Maximum Temperature Safety Function

If the domestic hot water temperature, detected by the maximum thermostat, becomes too high, the charging pump will be stopped and the circulation pump will start without delay if the parameter SEP-04 takes one of the values 2 or 4.

NOTE:

The temperature setpoint of this thermostat must be higher than the value of the anti-legionella function setpoint. Otherwise the anti-legionella function does not work properly.
