Channels

Heatit Z-TRM3 has support for the Multichannel Command Class, meaning when included to Futurehome you will get multiple channels. These are the channels:

  • 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"

 

Delete/Exclude

Some times you want to remove a included device, or delete it to add it again. To exclude the thermostat from your Smarthub do the following:

  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.
  4. The thermostat will display EcL if the device was deleted.Multireg_mockup_EcL_NO.png
