FOR THE USER
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 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
automatically.
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.
Outdoor temperature:
The outdoor temperature determines how much heating the heat pump
should produce. A sensor placed outdoors sends signals to the control unit,
which then adjusts the heat pump.
Cur ve slope:
You can change the curve slope to increase or decrease the heating in the
house. The scale is between 0-10.
On delivery the heat pump curve
slope is set to position 4. This means
that the return temperature is +35ºC
when it is 0ºC outdoors.
