4. General description The controller is used to manage a radiant panel heating or cooling system. The MASTER controller receives the information from the SLAVE controllers. The communication between the MASTER controller and the SLAVE controllers may be performed in 2 ways: contact communication, communication through Modbus RTU protocol.

• MODBUS connection diagram These diagrams refer to the FH-xMxSH1 models. The RS485-MODBUS line has a long main bus to which the appliances are connected directly (max 31 SLAVE appli- ances with 1 MASTER appliance). Use cables with a braided pair + 1 ground wire + shield. Use the braided pair to connect A+ and B- and the single wire for GND which must be connected to each device.
