I have 2 HVAC units. Do I understand this correctly that one of these units comes with everything to control both systems

Kurt, I am pretty sure that the answer to your question is no. You can control more than one thermostat from one IPhone or PC, but each HVAC unit will require its own thermostat.

I believe so but since I only have 1 HVAC, I suggest you research manufacturer specs to make sure. Just note that, as mentioned in my review, this product drops from WIFI so it is NOT as dependable as I wanted it to be. I find myself having to reset this often because whenever I want to control remotely, it is "disconnected"...which defeats the purpose of having it. You mileage may vary. I did try 4 different WIFI access points just to rule out incompatibility issues.

I believe that the two units must share a common ground, Most homes are wired this way. Our units worked well from one end of our house to the other.

There is a second part that they sell to go with this. It is a thermostatic temperature control. About $18. They should clarify that most people would need both pieces. It has the two inputs and connects directly to the unit. Then you can set a temperature that you want. This setup works very well.

Yes you do have to purchase other parts but it all depends on the type of furnace you have and where you plan to install it. It is better to consult a HVAC professional to determine the parts you will need or check out u-tube videos to see what they suggest.

you can control the heat for both sides at the same time, or you have the option to turn only one heater on at a time. so i assume they mean u can control both heaters because you can turn one off. you can't control both separately if both are running.

I did it myself, with basic knowledge of wiring. You might have to do a bit of research depending on your units wiring, but it really isn't any harder than any other thermostat.

You do not need to purchase two. If your system only has one sensor that's all you need. In my case, the water sensor failed and this item replaced it perfectly. My system's original air sensor is still working fine and I expect it will for a long time as it is sheltered from the elements.

It comes with everything you see; the outdoor sensor, the remote sensor, the IAQ module, the two furnace sensors, and the thermostat. Everything you need!

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'm not an expert, but I think you'll be good with that. There are a number of ports for wires that control different functions (heat, air conditioning, fan, power, etc.)When I installed mine, I had the opposite issue. Only two wires from my prior thermostat (simple heat, no fan). I needed to get an extra power source kit with a wire just to power the Venstar. Hope this helps.You could also go to the Venstar site and download the installation instructions prior to buying it just to see if your colored wires match their diagrams.

yes this unit works fine it works just like a thermostat - i have 3 blue flames @ my residence - currently i am in the process of removing my heating system as the blue flames are very efficient and operate wether the power is on or off - also i will have a fourth installed by october

Hello, When I purchased this it came as 1 unit so if you need 2 you will have to order 2. hope this helps.

Hi, it comes with an owners manual...which wasn't very helpful. I ended up calling an hvac tech to install and he convinced me to install an aprilair controller. I returned the Honeywell. My system was too complicated to figure out on my own and I'm fairly handy. The wiring wasn't as straight forward as I thought it would be.

For me there was one already installed to control a fan. The existing one went bad and locked into full power so I replaced it. There was three wires from my fireplace. One is power that is looped with a thermostat and the other is a neutral. Should be simple swap out, resolder the wires and it's ready to go.

The Ecobee thermostat is a two piece unit: the control unit that you put in your hallway and the equipment interface module which you put in your cellar near the furnace. When you buy the thermostat, you get both pieces and you need to use them both. They connect by the cable that your original thermostat used to connect to your furnace and AC, so you don't need to run a new cable. You then connect your furnace and AC to the equipment interface module. Piece of cake, right? WRONG! This is a very flexible and complex unit, and can handle all sort of fancy systems, so you really need to know what you're doing to connect it. I have a separate furnace, AC compressor, and air handler (and a degree in electronics), and it took me about 5 hours with the furnace and air-handler schematics to figure out how to connect this thing. It turned out the original contractors who installed the AC and furnace wiring made mistakes; my old thermostat forgave them but the Ecobee wouldn't. That said...I love this unit. It was worth the time and expense.

No. Each one runs on a separate controller. I would assume the company makes a add on to control both.
