OFF Post-treatment coil not present
DIP 4
ON Recovery unit with heating coil + cooling coil
OFF Recovery unit with heating/cooling coil
DIP 5
ON Freecooling through alternation of the air ow
OFF Freecooling through bypass damper
DIP 6
ON Freecooling dierential with 5°C hysteresis
OFF Freecooling dierential with 2°C hysteresis
DIP 7
ON Dierential pressure switches present
OFF Dierential pressure switches not present
DIP 8
ON Activation dierential according to 3°C electric load
OFF Activation dierential according to 2°C electric load
2.5 SUPERVISION SERIAL
This adjustment standard requires the management of the RS485 serial with which they can be connected as slave to a modbus network. The communication parameters are:
— Modbus RTU
— Baud Rate 19200 bit/s
— Stop bits 2
— No Parity
The following modbus data can be read/written by a supervision system:
