To edit this setting via WiFi you must use a computer. This cannot be done from a mobile device, the MyHeating application or the physical device itself if you are connected to WiFi.
To start, visit https://my.warmup.com/login and logging into your My Heating account. Select the human outline icon at the top of the page to display your “Personal Details”. Scroll to “My Locations” and select the gear by the location that you’d like to edit. Scroll to the bottom of the page that you are directed to and select “Edit Room”. This will bring you to a page with “Edit Location” at the top. Below this you will see a drop down for temperature format. Select your desired format from the menu and then select “update location”.
Please allow 2 minutes for your 4iE to reflect this change.
