CPU ACTIVATION BOARD
The board provides for activating the users via relay.
It manages the signals originating from the cams and/or
microswitches and controls the 24Vdc users.
It also controls the relays operating the boilers.
The board is 24 Vdc powered and is positioned on the
adjustable support
The board management software is loaded directly on
the microprocessor.
On the board are the relays; the table below indicates
the users activated by relay.
Refer to the wiring diagram of the device.
