A:AnswerI just looked up your model and it looks like the ones I replaced. My two older Honeywell thermostats were swapped out with the two home smart color thermostats. The wiring on most thermostats is generally the same depending on your system and it capability. There are a couple of limitations about some systems that these will not work on. One that I can think of right now it electric baseboard heat (these will not work with that type of system). You can check on the Honeywell web site for more details and their customer service is very good. They answered my pre-purchase questions in a very timely manner. There are about six different combinations of wiring that you can use with these thermostats. You do need a "C" wire and that can be hooked up in about five minutes usually, my older thermostats didn't have that wire attached. There should be extra wires in the bundle behind the current thermostat and you just need one to be hooked up on you main units control board and you're good to go. I did exactly that and things work very well. Just head the warnings of turning off the units at the breaker before doing the wiring. The new thermostats are awesome, hooked them to the app and the Alexa!! Just be aware there are some limitations in the Alexa skill from Honeywell but you can change the temp, get the temp and a couple of other things, which is all you really need! That's what you would do if you walked over to it and changed it there once it was set up.Good Luck!

A:AnswerIf what your asking is if the smart thermostat would activate your secondary heat source like electric, or gas when the outside temperature goes below the threshold the heat pump's sensor are set to, then answer is yes so long as you have the smart thermostat connected to wifi. The smart thermostat would not utilize the extra two wires connected to your existing thermostat and instead utilize weather information for your location on the internet to activate your auxiliary heat source.
A:AnswerHi Shaw, if the thermostat loses power, you will receive an alert indicating the thermostat is not able to communicate with our servers. Hope this helps. Have a great day!
A:AnswerYes, the unit can be used without a "C" wire. You do lose the ability to run the fan in your furnace, independently from the furnace.
I believe that you can also have multiple zones, but I have not done this myself.
Good luck

A:AnswerThat is what it should do. When you turn your humidistat to the on setting then the thermostat controls everything. When you set your humidifier stat at a percentage of humidity then the humidistat cuts the power off to the thermostat and it takes control and decides when to turn the AC on or off in this case at 60% humidity.
A:AnswerThere is nothing about this thermostat that is different from any other programmable thermostat that would address any of these questions. What is unique is that it becomes a node on your WiFi ethernet and it gets its electric power from your furnace rather than from a battery. As a result you can set up an internet account in Honeywell Home and by logging into it from your smart phone or computer monitor and change temperature.
A:AnswerYour thermostat would need to have an AUTO setting
If it only has a Cool/hear/off mode it would not do what you are looking for.
In heat mode it will keep the temp at or above the temp you set it to but not the maximum temp
In cool mode it will keep the temp at it below the temp setting you set but not above the minimum temp
If your thermostat does not have an auto mode there are other wifi thermostats you can look at that do have an auto mode setting
A:AnswerHi BT! The Resideo Honeywell Home Smart Color Thermostat is compatible with common 24 volt systems such as forced air, hydronic, heat pump, oil, gas, and electric. It will not work with millivolt systems, such as a gas fireplace, or with 120/240 volt systems such as baseboard electric heat. Additionally, it is compatible with 3 Heat/2 Cool Heat Pump and 2 Heat/2 Cool Conventional systems. If you have any other questions regarding compatibility, or need help setting the thermostat up with your system, don't hesitate to reach out. You can give us a call at 1-855-733-5465 and our agents will be happy to help!
