perature in the central heating system-must not
exceed 82°. In electric-only version check, if the
radiator is properly filled with the heating agent.
Check if the head of the heating element is com-
pletely hidden. Release the screw at the back of

towards the radiator and secure the casing back
The heating element is working properly.
Disconnect the device from its electric supply, wait
for the radiator to cool down and turn it back on.
