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.
