For the property owner
9.5.2.2 Heat pump A1-A3
In the “Heat pump” menu you make settings for the heat
pumps which have been defined.
Compressor A1 Blocked (Blocked /Permitted)
The heat pump is supplied with a blocked compressor.
Permitted means that the compressor is allowed to operate.
Stop at outdoor temp °C -15 (-22...10)
This menu appears if the heat pump is a CTC EcoAir. At
this temperature the compressor is no longer permitted to
operate. The heat pump re-starts 2 ° C warmer than the set
value. The lowest outdoor re-start temperature is -18 ° C.
Delay between HP 30 (5 to 180)
This is used to set the delay time before the second heat
pump in the system is allowed to start, when the first heat
pump is already operating. This value is also valid for the
amount of time that will pass before the third heat pump is
allowed to start, when the first and second heat pumps are
operating, and so on.
NOTE: Only indicated for heat pump A1.
Prio. EcoAir/EcoPart °
C 7 (-20 to 15)
This temperature setting controls the prioritisation between
the EcoAir air/water heat pump and the EcoPart liquid/water
heat pump, if both of these are connected to the EcoZenith.
The factory value is 7°C; this means that the EcoAir is
prioritised for outside temperatures from 7°C and warmer.
NOTE: Only indicated for heat pump A1.
Cont. brine pump on No (No/Yes)
Setting for whether the brine pump is permitted to run all the
time or permitted to start and stop.
Applies to EcoPart heat pumps only.
Compressor stop at brine °C -5 (-7 to -5)
This menu defines the brine temperature at which the
compressor will be stopped.
Applies to EcoPart heat pumps only.
Brine pump on 10 days Off (Off/On)
After installation is complete, you can choose to run the
brine pump constantly for 10 days to remove air from the
system.
Applies to EcoPart heat pumps only.
Tariff HP Off (Off/On)
This is used when a dual tariff is used with lower energy
costs at set hours of the day. The heat pump can then take
advantage of reduced primary energy costs. It must be set
to
Off .
NOTE: Only indicated for heat pump A1.
