This is one of the greatest products ever! I wanted to add zoning to our upstairs unit so that we could have separate control for our master suite, home office and guest room because the temperatures were so different and with only the one thermostat, the office would end up way too warm in the summer and we'd have to set the master to freezing cold to get anything close to comfortable in the office. Sure, I could have spent time pulling wires, but with this, why? All our other thermostats are focusPros and I really like the simplicity of them. Yes, I used to be all into the fancy touchscreens and such, but since we bought this new house I've decided I prefer the more minimalist interface of these; simple buttons for up, down, and mode settings, clear display, etc. We don't use any of the programming and just set the temp we want and pretty much leave it there. Don't get me wrong, this is a powerful thermostat and can control even the most advanced systems (up to 3H, 2C plus heat pump and aux I believe) and it works with the remote comfort control as well. It took me literally minutes to install; just mount the thermostat where you want it, install the EIM (which is the receiver) near the equipment, sync and done! I used this for our second zone, so I just wired the EIM to the zone panel and it wires just as if you were hard-wiring a thermostat directly. Connections are clearly marked and easy to do. Everything works flawlessly and temperature control is very accurate. Installed the thermostat in our office since it's the room we use the most and added the remote comfort control, which is in the guest room, so when we have guests staying with us they can control the temp of that room from there by selecting 'Sense temp from: This Device'. Once they do it takes control and the thermostat will display 'Remote has control' and show the set temp and current room temp on the display. The whole system is awesome! You can also use this to easily re-locate an existing thermostat. However, after reading many reviews of this product I noticed many people saying that the EIM (receiver unit) goes where the old thermostat was, which while technically possible, is not how it's intended to be installed. The EIM goes near the equipment itself; you just disconnect the existing thermostat wire at the equipment and run a new (fairly short) wire from the EIM to the equipment. You then place the new thermostat where ever you want and you can tuck the old wiring into the wall and cover the hole however you like. Honeywell really created a great product here with this kit and we couldn't be happier. All our rooms are now comfortable because each thermostat reacts to the environment of each room separately.

I purchased this model because the existing thermostat in our home is in a location that seldom reflects the temperature and the rest of the home was either too hot or too cold no matter how we tried to balance the.vents. The kit has three parts - a large (ugly) control unit, the thermostat proper and a return air sensor box. The control unit and the return air sensor are designed to be mounted next to your furnace, which is why the ugly factor probably doesn't matter much. I had to get a spool of 5 wire thermostat cable to properly connect this unit - I have a simple single state heat/cool conventional forced air system. At least a 7 wire wire is needed for two stage and/or heat pump systems. I completed the install myself even though every single DYI site emphasized in very direct language "contact your service professional" which in my case meant a $250 to $500 visit, plus the cost of the unit. If you're remotely adept at wiring simple projects and can read, the install manual is very clear with excellent diagrams for several standard configurations including multi-stage and heat pump configs, and you just need to connect the wires to the right color based on the existing thermostat hookup. If wiring is not your thing, call your HVAC service company. Mine didn't have a common wire that provides power to the control unit (my old thermostat just used batteries). I needed to add that, so before purchasing this unit, make sure your furnace has such a terminal output. I was able to google the manual for my 14 year old furnace and get the wiring diagram for it - I also took the panels apart on my unit to verify it matched what the manual said. The terminals on the furnace were clearly labeled although I verified with a volt meter before doing anything. The other thing you want to do during the install is trip the breaker going to your furnace while you do the connection, even if the furnace has a safety switch when the panels are removed. All in all, the install took about 15 minutes from start to finish, and the unit works great. The thermostat unit is a bit heavy and large - but it works from every room in my two story home. Uses a couple of AA batteries and the manual was also well written. The return air unit is optional, but it's used if the thermostat looses connection to the main unit for any reason, and keeps the furnace/cooling operating based on presets. It involves two wires and drilling a hole in the return air vent going back to your furnace. I haven't installed it yet, but will shortly because I think it's a good safety feature. Because the wireless is not internet enabled (looks like a proprietary protocol used by Honeywell called redlink), chances of the furnace controls being hacked are reduced as the unit needs to "sync" with the control unit by pushing a button on the control unit to put it in listen mode, and then pressing a corresponding button in the setup menu of the thermostat. An internet gateway can be added to the system if you really feel the need to see your furnace controls via the web, but I think personally it's just too much of a risk and cost for what you get. Do I really need to see the temp on my phone? I suppose it can be useful in some cases, I just didn't see the point for me. There's also an external sensor you can add to this unit - the manual doesn't really explain the benefit of that - I can't tell if the external sensor allows the thermostat unit to respond differently and learn how your furnace and your house responds to heat/cool cycles. Some high end furnaces do that, not sure if this unit would do that or not. My setup is so conventional that these extras seem like bling more than function.

