A restarting lockout prevents
the burner from being restarted.
The reset button (RESET) must

triple function combination
controller
The triple function combination
controller has a sensor monitor
and is cold resistant to -20°C.
The heater switches off at a tem-
perature below -20°C and switches
on again when the temperature
rises.
In the event of damage to the sen-
sor or capillary tube and on reach-
ing a temperature of about 220°C,
the filling medium is drained and
the combination controller switch-
es off towards the safety side. The
combination controller is no longer
functional and must be replaced.
For replacement of the triple func-
tion combination controller, the
following information must also
be observed:
■
The capillary tubes must not
be damaged or bent during
installation.
■
Any bending must take place
only on the capillary tube and
not on the sensor.
■
To ensure that the heater func-
tions reliably, the sensors must
always lie freely in the hot air
stream.
■
The sensors must always be
free of dust and dirt.
■
Capillary tubes and sensors
must not be damaged in any
way.
■
The sensors must not have
contact with the combustion
chamber or other metal parts.
