Pressure Switch and Overheat protection

Pressure switch and overheat protection are only in heat
pump module with integrated electrical supplement.
Overheat protection must be manually reset if it trips.
The pressure switch and overheat protection are
connected in series, triggered alarm or information in
the controll unit means either low pressure in the system
or to high temperature in the additional heater.
If the pressure switch has tripped resets itself when the pressure is
sufficient in the system.

heating system by adding water to the filling valve to a maximum of 2
bar.
