Theromstat/HVAC system control with Elk M1/Insteon

[skyphyr]

Hi all,
 
I'm in the middle of replacing my ADT alarm system with an Elk M1 and ISY-994i, and I'm currently trying to figure out whether there's a way I can hook my existing thermostat in to these systems. It's a Honeywell of some kind, but I can't see a model number on the front.
 
Any tips on how I start figuring this out and what the options are?
 
Cheers,
 
Alan.

Don't.
 
You would need some sort of communicating T-stat. Other than that, you'd have to provide a basic dry contact at the T-stat and that's really not going to be the smartest way to go in the long run.
