Thanks to everyone for their response, I am being told by my contractor that he believes that it will be a Carrier brand system, however, he is getting back to me on make and model and if it is a heat pump. In the mean time, is there an ISY controller I can buy to start learning how to program…etc

That I don't know, I will have separate system on each floor, 2 thermostats, that I know….assuming I have a heat pump, what thermostats and systems should I start looking at until I find out?

I maybe in error….I do not know the system they are putting in, I just assumed since it was a new system it would be a 5 wire….but there is no natural gas where I am, so it is an electric heat system, that I do know, some folks said it they use zwave to accomplish this, so I don't know at this point. thank u

Ok. thanks, I will research that. Might be a week or two before I get….thx again

Thank you, The HVAC unit is new, not installed yet (new house being built) so I have my options open, I really would like to go with something reliable and easy. I wouldn't mind using the Insteon thermostat, but the others seemed to look nicer and have more features (not that I need them). I do not have thermostats yet. I just want to shut the A/C down when people leave windows and doors open. I would prefer one thermostat that controls both heating and cooling. Also I would like to access the ISY remotely. The property is a vacation rental and I live out of state from it. Thank you again.

Hi, I am about to purchase the ISY-994i, what I am trying to accomplish is shutting off the AC, no heat pump, just typical residential AC and electric heat, (new installed system, 5 wire etc) system when the windows or doors are opened. Can someone recommend which version of the ISY I need and two compatible thermostats other than the insteon version? I am familiar with the door sensor I need. Thank you!
