Protective startup with consumer pumps
The consumer pumps (heating circuit pump, DHW charging pump, external load) are
deactivated, or stay deactivated, if the locking signal exceeds the relevant value.
Threshold value for heating circuit pump = 5%
Threshold value for DHW charging pump = 50%
Note!
If protective startup occurs during DHW charging with shifting DHW charging priority,
the locking signal for shifting priority is set to 100%. This ensures that the DHW
charging pump can be activated before the heating circuit pumps are put into
operation.
Protective startup with consumer mixing valves
When protective startup is activated, the consumers with mixing valve are restricted in
their heat consumption in accordance with the locking signal value.
The function can be deactivated.

Function is deactivated.
