4. Instal·lació
4.1 Abans de començar
- Ensure power to the heating circuit is OFF at the main electrical panel.
- Confirm the thermostat's ratings match your heating system's requirements.
- Gather necessary tools: screwdriver, wire strippers, electrical tape, voltage provador.
4.2 Muntatge
The thermostat is designed for wall mounting. It should be installed on an electrical box at approximately 5 feet (1.5 meters) from the floor, on an inside wall. Avoid locations near windows, doors, or heat sources that could affect temperature readings.

4.3 Cablejat
WARNING: Risk of electric shock. Installation must be performed by a qualified electrician.
- Assegureu-vos que l'alimentació estigui DESCONNECTADA a l'interruptor principal.
- Connect the thermostat wires to the heating system's supply wires and heater wires according to the wiring diagram provided with your specific heating unit and local electrical codes. The SWT2F is a double pole thermostat and will have four wires for connection (two for line input, two for load output).
- Secure all wire connections with appropriate wire connectors.
- Carefully push the wires back into the electrical box and mount the thermostat to the wall box.
- Restableix el subministrament elèctric al quadre elèctric principal.
5. Funcionament
5.1 Configuració de la temperatura
The Stelpro SWT2F thermostat features a simple rotary dial for temperature adjustment:
- Ajust: Rotate the dial clockwise to increase the desired temperature and counter-clockwise to decrease it. The temperature scale ranges from 50°F to 90°F.
- Posició OFF: For complete power disconnection to the heater, turn the dial fully counter-clockwise past the 50°F mark to the 'OFF' position (indicated by a snowflake symbol). This feature is specific to double pole models like the SWT2F.
- Fluctuació de la temperatura: The thermostat operates with a 4°F set point, meaning the room temperature may fluctuate within approximately 4°F of your desired setting before the heating system activates or deactivates. This is normal operation to prevent rapid cycling.

6. Manteniment
The Stelpro SWT2F thermostat requires minimal maintenance:
- Neteja: Netegeu periòdicament l'exterior del termòstat amb un drap suau i sec.amp tela. No utilitzeu netejadors abrasius ni dissolvents.
- Sense peces reparables per l'usuari: The thermostat contains no user-serviceable parts. Do not attempt to open or repair the unit.
- Flux d'aire clar: Ensure that the thermostat's vents (if any) are not obstructed by dust or objects, as this can affect temperature sensing accuracy.

Consulteu la taula següent per veure els problemes habituals i les seves possibles solucions:
| Problema | Causa possible | Solució |
|---|---|---|
| L'escalfador no s'encén. | Thermostat set to 'OFF' or too low. No power to the circuit. Faulty wiring. | Turn dial to a higher temperature. Check circuit breaker. Verify wiring connections (consult electrician). |
| Heater not turning off. | Thermostat set too high. Thermostat malfunction. | Turn dial to a lower temperature or 'OFF'. If problem persists, consult electrician or replace thermostat. |
| Lectura de temperatura inexacta. | Thermostat located near draft or heat source. Normal temperature fluctuation (4°F hysteresis). | Relocate thermostat if possible. Understand that minor fluctuations are normal. |
| Thermostat feels warm. | Normal operation due to electrical current passing through. | This is generally normal. If it feels excessively hot or emits smoke/smell, disconnect power immediately and consult an electrician. |
