I have single zone climate, without automatic control. Will this unit work?

I have a single zone also. My a/c is not automatic at all, works just fine. I read some peoples it didnt work,but i have no complaints.

I have the same manual single zone setup and it will work just fine. Just remember to plug in the second harness for the display lights. The buttons will only light up when you turn on your vanity or headlights.

YES. This Thermostat will automatically switch your system from cool to heat or heat to cool depending on the temperature in your home. It is also capable of controlling a "heat pump" system (a system where the compressor unit outside your home is run to produce both cooling/air-conditioning and heating).

I used mine to interface to a zone controller so that would not be available as an option. I did not see any options on the programming of the stat. to control speed any way. My best guess from not seeing that option is that the thermostat would not control the speed but cant say for sure, I am not sure if your air handler has any sensors in it to detect if it needs to change fan speeds without a signal to do so from the thermostat, you could check on what actually controls the speed of the fan your equipment. This thermostat has tons of programming options and is the very best I have ever had or seen, but again I did not see programming options for speed control.

NO -- not automatically anyway -- I would recommend a timer switch, that you can turn on for 10 to 30 minutes. If the dehumidistat switch is already installed you could add the timer switch in addition to it...

I have found that the unit will automatically restart, but it will not save your settings. You will need to re-program F/C and the temperature after a power interruption. I have been pretty happy with our unit thus far. -DA

There is a vacation mode you can trigger by wiring a pair of wires to the thermostat and using a contact switch which can presumably be controlled by the multi-zone system. I ran the wires to control mine but I haven't hooked it up to anything yet.

John: No. This kit is designed for a single zone (multi stage system--this description often confuses people. multi-stage refers to differing heat and or HVAC levels---not number of zones in the house). The included interface panel is installed at the equipment and serves one zone only. If you have a home with 3 zones and 3 separate HVAC units, then you would need 3 kits (be careful here because the wireless signal of each unit might bleed over and cause problems with the others). If however you have a home with one HVAC unit running 3 separate zones (which is rare in a residential set-up) then you need to change out your existing Zone controller at the equipment and go to the Honeywell Truezone Panel. Honeywell does make a wireless adaptable Truezone System (not sold on Amazon). For a one plant multi-zone system you would need the Truezone panel, wireless Multizone interface and the required number of wireless thermostats. No sure Amazon sells all you need. I would strongly recommend a simple call to Honeywell Customer/Tech support and lay out what you are trying to accomplish. Be careful how you ask the question. The Honeywell unit Amazon sells is designated (by model number) as one that should only be installed by a professional HVAC tech (of which I am not). When I called about my unit, they would not answer once I told them I was not a HVAC contractor. I got around it by calling again a fibbing a little. Alternatively, you could try searching the model number and calling one of the vendors (ie SupplyHouse) as they offer free technical advice--but not as good a price as Amazon. Lastly, unless I had much experience with HVAC systems, I would not attempt installing this unit in a multi-zone system with professional HVAC help. Good Luck, Steve

I am not sure but would suggest just calling Honeywell and run that by them. I do not think it would, but I have one of each of these in two different homes and it is great. I would highly recommend but not sure about multiple zone question. It is very user friendly one set up.

It's not cheap, but I upgraded from this thermostat to a Honeywell YTHX9321R5061 Prestige 2.0. It works with my heat pump. It has an outdoor wireless temperature sensor. It has a wireless remote with remote temperature sensing, too. With an additional module, you can control it via the internet. If you can afford the unit, you'll love the way it works.

You need to have one of the multi-zone controllers and receivers attached for it to work correctly. If the HVAC systems are in different locations, then you need separate controllers that have the builtin receiver. I have the 3-zone unit (only using 2 zones currently) and it works great! All thermostats must be on a separate channel and "associated" with a separate zone. They cannot be on the same zone. These run on Honeywells proprietary Redlink protocol and are not compatible with other wireless protocols. It is a very solid system though... I did a lot of research before I took the leap. It's Pro stuff. Hope this helps. You need to have one of the multi-zone controllers and receivers attached for it to work correctly.

Yes. From the manual 37 69-2814EFS-03, Auto changeover: This feature is used in climates where both air conditioning and heating are used on the same day. When the system is set to Automatic, the thermostat automatically selects heating or cooling depending on the indoor temperature. Heat and cool settings must be at least 3 degrees apart. The thermostat will automatically adjust settings to maintain this 3-degree separation. Note: Select Auto Changeover on the Heating and Cooling System Changeoverscreen under Advanced Preferences. See "Setting advanced preferences" on page 38. Yes.

no. there is a key pad on the front of the unit so you can select the temperature that you would like. Its worked great for us so far. Good luck

If the existing thermostat just closes a low voltage circuit it should work. That's most two wire thermostats. The only other considerations are the minimum run time and the low & high set point. You can adjust the temp spread on this unit using jumpers inside it.

You will not have that problem with this thermostat. Mine works like a charm, and I like the fact it is digital...and accurate.

I would say No...it has a "thermostat" dial, and in our large garage it keeps it at 45 degrees at the lowest setting during the winter. The first on e I bought would not cycle on and off , so make sure its working like it should.
