CRCT230 Range of
Electronic Room Thermostats
with Function Switches
Features
CRCT230CO1 C01
• Wide range of application options
• Compact design
• Electronic accuracy
• Wallplate construction
• LED status indicators
This range of thermostats is aimed primarily at the
heating and air conditioning market, where there
is a demand for enhanced functionality. All models
feature diff erent combinations of supplementary
function switches which are accessible to the
user.
CRCT230LS: This thermostat, which can be used
in either heating or cooling systems, incorporates
a manual switch which allows the thermostat
output to be switched off .
CRCT230C3: Designed for use with cooling only
fan coil units, the CRCT230C3 incorporates a
combined system isolation switch and Fan Auto/
Fan Continuous switch. The latter allows the user
to decide if the fan should run continuously or
only when there is a demand for cooling. A second
three position switch allows the user to select one
of three fan speed settings.
CRCT230CO3
CRCT230CO1: Designed for use in twopipe changeover fan coil unit systems, the
CRCT230CO1 incorporates a single speed fan as
well as manual Heating/Cooling (Winter/Summer)
switch which allows the thermostat to operate as
a cooling thermostat in the summer and a heating
thermostat in the winter. A second two position
switch allows the user to turn the thermostat
output off and set the fan to either manual or
automatic mode if so desired.
CRCT230CO3: Designed for use in two-pipe
changeover fan coil unit systems, the CRCT230CO3
incorporates a manual Heating/Off /Cooling
(Winter/Off /Summer) switch which allows the
thermostat to operate as a cooling thermostat
in the summer and a heating thermostat in the
winter. A second three position switch allows the
user to select one of three fan speed settings.
CRCT230H3: Designed for use with heating only
fan coil units, the CRCT230H3 incorporates a
combined system isolation switch and Fan Auto/
Fan Continuous switch. The latter allows the user
to decide if the fan should run continuously or
only when there is a demand for cooling. A second
three position switch allows the user to select one
of three fan speed settings.
