Possible solutions
Check circulator pump
Unlock the safety temperature limiter
(info see 4.3)
Clean heat-exchanger,
clean burn pot, air sensor
Check flue-gas fan, rpm sensor
Check fuel supply
Check pellets (length),
inspect combustion chamber temperature
sensor
Check that heat radiation possible at the back,
replace the circuit board
