Kentinada Posted June 4, 2014 Posted June 4, 2014 I have an ISY994 running V.4.0.5 software. My house currently has 4 heating/AC zones each with its own programmable thermostat. I am considering replacing them with INSTEON thermostats so I can control them remotely through my iPhone. Do I just need to buy 4 INSTEON 2441TH thermostats? Any guidance would be appreciated. Thanks.
MaddBomber83 Posted June 4, 2014 Posted June 4, 2014 It sounds like you already have a zone controller acting as the middleman between the hardware and the 4 separate thermostat logic. If this is the case (as in your thermostats themselves are nothing special) then the Insteon TSTats should be a plug in solution for you. I would recommend picking one up and making sure it does what you expect first before dropping the cash on the other 3. I have a halfway functional (still installing / programming things) zone control system where the ISY is the brains behind the system. This is just to say that if for whatever reason there is some incompatibility it is likely something that can be fixed in this thread.
