Connecting the room thermostat

 CAUTION

To avoid damage to the heater, please observe 

the following:

–   Provide post-cooling for the heater. The heater 

requires a continuous supply of 230 V AC, 
50 Hz.

–   In case of a power failure, an emergency power 

supply unit should automatically take over the 
power supply. Emergency power supply units 
with a cardan shaft drive for tractor attachment 
are also suitable.

 

Use a room thermostat with a hysteresis of ± 1°C. 
It switches on if the room temperature is 1°C 
less than the set temperature and switches off 
again once the room temperature is 1°C more 
than the set temperature.

 

The floating connectors X4 (230 V) or X8 (24 V) 

are used to connect the room thermostat.

 

If the room thermostat is connected to the mains 
supply of other connectors (connector X1 or X3), 
the heater will be damaged.
