If you press the Info button in the initial menu you will receive continuous
information about the heat pump's operation and working temperatures.
Here follows a few of the windows displayed:
The heat pump is in standby mode.
The heat pump is producing hot water. You see at which temperature
the heat pump will stop and the present temperature. Note that the stop
temperature is read at the bottom of the hot water heater. The hot water is a
few degrees warmer.
The heat pump and additional heat are running.
The heat pump has received signals that it should produce heating. It now
waits for the restart time to countdown to zero.
Return to the initial menu by pressing one of the buttons or turn the dial.
Set the heating
It is easy to set the heating level on the heat pump. However, before we
explain how to do this it is important to understand the relation between the
outdoor temperature, return temperature and heat curve slope. The easiest
way to explain the relation is with a heat curve.
Heat cur ve
You use the heat curve to help set the indoor temperature you would like.
The heat pump is controlled by the outdoor temperature. When the weather
becomes colder the heat pump ensures more heating is produced automati-
cally.
Return temperature:
The return temperature is the temperature of the water that returns to the
heat pump from the radiators. The water led out from the heat pump to the
heating system is normally 7-10ºC higher than the return temperature.
When the outdoor temperature is -10ºC and curve 4 is set, the pump
attempts to keep the return water at approximately 40ºC. If instead the
temperature is 35ºC, the fl ow water is heated until the return water is warm
enough.
