If the Power LED on your WATTS 294EXP Smart Boiler Expansion control unit is off, you can troubleshoot the issue using the following steps:
1. **Check Supply Voltagអ៊ី៖ **
- 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 the correct range and the Power LED remains off, the control unit may be faulty.
2. **Communication Check:**
- Ensure that the boiler expansion wiring terminals 1, 2, and 3 are connected using a 3-conductor 18 AWG LVT wire if the connections are less than 100 feet (30 m).
- For connections exceeding 100 feet (30 m) or installed in high radio-frequency environments, use a 3-conductor 22 AWG shielded-twisted pair.
- Verify that the wire color codes are correctly placed in the terminal locations as the boiler expansion wiring is polarity sensitive.
By following these troubleshooting steps, you can identify and potentially resolve the issue with the Power LED being off on your WATTS 294EXP Smart Boiler Expansion control unit.
