ThT Thermostat is the CAREL room thermostat that allows users to control the temperature in residential or light commercial environments, providing of simplifi ed interface that is ideal for end users. Temperature set is simple and intuitive, using the knob on the front panel. thT also allows the user to make some settings, such as the operating mode and time bands. Compact dimensions and elegant design make it suitable forall types of rooms, as well as being ideal both as a simplifi ed HMI (HumanUnit Interface) for heat pumps, rooftop units, AHUs, etc. and as zone controller display for centralised systems.The RS485 serial connection over Modbus® protocol means architecture can be implemented in which multiple displays are connected to a controller to create synergic control logic with programmable controllers.It can works in stand–alone mode as ambient thermostat or connected to programmable controllers.Depending on the model, thT thermostat is fi tted for Flush or Wall mounting and power supply is 230 Vac.A temperature sensor is available in all models in order to manage the comfort in the residential ambient, and a Humidity sensor only on specifi c models.thT is compatible with the main fl ush mount distribution boxes availableon the market.

• These thT thermostats have been designed for wall or fl ush mount assembly, on distribution boxes compliant with the standards in force;
• before performing any operations on the thermostat, disconnect the power supply from the device by switching the main switch on the electrical panel OFF. Then remove the front part of the thermostat from the rear to make the electrical connections;8 “manuale thT” +0300077IE - rel. 1.3 - 11.04.2016 ENG

• for the serial connection use three-wire shielded cable, AWG 20-22. The length of the network must not exceed 500 m. For extended networks fi t a 120 Ohm resistor between RX/TX+ and RX/TX- on the fi rst and last device, to avoid possible communication problems.Assembly for the fl ush mountingTo fi t the rear part of the terminal use a fl ush mount box with a min. diameter of 65 mm and a minimum depth of 31 mm.1. Detach the front from the rear of the thT thermostat using a screwdriver;2. Make the electrical connections according with the schematic; 3. Fasten the rear to the fl ush mount box using the 2 screws supplied:4. Finally reposition the thT thermostat the original position and ensure to fi x it with clicks into place.DismantlingWiring GND Rx+/Tx+Rx–/Tx– GND

General notes Avoid installing the terminal in environments with the following characteristics:

• relative humidity greater than the value specifi ed;

• strong vibrations or knocks;

• exposure to water sprays;

• exposure to aggressive and polluting atmospheres (e.g.: sulphur and ammonia fumes, saline mist, smoke) so as to avoid corrosion and/or oxidation;

• strong magnetic and/or radio frequency interference (for example, near transmitting antenna);

• exposure to direct sunlight or the elements in general;

• large and rapid fl uctuations in the room temperature;

• environments where explosives or mixes of fl ammable gases are present;

• exposure to dust (formation of corrosive patina with possible oxidation and reduction of insulation). Electrical connections
