Linking a Thermostat V1

Linking a Thermostat is the same as for most other Insteon devices.

See Link Management Menu

Linking a Thermostat V2

ISY firmware version 2.7.9

  • If you have already installed a thermostat adapter in an earlier firmware version it must be removed from ISY
  1. Ensure the thermostat is in the OFF mode before linking to the ISY
  2. Use Link Management | Start Linking
  3. Press and hold the Set button on the thermostat for 3-5 seconds
  • You can safely remove your thermostat queries
  • Changing the Fan status (on the thermostat itself) too quickly causes the updates not be sent to ISY. This is NOT a bug but limitations on the thermostat adapter interface.

The thermostats are represented by 4 nodes

  • The main node - this is the main thermostat node
  • Cool Control - indicates when the thermostat is calling for Cool
  • Heat Control- indicates when the thermostat is calling for Heat
  • Fan Control - indicates when the fan is on/off

The main node can be used as a responder in any scenes and thus you can impact changes to the thermostat settings based on other INSTEON devices/ISY scene.

The other nodes can be used as controllers in any of your scenes. So, for instance, adding the Cool Control in a scene as controller would cause all responders in the scene to turn on when the thermostat is calling for Cool and turn off when the thermostat is calling for Heat.

Thermostat FAQs

If you are having trouble linking a Thermostat please check the following:

  1. Signal related … too far away from the closest Access Point
  2. Defective dongle
  3. Wrong address

The version 1 Insteon thermostat does not automatically inform the ISY of it's current status. For the ISY to have a reasonable idea of the thermostat's current temp, setpoint, mode, etc. it will need to be polled periodically.
