regulation

The RET230 HC-3 and HCW-3 are heat/

cool room thermostats designed for

2-pipe or 4-pipe fan-coil systems. These

thermostats feature an analogue setting

dial, scaled 1 to 5, 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 incorporate

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.

RET230 HC-3 and RET230 HCA-3

Designed for use in 4-pipe fan-coil unit

systems, split packaged systems and in

air to air heat-pump systems.

RET230 HCW-3

Designed for use in 2-pipe fan coil

unit systems with central changeover

between heating and cooling.
