The properly installed appliance according to the control sign received from temperature regulator - in the present case heating – starts
the exhaust fan,which executes the 30 seconds prepurge time. This time period is also enough for biggest power appliance to ensure
the satisfactory air exchange namely the triple of combustion air volume. When the ventilation happened the sparking is started and the
dual magnetic valves are opened the gas ignites.
If the continuous burning is formed within 5-10 seconds the appliance is operating normally the green control lamp is lighting..During
operation the appliance continuously monitors the status/sign of diff erential pressure switch and fl ame detector, if needed the electronic
control intervenes in the process.
If the status of diff erential air pressure switch is changed during operation namely switches over from work/switched on position to ba-
sic/standstill position in that case the automatic electronic control stops the gas supply by closing of magnetic valves and controls the
appliance in error mode moreover the red control lamp located on front side of device is lighting.
In case the fl ame detector of automatic burner control does not sense fl ame formation during ignition in that case stops the gas supply
and controls the appliance in error mode moreover the red control lamp is lighting.
In case during burning process the pressure diff erence decreases under the permissible minimal value on the air pressure switch than
the automatic control prohibits the operation as follows:
• stops the gas supply
• stops the operation of exhaust fan
• controls the appliance in error mode and red control lamp is lighting
ATTENTION! The restart of appliance, which is in safety status can only be possible by
pushing of „RESET” push button located on the PCB (inside of appliance) or on the tem-
perature regulator!
General information:
The fl ame detector is self-checking and can just operate with the burner, other environmental eff ects (ambient
temperature,lights) can not infl uence it.
