C and/or to stabilise the room temperature, the sensor must be activated in menu If the room sensor is used in a room with underfloor heating, it should only have an indicatory function, not control of the room temperature. Caution AA3-X6 External RG 05 BT50 VVM F AA3-X6 Changes of temperature in accommodation take time. For example, short time periods in combination with underfloor heating will not give a noticeable difference in room temperature. Communication If VVM 500 is to be connected to the heat pump, it is connected to terminal blocks X4:13, X4:14 and X4:15 on the input board (AA3).

The task of the heating curve is to give an even indoor temperature, regardless of the outdoor temperature, and thereby energy efficient operation. It is from this heating curve that the indoor module s control computer determines the temperature of the water to the heating system, supply temperature, and therefore the indoor temperature. Select the heating curve and read off how the supply temperature changes at different outdoor temperatures here. If there is access to cooling the same settings can be made for the cooling curve. Curve coefficient The slopes of the heating /cooling curves indicate how many degrees the supply temperature is to be increased/reduced when the outdoor temperature drops/increases. A steeper slope means a higher supply temperature for heating or a lower supply temperature for cooling at a certain outdoor temperature. 34 Chapter 6 Commissioning and adjusting

35 Supply temperature C 70 Brantare Steeper kurvlutning curve slope C Outdoor UTETEMPERATUR temperature The optimum slope depends on the climate conditions in your location, if the house has radiators or under floor heating and how well insulated the house is. The curve is set when the heating installation is installed, but may need adjusting later. Normally, the curve will not need further adjustment. Caution When making fine adjustments of the indoor temperature, the curve must be offset up or down instead, this is done in menu 1.1 temperature. Curve offset An offset of the curve means that the supply temperature changes as much for all the outdoor temperatures, e.g. that a curve offset of +2 steps increases the supply temperature by 5 C at all outdoor temperatures. Flow line temperature maximum and minimum values Because the flow line temperature cannot be calculated higher than the set maximum value or lower than the set minimum value the heating curve flattens out at these temperatures. Caution Under floor heating system are normally max flow line temperature set to between 35 and 45 C. Must be restricted with underfloor cooling min. flow line temp. to prevent condensation. Check the max temperature for your floor with your installer/floor supplier. The figure at the end of the curve indicates the curve slope. The figure beside the thermometer gives the curve 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 To select another curve (slope): If you only have one climate system, the number of the curve is already marked when the menu window opens. 1. Select the climate system (if more than one) for which the curve is to be changed. 2. When the climate system selection has been confirmed, the curve number is marked. 3. Press the OK button to access the setting mode 4. Select a new curve. The curves are numbered from 0 to 15, the greater the number, the steeper the slope and the greater the supply temperature. Curve 0 means that own curve (menu 1.9.7) is used. 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 temperature at the selected outdoor temperature. 4. You can now select to take read outs for different outdoor temperatures by turning the control knob to the right or left and read off the corresponding flow 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 to stabilise. If it is cold outdoors and the room temperature is too low, increase the curve slope by one increment. If it is cold outdoors and the room temperature is too high, lower the curve slope by one increment. If it is warm outdoors and the room temperature is too low, increase the curve offset by one increment.

51 9 Service Service actions Servicing should only be carried out by persons with the necessary expertise. When replacing components on VVM 500 only replacement parts from NIBE may be used. Emergency mode Emergency mode is used in event of operational interference and in conjunction with service. Hot water capacity 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 controlled by the thermostat (FD1-BT30). It can be set to 35 or 45 C. Only the circulation pumps and electric additional heat are active. The electrical additional heat power in emergency mode is set in the immersion heater board (AA1). See page 27 for instructions. Emptying the hot water coil The hot water coil is most easily drained by detaching the cold water pipe at the coils's entry to the reservoir. Draining the climate system In order to carry out service on the climate system, it may be easier to drain the system first using drain valve (QM1). There may be some hot water when draining the heating medium side/climate system. There is a risk of scalding.

Info menu indoor module All the indoor module measured values are gathered under menu 3.1 in the indoor module menu system. Looking through the values in this menu can often simplify finding the source of the fault. Manage alarm alarm info / action reset alarm aid mode Low pressure alarm In the event of an alarm, some kind of malfunction has occurred, which is indicated by the status lamp changing from green continuously to red continuously. In addition, an alarm bell appears in the information window. Alarm In the event of an alarm with a red status lamp a malfunction has occurred that the indoor module cannot remedy itself. In the display, by turning the control knob and pressing the OK button, you can see the type of alarm it is and reset it. You can also choose to set the indoor module to aid mode. info / action Here you can read what the alarm means and receive tips on what you can do to correct the problem that caused the alarm. reset alarm In most cases it is enough to select "reset alarm" 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 visible and a menu called alarm is visible in the display, the problem that caused the alarm remains. If the alarm disappears and then returns, see the troubleshooting section (page 54). aid mode "aid mode" is a type of emergency mode. This means that the indoor module produces heat and/or hot water, even though there is some kind of problem. This could mean that the heat pump's compressor is not running. In this case the immersion heater produces heat and/or hot water. To select aid mode an alarm action must be selected in the menu Chapter 10 Disturbances in comfort Caution Selecting "aid mode is not the same as correcting the problem that caused the alarm. The status lamp will therefore continue to be red. Troubleshooting If the operational interference is not shown in the display the following tips can be used: Basic actions Start 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).
