Operation with room temperature controller
1. For operation with room thermometer, the cap fitted to the socket insert H of the unit must be
removed. Now the thermostat plug can be pushed into the unit socket. The cap must be fitted for
operation without room thermostat.
2. Set the room thermostat (special accessory) to the requested temperature. Now the unit operates
automatically and switches off when the room temperature set has been reached.
Safety in case of excessive temperature
All units have been fitted with a safety temperature switch (E). If the unit should overheat, this safety
element will trigger. Then the fault light D will be lit red. After a few minutes, you can release the
safety element again. By all means check the reason for the shutdown, and remove this before
starting up again. As long as you do not hear any slight cracking sounds of the STB during actuation,
the device is still too hot.
The DE 20 SH unit has another thermostat which checks the outlet temperature. If the temperature
exceeds 150 deg. C, the thermostat will switch off part of the heating automatically. When the
temperature returns to normal, the full heating output is switched back on. This protects the hot air
hose against damage caused by overheating and increases the service life.
At the point of control, this function causes a slight cracking in the unit.
This function protects the connected hot air hose against overheating.
