RAB31

RAB 31 is a room thermostat designed to control four-pipe fan-coil units. The thermostat is equipped with a heating/cooling manual switch and a 3-stage fan speed switch. It is suitable for use in combination with zone valves, fans or with thermoelectrically driven valves.

If the room temperature drops below the set point, the output contact for heating is activated. If the room temperature exceeds the set value, the output contact for cooling is switched on. The fan speed can be controlled in two ways, either manually (one of three speeds is set via a switch and the fan runs continuously) or automatically, where the fan starts when the thermostat is switched on. In this case, it is necessary to change the position of the jumper on the thermostat PCB before commissioning.
