Table 114 Anti-seizure start time
▶ Set date and time for anti-seizure operation.
Anti-seizure mode ensures that components do not become seized
during periods of inactivity.
Anti-seizure mode operates differently in summer and in winter. This
enables the duration of the anti-seizure operation to be reduced.
Furthermore, during anti-seizure operation the entire system does not
need to be switched off in winter.
Anti-seizure mode in summer mode
Anti-seizure mode starts only if there is no other type of
demand. When there is a demand, the anti-seizure
operation waits for up to one hour for the demand to be
satisfied. Otherwise, the anti-seizure operation has to
wait until the next period.
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 a 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.
Anti-seizure mode in winter mode
In winter mode, anti-seizure operation only operates on
valves, mixers and pumps that normally do not operate
in winter mode (refers to accessories such as pool and
solar). Anti-seizure mode can occur during operation.

>> Operating mode
▶ For a description of operating modes ( Chapter 8.4).
The set operating mode is indicated with the symbol >
before the selected mode. Operating mode is selected
automatically the first time the heat pump is started.
Operating mode can be changed here. The control unit
allows only the options that can be achieved with the
installed equipment.
Selection of operating mode leads to automatic setting
of certain values in the control unit.
