Anti-seizure mode in summer mode
Anti-seizure mode in winter mode
>> Highest permitted flow temperature T1
> Operating mode
B For a description of operating modes (
Chapter 6.4).
> Groundwater
>> Groundwater
B Indicate if groundwater pump G33 exists or not.
G33 is normally run simultaneously with collector
circuit pump G3.
In the event of Yes:
>> Compressor start delay
B Indicate the delay that is required until the
groundwater circuit circulates. The compressor
should not start before this has taken place.
There will be no delay under certain circumstances.
Anti-seizure mode starts only if there is no
other type of demand. When there is a
demand, the anti-seizure operation waits for
one hour at the most for the demand to be
satisfied. Otherwise, the anti-seizure
operation has to wait until the next
occasion.
Heat pump 1 runs first followed by heat
pump 2, etc. 3-way valves and circulation
pumps are run for 1 minute and mixing
valves for the respective mixing valve's run
time + 10s. A pause of 30s is made between
components.
During anti-seizure mode, certain parts of
the heating system become hot for a short
period of time, which is completely normal.
The anti-seizure mode is not cancelled if hot
water demand arises during the anti-seizure
operation. The hot water temperature can
thereby fall. A suitable time for anti-seizure
operation is when the hot water
consumption is low, e.g., at night.
In winter mode, anti-seizure operation is
executed on valves, mixers and pumps that
normally do not operate in winter mode
(refers to accessories such as cooling, pool
and solar). Anti-seizure mode can occur
during operation.
