2. How to stop the heater
Set main switch to pos. "0".
If the heater has been running on position "Heating" (Heizen) it has an automatic
cooling of the heater until it completely shuts off.
Important!
Pull the main plug only after the heater has cooled down and stopped.
Before repairing or servicing always pull the main plug.
On operation "Ventilation" (Lüften) the unit shuts off immediately.
3. Safety and control devices
In case there is no flame - for example caused by lack of fuel - the oil burner relay
shuts off the heater. The control lamp on the side of the burner reset button lights up.
After the cause of the malfunction has been cleared the reset button can be pushed
after a waiting time of appr. 60 sec. and the burner can be restarted.
Combi control
The combi control is equipped with 3 temperature sensors which are straight in the
warm air stream.
The first sensor controls the starting retardation and the postpurge of the fan.
The second sensor controls the operation temperature. If the max. operating
temperature of 80° C is exceeded, the sensor shuts the burner off while the fan
continues to run for cooling.
The third sensor serves as a safety thermostat against overheating, for example in
case of malfunction of the fan.
After the cause of overheating has been eliminated the reset button of the safety
thermostat has to be pushed in order to restart the heater.
Room thermostat
The thermostat has a temperature regulation range of 5° C - 30° C and shuts the
burner off after the preset temperature has been reached. The fan continues to run
in order to cool the heater down to a temperature of appr. 30° C before it stops. After
the room temperature drops several °C the heater automatically starts running again.
4. Transport
The heater can be transported and is equipped with hooks for crane transportation.
These hooks are especially marked. Please use only these devices.
5. Cleaning
The heater should be cleaned minimum once a year. Therefore remove the lid of the
