8.1 Supervisor variable list
The interface to an RS485 supervisor network using the Carel/Modbus
protocol with a maximum baud rate of 19200 bps requires installation
of the optional opto-isolated card PCOS004850 and the plastic support
PCOS00S030 that fixes the optional card to the electronic control board
slot on the “Main” electrical panel board.
The serial line is configured by default with the following parameters:
• address 1
• baud rate 19200 bps
• frame 8, N, 2 (not modifiable)
It is recommended to not set any variables that are not shown in the
table, even if they are visible on the supervisor, so as to not risk comprising
correct humidifier operation.
