temperature if the room temperature in the critical room can not be
maintained with the calculated return water temperature setpoint
form ambient compensation.
Room compensation has two settings, first the wanted setpoint in
the room and second the maximum number of degrees the return
water temperature may be increased to maintain the wanted room
temperature. Typical values would be 20 °C for room temperature and
10 °C for maximum increase of return water temperature –

Room temperature compensation can only increase the return water
temperature with respect to the calculated return water temperature
from the ambient compensation function. It is therefore important that
the ambient compensation is adjusted to minimum values for return
water temperature
Heating control – On/Off room temperature control
Room temperature can be controlled based on a simple start and stop
of the heatpump.
Room temperature setpoint is set on the user menu –
Room temp.

and the acceptable difference is set in installer menu -
Heating settings.Heating neutral zone .
When the room temperature is below the setpoint minus half of the
difference, the heat source reference setpoint is set to the maximum
allowable temperature. When the room temperature is above the
se half of the allowable difference, the heat source is stopped
by setting the reference setpoint to minimum allowable temperature.
Minimum and maximum return water temperatures are respected and
so are the restart times for the compressor. Hot tap water production
can overrule this function.
If the room temperature sensor is defect, the reference for the returns
water temperature is set to

Heating control
If heating is activated, the controllers will primarily use the heat pump
controller for heating and only use supplemental (electrical or boiler)
heating if the capacity of the heat pump is too low.
