Possible Causes
Incorrect cycle rate setting, Thermostat mounted near a draft or on an external wall, Radiators with no thermostatic valves, Boiler anti-cycling time misconfigured
How to Fix / Troubleshooting
Safety: No high-voltage work required.
- Step 1 – Relocate if needed: If the thermostat is on an external wall or near a door/window, consider relocating it to a more representative room location.
- Step 2 – Adjust cycle rate: In advanced settings, set the cycle rate appropriate for your system (e.g., fewer cycles per hour for radiators, more for underfloor heating).
- Step 3 – Enable optimization: Activate adaptive or optimization features if available to smooth temperature control.
- Step 4 – Balance system: Have a technician balance radiators and check boiler anti-cycling parameters.
