  • Channel 0 = Physical device used for configuration of e.g. parameters etc.
  • Channel 1 = The thermostat
  • Channel 2 = Internal room temperature sensor
  • Channel 3 = External room temperature sensor
  • Channel 4 = Floor sensor

The following channels should be used with Futurehome:

  • Channel 0 - This channel is not in use. Place it to "no room".
  • Channel 1 - Give it a name and place it in a room.
  • Channel 2 - place this in the same room as channel 1 if you're using internal room temperature sensor
  • Channel 3 -place this in the same room as channel 1 if you're using external room temperature sensor
  • Channel 4 -place this in the same room as channel 1 if you're using floor sensor

Tips: The channels not in use should be placed in "no room", and select type "nothing".

  1. Open the Futurehome-app, verify you are on the right household.
  2. Start exclusion on Futurehome app.
  3. Repeat the same procedure as when including.
