RDF310.2 and RDF410.21 are embedded room thermostats with LCD display, designed for single-cooling or single-heating systems. They can be used to control the temperature of single rooms and areas, which are heated and cooled by two-pipe fan coil units or single-stage compressor direct expansion devices. The controller controls a three-speed fan, a water valve actuator in two-pipe or a single-stage compressor in direct expansion devices. The thermostat acquires room temperature via an integrated sensor and maintains the set temperature by outputting a switching signal to control the valve or compressor.
