3. Setup
3.1. Installazione
The COMPUTHERM Q20 thermostat is designed for easy connection to most heating, cooling, humidifying, or dehumidifying devices. It requires a two-wire thermostatic connection and is compatible with both 24V and 230V control circuits.
- Disconnection d'energia: Before beginning installation, ensure that the main power supply to your heating/cooling system is turned off to prevent electrical shock.
- Muntamentu: Mount the thermostat in a central location in the room, away from direct sunlight, drafts, or heat sources that could affect temperature readings.
- cablaggio: Connect the two control wires from your heating/cooling system to the appropriate terminals on the back of the Q20 thermostat. Refer to the wiring diagram provided with your specific heating/cooling appliance for correct terminal identification.
- Installazione di batterie: The thermostat requires 2 AA batteries for operation. Insert them into the battery compartment located on the back of the unit, observing correct polarity.
- Restaurazione di l'energia: Once wiring and battery installation are complete, restore power to your heating/cooling system.

3.2. Configurazione iniziale
Upon first power-up or after battery replacement, the thermostat may require initial setup. This typically involves setting the current time and day, and calibrating the temperature and humidity sensors if necessary.
- Time and Day Setting: Use the programming button (calendar icon) and up/down arrows to set the correct time and day of the week.
- Calibrazione di u sensoru: The temperature sensor can be calibrated within a range of ±3 °C (0.1 °C increments) or ±6 °F (0.1 °F increments). Consult the full product manual for detailed calibration steps.
- Selezzione di u modu di funziunamentu: Use the operating mode button (arrows icon) to switch between heating, cooling, humidifying, and dehumidifying modes.
