actUatIoN board
This board (see fig. 36) is intended to activate the 120
V~ users through relays. Moreover, it can manage the
signals from the cams and/or microswitches on the vari-
ous users and control the boiler board.
the board is supplied at 24Vac.
the software intended to manage the board is directly
loaded onto the microprocessor (by means of rs232 or
UpKey onto the CPU).
- the green LED (2) is flashing on and off during the nor -
mal operation of the board;
- the yellow LED (6) is signalling that 5 Vdc is applied.
- the red LED (3) is on during the reset of the board
- the red LED (10) is signalling the operation status of
the boiler heating element (some models).
