What to do if ...?

• the radiator does not get warm?

Check whether...

... the ON/OFF button1) is switched on.

... the appropriate fuse in your fuse box has been connected or the residual current circuit breaker has switched off.

... the thermostatic valve has been opened.

... there is too much air in the heater. Bleed the heater via the air bleed 25k (

Remove the cause!

If the heater still does not warm up, call a qualified installer.

Switch the radiator off and then on:

– the LED indicator "appliance heating up" flashes 3 times, the measuring probe is damaged.

Call a qualified installer.

— the LED indicator "appliance heating up" flashes 5 times, the mains voltage to the appliance is too high.

Switch the heating element off. Call a qualified installer.

• the rapid heater switches off too early?

Check whether the dust filter (11) and/or air exit grill on the rapid heater is obstructed.

If necessary, clean them. (see part 1.5)

If the room temperature is too high, the rapid heater automatically switches off early for safety reasons, in order to avoid damage. Above 1000 metres above mean sea level, this may occur repeatedly because of the thinner air, which means that the air heats up more quickly.

In each case, take the following steps to restart the appliance::

-switch off the appliance by means of the ON/OFF button;

—wait at least 10 minutes before switching on the appliance again.

- when the sevice technician has been called?

Inform the service technician about the type of unit (Typ) and it's number (Nr.) that is found on the rating plate (27)!
