> Circulation pumps
>> Heating circuit pump G1
>>> Operation alternative
B Select if circulation pump G1 should run continuously or in optimised
operation. The setting applies to G1 of all circuits.
Continuous means that G1 is always in operation during the heating
season.
Automatic means that the circulation pump runs in approx. 10 min,
stands idle for 10 min, and so on, if it is in winter operation and there
has not been any heating demand for 40 min. Automatic operation is
cancelled when heating demand arises or winter operation is
disabled.
G1 stands idle (apart from anti-seizure operation) if it is summer
operation.
>> Heat carrier pump G2
>>> Operation alternative
B Select if heat carrier pump G2 should run continuously or start
automatically when the compressor starts.
The setting applies to all heat pumps' G2. In automatic operation, G2
starts for heat pump 2 when compressor 2 starts.
>>> Pump speed E2x
>>>> Fixed pump speed
B Set desired percentage to maintain a constant pump speed. Auto
means the pump speed will be controlled by the control unit.
>>>> Temperature difference heat transfer fluid when heating
B Specify the temperature difference which the heat pump will aim to
achieve. This is done by regulating the pump speed.
>>>> Temperature difference heat transfer fluid when hot water
B Specify the temperature difference which the heat pump will aim to
achieve. This is done by regulating the pump speed.
>>>> Pump speed at no demand
B Set pump speed when there is no demand. A low speed is used to
keep the system operating when there is no demand for heat.
>>> Regulator settings
>>>> P constant
>>>> I constant
>> Collector circuit pump G3
>>> Operation alternative
B Select if collector circuit pump G3 should run simultaneously with the
compressor or continuously.
16.8 Additional heat
The additional heat works together with the heat pump to maintain the
right heating in the circuits. The additional heat can be selected to work
alone.
Under Additional heat, there are:
• Additional heat general
• Electric additional heat
• Hot water electric heater
• Additional heat program
> Additional heat general
Under Additional heat general the functions that are common to
electric additional heat and mixed additional heat are found.
>> Start delay
B Set what start delay should apply to the additional heat.
When the need for additional heat arises, a timer with set time is
started. When this time has passed the additional heat starts.
>> Additional heat only
B Change to Yes if the additional heat should work alone.
This can be suitable if the heat pump should provide heat before, e.g.,
the collector circuit is ready.
