RET230 HC



- Stylish modern design
- For use in 4-pipe fan-coil systems
- Large setting dial with LCD temperature display
- 230 volt operation
- On/Off or chrono-proportional regulation


The RET230 HC-3 is a heat/cool room thermostat designed for use in either a 2-pipe or 4-pipe fan-coil systems. This flexible and versatile thermostat incorporates many enhanced features.

The RET230 HC-3 incorporates an analogue setting dial, scaled 1 to 5, plus a small LCD display which normally displays actual room temperature, but changes momentarily to show the set temperature when the setting dial is moved.

In addition to the heating and cooling outputs, the thermostats incorporates a fan relay to control the operation of a single phase 3-speed fan motor. A manual switch on the right of the thermostat allows the user to manually select the required fan speed. An additional manual switch on the left allows the user to turn off the thermostat and to select whether the fan is switched on or off with the heating/cooling output or runs continuously. LED indicators provide clear indication of output status.

In addition to providing conventional on/off control, the thermostat can be set up at time of installation to provide chrono-proportional output. This type of control mode provides closer control accuracy compared to on/off control.
