A:AnswerYes I have a house with three zones on the one Hvac set up. The blend in perfectly and allow remote setting and adjusting with the internet. The app is great too
A:AnswerIt appears to operate in sequence with both heat pump systems. I only have one heat pump but I can think of no reason why both cannot be calibrated to the same settings.
A:AnswerYes, You can set up a schedule for every day during the week. They have the option to set the temperature when you wake up, when you leave, when you come home, and when you go to bed. I believe you can also add more on top of that.
A:AnswerYes, you can cover the ends of the outdoor temperature sensor and leave them unconnected if you install the WiFi Smart Color Thermostat, which displays an outdoor temperature based on weather data from the internet. I don't think you'll find the WiFi Smart Color Thermostat to be much of an upgrade from the TH8320U unless you really want the ability to control your thermostat from a smart phone.
A:AnswerProbably not. It is looking for 24V AC. You could ask at the Honeywell website, they should be able to give you a definite answer. But if you are wanting to use the Alexa or Google to control it, you will need to have a WIFI network available. So you will have to figure that part out. If you don't plan to use Alexa or Google, then you could find a much cheaper solution then this thermostat. Good Luck.
