Thermostat makes clicking noises very frequently (short cycling)

Safety: Software changes can be made with power on. Turn off power only if relocating the thermostat.

Steps to reduce short cycling:

• 1. Adjust cycle settings: In the thermostat menu, reduce the cycle rate or increase the minimum on/off time if these options are available.
• 2. Improve location: Move the thermostat away from drafts (doors, windows, vents) and away from direct heater airflow.
• 3. Check heater sizing: An oversized Stelpro heater can cause rapid temperature swings. Consider using multiple smaller heaters or adjusting wattage.
• 4. Verify sensor stability: Watch the displayed room temperature; if it jumps rapidly by more than 0.5°C, the sensor may be faulty. In that case, replace the thermostat.
• 5. Enable adaptive control: Use any available adaptive or PID control modes to smooth cycling.

Note: Some clicking is normal, but very frequent cycling can reduce heater life and comfort.
