The operating principle of the AIRTRONIC B4.
When enabled, the control lamp in the control lights up. The glow plug is turned on and the fan runs at low speed.
After 65 seconds, the fuel supply starts and the air-fuel mixture ignites in the combustion chamber.
After 60 seconds after the detection by the combined sensor (combustion sensor) of the presence of flame, the pin electrode of the filament is disconnected. After that, the unit is in the normal operation mode.
In heating mode, the room temperature or the temperature of the intake air is constantly measured.
If the temperature is higher than the value set on the control panel, the regulation starts.
There are 4 stages of regulation, which ensures precise adjustment of the heat energy flow supplied by the heating device in accordance with the needs. The speed of the fan and the amount of fuel supplied correspond with the selected control stage.
If the temperature is exceeded even at the lowest control stage, the heater goes to the "OFF" control stage with the inertial fan run for about 4 minutes for cooling. Then the fan runs until the next start at minimum speed (recirculation mode) or turns off (fresh air mode).
When the heater is switched off, the test lamp goes out and the fuel supply is cut off.
For cooling, the inertial run-out of the fan is provided for about 4 minutes. To clean the combustion chamber during the inertial run-out of the fan, a pinning electrode is turned on for about 40 seconds.
Special situation: If the fuel supply does not occur before shutdown or if the heater is located in the "OFF" stage, the heater goes into standby after the inertial run-out.
