Problem
The telestates call for heat, but the heat
pump does not start
El-supplementation is turned on much or
always
AIR has a large power consumption
Possible cause
During the spring and autumn transition
periods, some space telestates may call
for heat, but the heat pump does not
start.
This may be because the temperature in
the extract air is warm enough compared
to the temperature set in the control
panel. That is, the exhaust air is an
average of the room's room temperatu-
res, as some rooms are hot and others
are cold.
Since the ventilation section considers
the average temperature of the house to
be high enough, it blocks the heat pump
from running. This does it to save energy
and to prevent the ventilation part and
the heat pump part from counteracting
each other.
The heat pump will not work effectively,
which may be due to various reasons.
One must expect that electricity con-
sumption in the first year will be greater
than expected. This is quite natural as
the house must dry out.
The higher humidity in the first year
means that it costs more energy to heat
the house.
This may also be because the heat pump
does not run optimally for various rea-
sons.
Solution
If you still want to heat in some rooms,
despite the average temperature of the
house being warm enough, you can acti-
vate this function below: Settings / Cen-
tral heating in the Menu item: Cooling and
heating at the same time
This means that the cooperation bet-
ween the ventilation part and the heat
pump part ends, and if there is a need for
heat in some rooms, the heat pump will
start even if the ventilation part detects
that the house is warm enough.
- Check that there is no ice in the evapo-
rator surface in the outdoor unit. It pre-
vents the air from getting through. Make
a manual defrost.
- Check that the evaporator surface in
the outdoor unit is not stopped with lea-
ves and other debris that can prevent the
air from getting through. Clean the
evaporator surface.
- Check that the hoses between the out-
door unit and the indoor unit are properly
insulated so that there is no excessive
heat loss.
- Check that there is a proper flow in the
circuit between the outer part and the
inner part.
