Safety Devices

Safety devices serve for the protection of
the user and must not be put out of opera-
tion or bypassed with respect to their func-
tion.

Pressure controller

The pressure controller keeps the boiler
pressure during the operation as constant
as possible. The heating is turned off if the
maximum operating pressure of 4 bar is
reached in the boiler and is reactivated in
case of a pressure drop in the boiler due to
steam tapping.
Water shortage thermostat
When the water in the boiler becomes ex-
hausted, the temperature of the heating in-
creases. The low-water thermostat turns off
the heating, and the red low-water indicator
lamp "water shortage" lights up. The heat-
ing is prevented from being turned on again
until the boiler has cooled down or been re-
filled with water.
