10.3.4.2. Configuring Controllers for Superheat and Suction Mode
To configure the controller as a master in the Superheat and Suction mode, the following parameters must be set:
Note that if the Modbus address or baud rate is changed, the controller must be rebooted
.
To configure the controller as a slave case controller in a lineup where the master controller is Superheat and Suction mode, the following
parameters must be set:
