Measures when safety device is on
Hot Water Temperature Sensor
Failure
Disconnection or short circuit of hot water temperature
sensor
Poor detection during ignition
Re-ignition failure during combustion
Primary overheat protector failure

Hot water temperature increase over the limit
Poor signal from hall sensor
Supply fan or sensor failure
Room temperature sensor failure
Disconnection or internal short circuit of room
temperature sensor
Disconnection or short circuit of electronic gas valve
Heating temperature sensor failure
Disconnection or short circuit of heating temperature
sensor
Boiling safety device for heating
Heating water temperature 95°C
Outdoor thermostat failure
Disconnection or short circuit of sensor
Residual flame detection (quasi-
flame)
Residual flame or flame sensor failure in the combustion
chamber before or after activation
Communication failure between main circuit boards
Wind pressure switch (counter-
pressure safety device activated)
