>> Anti-seizure mode

>>> Day of the week

>>> 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.

Table 114 Anti-seizure start time

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.

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.

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.
