1. Introduzione
The Stelpro SWT2F Double Pole Thermostat is designed for precise temperature control of electric heating systems operating between 120V and 277V, up to 22 amps. This manual provides essential information for the safe installation, operation, and maintenance of your thermostat. Please read these instructions thoroughly before beginning installation or use.
2. Informazioni sulla sicurezza
Per evitare lesioni personali o danni alla proprietà, osservare le seguenti precauzioni di sicurezza:
- Scollegare l'alimentazione: Always disconnect power to the heating system at the main electrical panel before installing or performing any maintenance on the thermostat.
- Elettricista qualificato: L'installazione deve essere eseguita da un elettricista qualificato, nel rispetto di tutti i codici elettrici locali e nazionali.
- Uso previsto: This thermostat is designed exclusively for controlling electric heating systems. Do not use it for other applications.
- Voltage e Ampera: Assicurarsi che il volume del termostatotage e amperage ratings (120-277V, 22A) are compatible with your heating system.
- Double Pole Disconnect: The SWT2F model provides a double pole disconnect, meaning it completely cuts power to both lines of the heating circuit when turned to the 'OFF' position, enhancing safety.
3. Caratteristiche del prodotto
The Stelpro SWT2F thermostat offers reliable and straightforward temperature control:
- Mechanical Dial: Easy-to-use rotary dial for setting desired temperature.
- Intervallo di temperatura: Regolabile da 50°F a 90°F (da 10°C a 32°C).
- Double Pole Design: Provides a complete power disconnect to the heater when set to 'OFF'.
- Compatibilità: Suitable for electric baseboards, fan-forced heaters, and commercial fan-forced heaters with a 120-277 Vac coil contactor.
- Design elegante: a basso profilofile white molded plastic housing blends with various decors.

4. Installazione
4.1 Prima di iniziare
- Ensure power to the heating circuit is OFF at the main electrical panel.
- Confirm the thermostat's ratings match your heating system's requirements.
- Raccogli gli strumenti necessari: cacciavite, spelafili, nastro isolante, voltagetester.
4.2 Montaggio
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.
Figure 4.1: Stelpro SWT2F Thermostat Dimensions.
4.3 Cablaggio
WARNING: Risk of electric shock. Installation must be performed by a qualified electrician.
- Assicurarsi che l'interruttore principale sia spento.
- 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.
- Ripristinare l'alimentazione al quadro elettrico principale.
5. Funzionamento
5.1 Impostazione della temperatura
The Stelpro SWT2F thermostat features a simple rotary dial for temperature adjustment:
- Regolazione: 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.
- Posizione 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.
- Fluttuazione di 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. Manutenzione
The Stelpro SWT2F thermostat requires minimal maintenance:
- Pulizia: Pulire periodicamente l'esterno del termostato con un panno morbido e asciutto.amp panno. Non usare detergenti abrasivi o solventi.
- Nessuna parte riparabile dall'utente: The thermostat contains no user-serviceable parts. Do not attempt to open or repair the unit.
- Flusso d'aria pulito: Ensure that the thermostat's vents (if any) are not obstructed by dust or objects, as this can affect temperature sensing accuracy.
7. Risoluzione Dei Problemi
Per i problemi più comuni e le possibili soluzioni, fare riferimento alla tabella seguente:
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Il riscaldamento non si accende. | 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). |
| Il riscaldamento non si spegne. | Thermostat set too high. Thermostat malfunction. | Turn dial to a lower temperature or 'OFF'. If problem persists, consult electrician or replace thermostat. |
| Lettura della temperatura imprecisa. | 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. |
