Heater safety thermostat triggered
Cause:
Thermostat trips during operating mode with heater. The FAM
goes into the after-running phase and switches off.
This error message can be connected with a preceding error
message and with the immediate switch-off of the FAM that

Resetting:
Allow the heater to cool down before performing a Reset.
Undo the 4 screws and remove the cover from the heater
terminal box.
To reset the heater, press down the red button (B) so that it
engages in the lower position.
The mechanism is tripped by a bi-metal. This bi-metal must
first cool down in order to recover. The cooling phase can
indeed take up to 2 hours, depending on ambient conditions.
