You may disable the Cosy and revert to your original heating controls (e.g twist dial thermostat) by following the steps below:
- Press the OVERRIDE button (in the middle) on the Cosy switch so that the Cosy goes OFF
- Turn your original twist dial thermostat to your preferred temperature
- Set the boiler timer to your original heating times for 'on' and 'off' e.g On all day, On Twice
- Once you have confirmed your original heating controls are operating the heating correctly you can unplug your Cosy
