MICROCONTROLLER BOARD (MAIN BOARD)
1
The main board operates on 230 VAC, 50 Hz and drives gas valve, fan, pump and (in monothermic
types) 3 way electric valve. Dynamic air pressure test takes place before every ignition cycle. Limit
thermostat ensures extra safety level. Flame in the burner is checked regularly.
The main board provides all the functionality and safety of the boiler. The board was cased by a
plastic casing, which was mounted on the gas valve. The functionality of the board is provided with
2 microcontrollers (low voltage and high voltage microcontroller).
The board can be divided in 2 part: low voltage side and high voltage side. Both side have a
microcontroller. There is continuous communication between microcontrollers. Numerous data is
sent from one side to the another for check and comparison.
