8.1 Heat Pump Remote Control Unit

The heat pump can be switched on and off by means of the remote control positioned inside the building. Switching off in this case means switching to a "standby" function, i.e. as long as the heat pump is supplied with mains power, the frost protection function of the heat pump remains active. If the water temperature is too low, first the heating circulating pump, and if this is not enough, also the compressor must be put in operation. The remote control allows you to set the heating or cooling operating mode (the switchover delay from the heating to the cooling mode, or vice-versa, is 10 min.) as well as the temperature level of the heating water.

8.3 Heating Function

Set switch (1) to position On (I) to put heat pump into operation. The heating mode can be preselected by placing switch (3) to the Heating () position. The desired return temperature can be set using selector dial (4), the relevant call for heat is controlled by the potentiometer and lies within a range of min. 10 °C and max. 55 °C. If the preset temperature is reached, the heat pump switches off. Once the return temperature drops below the preset temperature by 4 Kelvin, the heat pump switches back on. In the event that the preset return temperature cannot be reached, the output for the back-up heater cuts in after approx. 1 hour. The heat pump cannot be restarted until a minimum time delay of 5 minutes has elapsed. At a supply temperature of approx. 60 °C or if the air temperature is too low, the heat pump switches off.
