General

The WS9 Series wall module is a temperature control device with an LCD display designed on the basis of the standard 86 wall-mount installation box. The units feature Modbus communications, monitor the actual room temperature and the set temperature in real time to control the opening/ closing of the valves in the fan coil units to regulate the room temperature. The WS9 Series wall modules provide anti-freeze protection, as well as manual and automatic fan speed control. The WS9 Series wall modules work with fan coil units and regulate the room temperature by controlling the fan speed and the opening/closing of the valves. The modules usually work with the fan coil unit control valves.
