From the manufacturer's datasheet for LCF02 active.
Overview
The LCF02 is a room thermostat for 2-pipe and 4-pipe fan coil units. It controls modulating valves by PWM or 0 to 10 V, and fan speeds by three relay stages or 0 to 10 V. The 6WV version is set up for a 6-way control valve. It has a 64 x 41 mm backlit display and five buttons for setpoint and fan stage. Two inputs take occupancy, window contact, dew point or changeover signals, and an extra input takes an external room temperature sensor. An RS485 Modbus interface lets a supervisor override the control parameters. It mounts flush in a standard 60 mm EU box at least 45 mm deep.
