The WIKI page covering Thermostats ( https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:Linking_a_Thermostat )

 

States there should be 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

 

I have deleted and relinked my device a few times and I only ever get 3 nodes

 

Main, cool, and heat.

 

Is this expected and the WIKI needs to be updated?  How do I check the current status of the fan on the furnace?

The Smarthome manual

http://cache-m2.smarthome.com/manuals/2732-xx2-en.pdf

 

Has the following:

 

Group 1-Cooling mode change (scene control)

Group 2-Heating mode change (scene control)

Group 3-Dehumidifiation, high humidity setpoint (scene control)

Group 4-Humidification, low humidity setpoint (scene control)

Group EF - Broadcast on any change (notification group for linked software controllers)

 

I don't think groups match up with Nodes in ISY, but it is interesting, and would be curious to know how things match up.

 

Thanks

Fan is found under the main node.

Ok so a 'node' doesn't always mean an entry in the ISY like the Main, Head Ctl and Cool Ctl?

All my 2441 thermostats (3 wired, 4 wireless) show only three nodes, main, heat and cool. But, I can trigger a program based on the state of the fan and/or use a program to control the state of the fan.
