1. GENERAL FEATURES
thTx is the CAREL room thermostat for residential or commercial
environments, off ering an easy-to-use interface.
The temperature is set simply and intuitively using the arrows on the
touch keypad. The compact dimensions and elegant design make it
suitable for any type of environment, as well as being ideal both as a user
interface (HMI) for heat pumps, rooftop units, AHUs, fan coils, etc., and as a
zone control display for centralised systems. The RS485 serial connection
via Modbus ® protocol can manage multiple thTx devices connected to
the same programmable controller, for synergistic control. The thermostat
can work in stand-alone mode as a room thermostat, or can be connected
to programmable controllers for zone management in radiant systems.
Depending on the model, it can be equipped with a temperature probe
or a temperature and humidity probe, and is available with 230 Vac or 24
Vac/Vdc power supply. thTx can also manage a three-speed fan.

Installation warnings
• The thTx thermostats have been designed for fl ush mounting, in wall

the rear part to make the electrical connections.
Notice: the thermostat should be installed indoors, at a height of
approximately 1.5 m above the fl oor, in a place representing the average
room temperature. It should be away from direct sunlight, any coverings
or any heat source, to avoid false readings for temperature control.
