From the manufacturer's datasheet for WRF06 LCD RC RS485 Modbus.
Overview
The WRF06 LCD RC is a flush-mounted room operating unit for individual temperature control in living rooms, hotel rooms and offices. Four push buttons and an LCD show and set the temperature, fan stage and occupancy. It connects to an RS485 Modbus network and has an integrated controller. Versions add four digital inputs (DI4), two 0 to 10 V outputs (AO2V) that can drive proportional valves directly, two relay outputs (DO2R), two triac outputs (DO2T) or the OVR and OVT output extensions. The unit takes frames from Berker, Busch-Jaeger, Feller, Gira, Jung, Merten and Peha, which are specified when ordering. Removable terminals allow pre-wiring.
