CONNECTION TO A SUPERVISION SYSTEM
(units with mP20 control only) With the addition of a serial circuit, the microprocessor control enables chiller
function to be controlled by a centralised supervision system.
For the connection of the control to the supervision systems, an optional serial board enables opto-isolated
interface with a standard RS422 network for the transmission of unit data at 1.2 kByte/s. Alternatively a
shielded 2-core telephone cable can be used for RS485 communication at 19.2 kByte/s.
The MODBUS communication protocol used enables connection with all the main supervision systems