This thing finally solved a problem. On the second floor of my house the thermostat is in a bedroom that gets sun all morning and is in the shade all afternoon - so every other room on the floor is either too hot or too cold depending on the time of day. Moving it through the wall behind just puts it in a different bedroom (same problem), moving the line out to the hallway would involve drilling through many studs and maneuvering around doors. Whatever genius installed the system never bothered to connect the C line through from the basement two floors down and across the house, so using a smart thermostat would require a lot of wiring and effort. With the Honeywell, the base unit sits in the basement attached to the boiler control unit (R, W, C) while the thermostat can be placed anywhere in the house. Having it sit in the hallway between all of the bedrooms seems to work perfectly well. Setup took maybe 20 minutes and instantly all three rooms are at a more moderate temperature.

Perfect solution to comfort issue. The master bedroom was always hotter than rest of upstairs—farthest room from HVAC—plus it has a huge skylight. Older house and vents are round—preventing use of temp control via register; flat roof and no attic so any ductwork change would involve taking down ceilings. Now room is much more comfortable—turns out four degree difference between old thermostat location (hall) and new thermostat (MBR). I had our HVAC company install ($280).

Great product kit. The return air sensor is NOT as pictured on box or inside the installation. There is a discharge/return air sensor in the package, just a different one. [see product image that was added] In talking to Honeywell Tech support about the change in the sensor, to see if it was a packing error at the plant; they confirmed the part received is the correct one. It became clear during that call that Honeywell will NOT honor a warranty on this line of products unless PROFESSIONALLY INSTALLED to specifications. You might have to prove the install; depending on the situation. Check the Honeywell website for products that are DIY and those requiring professional install, as Honeywell has both. This is a great [expandable] system and worth the extra money of having it installed by an HVAC pro. The A/C company doing my regular service indicated there is no way they could meet the Amazon.com price...AND they usually do NOT install customer's goods. Since an active customer, they agreed to do it in this case. Strongly suggest checking this out in your area first...

Great product and it solved my problem of the original thermostat being placed on a cold outside wall. This was easier than relocating the original thermostat. This could not be any easier to install. Before you do anything, read the instructions. My system was a simple conventional 1 heat, 1 cool , 1 fan so was an easy hook up. Turn your system off and note the colors of the wires going to the various terminals marked C (Common), R (24 VAC), W (Heat), Y (Cool/Compressor), G (Fan). If you have more wires, your system probably has more stages or Aux heat. I could have located the big receiver right where the old thermostat was, but as others have noted it is quite large, gray and kind of industrial looking. Don't know why Honeywell didn't choose some off white beige. I chose to install it close to my AC system and simply cut the thermostat cable (usually brown) so I had enough to mount it on the wall. Strip back the same color wires noted, push them into the correct terminals and you're just about done. The instructions for wall mounting both the receiver and wireless thermostat are lacking, but it's fairly straight forward once you figure out how to pop the covers off. Once you install the batteries into the thermostat, connecting (pairing) to the receiver is very straight forward. Programming the thermostat is easy if you desire. I chose to just leave it in HOLD mode for now while making sure it behaves properly. As others have noted don't even think of contacting Honeywell if you need tech support are a mere end-user. They make good products but I have had them hang up on me when trying to get tech support on another product when the found out I wasn't an installer. Works great now and the temperature the thermostat reads is the actual room temperature.

Excellent easy to install

This works perfectly for us and our home. We have propane and we also have a huge great room with cathedral ceiling. It takes a lot to heat it. We use our fireplace with a blower as well as a pellet stove in another room. However, when we go to bed and just want heat in our bedroom, with this thermostat kept in our bedroom, we are able to turn it on about 8pm and have just the bedroom heated and not have to waste propane all night to heat the rest of the house.

La pareille super il ne fonctionne pas si vous avez un biénergie.. Regardez plutôt pour le prestige..Mais la machine wow pas de négatif..Merci à vous et Amazon…

It works okay, but there is a LOT of profit built into the price of this item and a lot of price saving shortcuts. It's a very basic programmable thermostat ($30) split into two pieces, re-connected by the guts of a wireless light switch (also $30), yet somehow ends up being $400. Cheaper versions (from different manufacturers) appear to be junk, so I bought this. Despite the inflated price, there are some cut corners: - the duct sensor is a hardwired probe a few inches long, to be installed in a hole drilled in the return air duct. Its purpose is to prevent extreme temperatures if the wireless unit disconnects. However there's no way to tell if it's working, other than disconnecting your thermostat and waiting for the house to cool below 15 degrees. A couple of LED indicators or even a numeric indicator would be welcome. - the simplest install would be to put the base where the old thermostat was, connecting to existing wiring, but that duct sensor is way too big unless you want a meat thermometer looking thing protruding into your living room. They could have included a plain thermocouple (a $5 part) for install under the plastic housing of the base unit, or documented the type of thermocouple (a $0 effort) for the end user to purchase one himself. - the quick connect terminals on the base look and feel like the cheapest flimsiest thing in the world. Better spring terminals, or even simple screw-down terminals, would be preferable. When you install, secure the incoming wire near the base unit (with a cable tie or similar), to relieve strain on these very inexpensive terminals.
