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.
This manual describes the purpose and features of the RDF310 and RDF410 room temperature controllers, which are used for single‑zone heating or cooling with three‑speed fan control, manual or automatic mode switching, and infrared remote operation. It includes details on temperature sensing, programmable time periods, and parameter settings for heating, cooling and standby modes.
Installation instructions cover wiring, power supply (AC 230 V), mounting in an embedded junction box, and connection to valves, actuators and compressors. The document also provides fault handling, parameter adjustment procedures, and ordering information for accessories such as the IRA210 remote control. This manual is written in Chinese.
