26. Heater safety thermostat triggered
Cause:
Thermostat trips during operating mode with heater. The FAM
goes into the after-running phase and switches off.
If an operating mode is selected for which no heater is
switched on, then it is possible to operate the FAM. The
message will however be displayed and can be reduced with
ESC. If the FAM is in Automatic mode and a switchover to an
operating mode with a heater is carried out while the
thermostat is still tripped, then the FAM will go into the after-
running phase and switch off.
This error message can be connected with a preceding error
message and with the immediate switch-off of the FAM that
takes place as a result..
Resetting:
Allow the heater to cool down before resetting.
Undo the 4 screws and remove the cover from the heater
terminal box.
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.
