The pressure regulator interrupts the circuit for the heating
if the specified steam pressure is reached in the pressure
tank.
If the pressure in the pressure tank falls again, i.e. the
steam has been consumed, the pressure switch automati-
cally closes the circuit.
The pressure switch has 3 connections:
COM = Masse (earth,ground))
NO = normaly opened
NC = normaly closed
The pressure regulator is connected to the terminals COM
and NC.
The safety lock is an additional safety element in the pres-
sure tank lock.
It opens, if the pressure regulator is defective.
If the safety lock has opened, the pressure regulator must
be checked in order to detect why it has not functioned.
