COMPUTHERM T-32 Digital Room Thermostat User Manual

1. Introducció

The COMPUTHERM T-32 room thermostat is designed for controlling most boilers and air conditioners available in the EU. It can be easily connected to any gas boiler with a two-wire thermostatic connection point, and to all air conditioning systems or electrical appliances, whether they have a 24V or 230V control circuit.

This digital thermostat allows for more precise temperature measurement and adjustment compared to traditional thermostats. It helps reduce energy costs while maintaining comfort by regulating the connected appliance (e.g., a gas boiler or pump) based on the measured and set temperatures.

Característiques principals:

• Control precís de la temperatura: Easily set desired temperature between 5°C and 30°C in 0.5°C increments.
• Constant Indoor Temperature: Switching sensitivity of ±0.2°C or 0.1°C ensures a uniform and stable room temperature.
• Compatibilitat versàtil: Suitable for boilers with a two-wire connection and various HVAC systems (24V or 230V).
• Modes de calefacció i refrigeració: Supports both heating and cooling functions.
• Pantalla digital: Provides clear and accurate temperature readings.

2. Configuració i instal·lació

2. Insert the two AAA batteries into the battery compartment, ensuring correct polarity (+/-).
3. Torneu a col·locar la tapa posterior.

2.3 Muntatge i cablejat

The thermostat is designed for wall mounting in a room. Choose a location away from direct sunlight, drafts, or heat sources that could affect temperature readings.

1. Separate the front panel from the back plate.
2. Marqueu la posició de muntatge desitjada a la paret.
3. Perfora forats i insereix els tacs de paret.
4. Fixeu la placa posterior a la paret amb els cargols proporcionats.
5. Connect the two-wire control circuit from your boiler or HVAC system to the terminals on the back plate. Refer to the wiring diagram on the back of the thermostat for correct connections.
6. Carefully reattach the front panel to the back plate.

3. Funcionament

3.1 Mostra finalview

The digital display shows the current room temperature and the set desired temperature. The thermostat features three control buttons below the display.

3.2 Configuració de la temperatura desitjada

Use the temperature control buttons (typically marked with up and down arrows or similar symbols) to adjust the desired temperature. Each press changes the temperature by 0.5°C within a range of 5°C to 30°C.

• Premeu el botó Fletxa amunt botó per augmentar la temperatura desitjada.
• Premeu el botó Fletxa cap avall botó per disminuir la temperatura desitjada.

The thermostat will automatically regulate the connected heating or cooling appliance to maintain the set temperature within its switching sensitivity of ±0.2°C.

3.3 Heating Mode Operation

In heating mode, if the measured room temperature falls below the set temperature minus the switching sensitivity (e.g., 22°C - 0.2°C = 21.8°C), the thermostat will activate the heating appliance. It will deactivate the heating when the room temperature rises above the set temperature plus the switching sensitivity (e.g., 22°C + 0.2°C = 22.2°C).

3.4 Cooling Mode Operation

In cooling mode, the operation is reversed. If the measured room temperature rises above the set temperature plus the switching sensitivity, the thermostat will activate the cooling appliance. It will deactivate cooling when the room temperature falls below the set temperature minus the switching sensitivity.

Note: After a temperature change using the thermostat's adjustment buttons, the switching sensitivity is temporarily not considered, allowing the thermostat to react to a difference of ±0.1°C for immediate response.

4. Manteniment

• Neteja: Netegeu el termòstat amb un drap suau i sec. No utilitzeu productes de neteja abrasius ni dissolvents.
• Substitució de la bateria: Replace batteries when the low battery indicator appears on the display. Always use new AAA alkaline batteries.
• Eviteu les obstruccions: Ensure no objects block the thermostat's ventilation slots or sensor, as this can affect temperature accuracy.
