Maximum Temperature Thermostat

If the secondary supply temperature detected by maximum thermostat he becomes too high, the heat exchanger control and the primary pump will be stopped immediately. The secondary pump will continue to run to dissipate the excessive heat into the secondary system.

NOTE:

The temperature setpoint of the thermostat must be higher than the value of the anti-legionella setpoint of the domestic hot water control. Otherwise the anti-legionella function does work properly.
