    Fill the system with water The system can now be filled with water to around 1 bar pressure. Ensure that all air is removed from the system by mechanical flushing. This heat pump has a pump run switch on the small PCB under the front cover of the heat pump.

    2. System configuration There are 2 common configurations, A or B for heating and either can also have DHW, C: A) Heat pump using own controller as room thermostat B) Heat pump using additional central heating controller as room thermostat C) Heating configuration A or B with DHW Set the parameters according to the 3 tables below.

    2.2. System B: Heat pump switched on/off by room thermostat(s) This could be a simple system with a single central heating controller or multiple zones, with or without a buffer tank. The key fact being that the room thermostats(s) switch the heat pump on and off according to the temperatures and times set on the room thermostat(s) The heat pumps controller is still needed to set heat pumps settings, as an overall heating on/off switch and for DHW control if you are heating a hot water cylinder.

    2.3. System C, A or B with a Hot Water Cylinder (DHW) Control of DHW by an Ikir2 is entirely independent of the space heating control configuration. The hot water cylinder is heated via a 3-way valve that gives hot water priority, when it is enabled. The 3-way valve is controlled from the heat pump, and needs to be enabled The temperature the heat pumps heats the potable hot water to is controlled via a sensor in the hot water cylinder connected to the heat pump;...

    3. System Operational Checks Once the heat pump is set up it is a very good idea to check that everything works as intended and that the heat pump starts and stops when it should in response to the controls used, and there is flow rate in manifolds when there should be and radiators get hot etc.

  • Page 8: System A Test Procedure

    3.1. System A test procedure By default the heat pumps controller is not set up to be a room thermostat but can still turn the heating on and off, however it will not turn off in response to room temperature if the correct settings haven’t been changed.

  • Page 9: System B Test Procedure

    3.2. System B test procedure If controls other than the heat pumps controller are being used the heat pump should start if 1 or more controls call for heat – flame symbol shows. When no controls call for heat the heat pump should stop. Test If not already on switch heat pump on using top left hand button –...

  • Page 10: A Or B With Dhw Test Procedure

    3.3. A or B with DHW test procedure The heat pump does not come set up to heat DHW. To do so requires that DHW heating is enabled; the DHW sensor wired into the heat pump; and the DHW sensor input enabled. If the either of the settings are not set, you will not be able to select DHW heating.
