If the Power LED on your WATTS 294EXP Smart Boiler Expansion control is not lit, follow these troubleshooting steps as outlined in the user manual:
1. **Check Supply Voltage**: Use an electrical meter to check that the supply voltage is between 103.5 and 126.5 V (ac). If the supply voltage is within this range and the Power LED remains off, the control may be faulty.
2. **Verify Wiring Connections**: Ensure that the boiler expansion wiring terminals 1, 2, and 3 are connected using 3-conductor 18 AWG LVT wire if the connections are less than 100 feet (30 m). If the connections exceed 100 feet (30 m) or are installed in high radio-frequency environments, use 3-conductor 22 AWG shielded-twisted pair wire. The wiring is polarity sensitive, so double-check that the wire color codes are correctly connected to the terminal locations.
By following these steps, you can troubleshoot the issue with the Power LED on your WATTS 294EXP Smart Boiler Expansion control ប្រកបដោយប្រសិទ្ធភាព។
