Manual temperature can be used for when the heating schedule is not needed in an individual room or the Living Zone.
Manual temperature is particular useful if you have a guest room that is rarely used. The heating schedule could be active when the guest is staying in the room and when the guest leaves you could switch to a lower manual temperature saving you energy.
Please note that any room can be changed into an Individual room by following the instructions in this article: What is Living Zone?
Manual temperature for an individual room can be activated as described here:
1. Access the right side panel of the Danfoss Link App.
2. Scroll down to the "Individual rooms" section.
Click on the room name of interest.
3. Slide "Manual temperature" from "Off" to "On"
4. "Manual temperature" is now activated.
Choose a different manual temperature if needed.
