SAFETY PRESSURE SWITCH
The safety pressure switch is triggered in case of operating pressure
switch fault and permanently stops the burner.
The pressure switch is equipped with a single-pole switch, of which
the position of the contact depends on the pressure on the relevant
connection and on the value set.
The safety pressure switch is set at a pressure higher than the operating
pressure switch setting, but always lower than safety valve opening value.
