11.8. Requirements for indoor unit field wiring
Selection and sizing should be done in accordance with the
applicable legislation based on the information in the table below:
11.9. Routing
The indoor unit has several openings on the bottom side for field
wiring. Use the appropriate opening to route the high voltage, low
voltage and power supply wires as shown in the figure below.
11.10.Indoor switch box connections
Connection of control signals and thermistor cable
1 Indoor unit control signals
2 Indoor unit pump and heater control signals
3 Thermistor interconnection cable
In case the EKCBX/H008BCV3 control box is to
be connected to a EBHQ00*BAV3 unit, there is no
need to purchase the obligatory EKCOMCAB1
thermistor interconnection cable option. Refer to
figure 1 for procedure on how to recuperate the
thermistor interconnection cable that originally was
supplied with the EBHQ00*BAV3 unit.
4 In case no EKHW* option with booster heater is
installed, connect an extra ground wire to the
ground terminal.
5 Normal kWh rate power supply
1 Remove the control box cover.
2 Using the appropriate cables, route and connect the control
cables to the appropriate terminals as shown on the wiring
diagram supplied with the unit and according to the figure above.
3 Route and connect the thermistor interconnection cable to the
appropriate terminal as shown on the wiring diagram supplied
with the unit and according to the figure above.
4 Route the cables through the cable holders and secure the
cables to the cable tie mountings with cable ties as shown in the
figure above.
5 Close the control box cover. Take care not to pinch any wires.
Connection heater kit signals (if applicable)
Refer to the installation manual of the EKMBUH heater kit.

- Space heating and cooling application with a room thermostat suitable for heating cooling changeover connected to the unit heating is provided through floor heating loops and fan coil units cooling is provided through the fan coil units only 11
- Space heating only application without room thermostat connected to the unit the temperature in each room is controlled by a valve on each water circuit domestic hot water is provided through the domestic hot water tank which is connected to the unit 11
- The by pass valve should be selected as such that at all time the minimum water flow as mentioned in the chapter piping connection work in the ebhq outdoor unit installation manual is guaranteed 11
- The unit 1 will operate to achieve the target leaving water temperature as set on the user interface 11
- The unit can be configured so that at low outdoor temperatures the domestic water is exclusively heated by the booster heater this assures that the full capacity of the heat pump is available for space heating 11
- When circulation in each space heating loop fhl1 is controlled by remotely controlled valves m1 it is important to provide a by pass valve 8 to avoid the flow switch safety device from being activated 11
- When domestic water heating mode is enabled either manually by the user or automatically through a schedule timer the target domestic hot water temperature will be achieved by a combination of the heat exchanger coil and the electrical booster heater 11
- When the domestic hot water temperature is below the user configured set point the 3 way valve will be activated to heat the domestic water by means of the heat pump in case of large domestic hot water demand or a high domestic hot water temperature setting the booster heater 9 can provide auxiliary heating 11
- With no thermostat connected to the unit 1 the pump 3 can be configured to operate either as long as the unit is on or until the required water temperature is reached 11
- Application 4 12
- Application 5 12
- Always install a 3 way valve even if no domestic hot water tank is installed this to ensure that the freeze protection function see 4 04 freeze protection function on page 27 can operate when the boiler is active 13
- Be sure that the boiler and the integration of the boiler in the system is in accordance with the applicable legislation 13
- C onfiguration b when the room thermostat requests heating either the ebhq unit or the boiler starts operating depending on the outdoor temperature status of permission signal for the auxiliary boiler when the permission is given towards the boiler the space heating operation by the ebhq unit will be automatically switched off for more details see field setting c 02 c 04 13

- Heating of the domestic hot water by the heat pump will be started as soon as the domestic hot water temperature reaches the heat pump off temperature 31
- Heating of the domestic hot water by the heat pump will be stopped by switching the 3 way valve 31
- Information 31

- See illustration 31
- The dt temperature difference for heat pump domestic water heating mode field settings determine the temperatures at which heating of the domestic hot water by the heat pump will be started i e the heat pump on temperature and stopped i e the heat pump off temperature when the domestic hot water temperature drops below the heat pump on temperature 31
- The heat pump off temperature and the heat pump on temperature and its relation with field settings 6 00 and 6 01 are explained in the illustration below 31
- The maximum domestic hot water temperature that can be reached with the heat pump is 50 31
- The storage set point can be accessed directly using the 31
- When setting 4 03 0 2 or 4 special attention to setting 6 00 is recommended a good balance between the required domestic hot water temperature and heat pump on temperature 31
- 8 03 booster heater delay time specifies the start up time delay of the booster heater operation when heat pump domestic water heating mode is active 34
- 8 04 additional running time at 4 02 f 01 specifies the additional running time on the maximum running time at outdoor temperature 4 02 or f 01 see figure below 34
- By adapting the booster heater delay time versus the maximum running time an optional balance can be found between the energy efficiency and the heat up time 34
- Example 4 03 1 34
- However if the booster heater delay time is set too high it might take a long time before the domestic hot water reaches its set temperature upon domestic hot water mode request 34
- Information 34
- Notice 34
- Take care that 8 03 is always in relation with the maximum running time 8 01 34
- The delay timer starts from booster heater on temperature 34
- The full advantage of 8 04 will be applicable if setting 4 03 is not 1 34
- The purpose of 8 03 is to delay the booster heater in relation with the heat pump operation time in domestic water heating mode 34
- The setting 8 03 has only meaning if setting 4 03 1 setting 4 03 0 2 3 4 limits the booster heater automatically in relation to heat pump operation time in domestic water heating mode 34
- When heat pump is active in domestic water heating mode the delay time of booster heater is 8 03 34
