Default temperatures


Your Cosy smart heating control has four modes. By default their ideal temperatures are:

  • Hibernate: 6°C
  • Slumber: 12°C
  • Comfy: 18°C
  • Cosy: 22°C

These are the temperatures that your system will try to achieve whilst in each of the modes. 

Changing the ideal temperatures


You can change the ideal temperatures for Cosy, Comfy and Slumber from the Cosy app (Hibernate is always set to 6°C). We recommend adjusting them to suit your home.

Provided you are using the latest version of the Cosy mobile app, you are now able to adjust the ideal temperatures in 0.5 degree increments.
