Demo mode

Demo mode
You can now interact with Cosy as though it’s live but you can’t control the heat just yet.
Things you can do before the switch is installed
•Set your temperature settings for each of the lifestyle modes (settings > temperatures). Select
the mode and rotate the dial to the right temperature. On iOS devices you need to tap the dial
rst to set the temperature and again to save it.
•Look at the default proles (settings > schedules > proles > weekday). Try altering and
changing events, look at the weekday prole or add your own prole.
•Select the prole you wish for each day of the week (settings > schedules).
•If you need to, add additional users. They’ll need to download the app and follow the
instructions.
•Take the Cosy display to where you would like to use it most often and see what temperature
it reads.
•Do not position the Cosy display near a heat source (such as a radiator or a light) and avoid
direct sunlight.

Installing the Heating switch

9
Installing the Heating switch
The switch is a mains powered thermostat switch. It works in addition to your existing thermostat -
which can stay where it is - so no redecorating required!
The switch can control the heating for up to 2 zones, however you will need to purchase an
additional Cosy Display for each additional zone.
The switch requires a competent electrician to install it and takes 15-45 minutes to install and test.
If you have bought Cosy with installation an installer will contact you and arrange a time and date to
come and install your switch, test the system and make sure you are entirely happy with your Cosy.
If you have bought Cosy without installation you will need to arrange an installation yourself.
Go to www.comehometocosy.com/support where you will be able to download the Heating Switch
Installation Instructions.
When the installer/electrician arrives give them the Cosy Heating switch installation instructions, the
Cosy switch box and show them your heating system.
Once the electrician has installed the switch/es they should test the system to check that your
heating is up and running.
For the system to work properly you need to check three things:
•The switch/es are active (the centre button is green when switched on)
•Your previous thermostat is set to maximum (if you have one)
•Your heating is set to always on
