Resetting the safety thermostat
The safety thermostat is triggered when the boiler
temperature exceeds 100°C and blocks the fan. The
pumps enabled according to the type of diagrams will
continue working.
IMPORTANT: The reset control of the FIREX boiler
safety thermostat is located on the left of the panel
board.
The thermostat resets operation of the wood-fired
boiler.
To access it when the boiler blocks, unscrew the plas-
tic cap with a screwdriver; after resetting the boiler,
put the plastic cap back on.
The safety thermostat can be triggered when the boiler
overheats. This can be solved first of all by lowering the
operating temperature of the boiler (see next point).
If the room thermostat is not requesting the words WINT
OFF WOOD COMB. are displayed, or if there is no demand
for DHW the words SUMMER OFF WOOD COMB.
In Summer mode, the heating system pump is disabled.
