Possible Causes
Oversized boiler, Incorrect differential or setpoint, Poor system water volume, Faulty thermostat placement
How to Fix / Troubleshooting
Safety first: Turn off power before adjusting internal controls.
- Check thermostat location: Ensure thermostats are not near heat sources or drafts that cause rapid temperature swings.
- Review control settings: On Utica controls with adjustable differential or outdoor reset, widen the differential or adjust the curve to reduce cycling (follow the installation manual).
- Increase system volume: In systems with very small water content (e.g., panel radiators), adding a buffer tank can reduce cycling; consult a heating professional.
- Monitor operation: After adjustments, observe run times and room comfort.
