BOARD FUNCTION:
from power PFC regulator stage keeps the V/Bus and generate all the necessary auxiliary power supply.
Controlled from digital card 15.14.415 ,permit to activate with relative electronic switch the input relè, the fan the gas valve .
Powering also R.F. ignition card 15.14.430. Direct and not modulate powering also to two small fan placed on bottom close to the
inverter power switch and on top of rack pcb.
LOCATION:
5th position on rack system from left, between the analogic card and water unit control card.
DISMANTLING NOTE:
remove the screw at base of plastic support, then extract the pcb and when accessible disconnect CN2.
NOTE:
the pc board is composed by a sandwich of two card fixed one to the other through pin strip. Pcb 15.14.42901 and
15.14.439 are not available separately, the code 15.18.034 include both pcb. A small fan is integrated in order to keep cooled
this pc board.
