All this process is SOOO Tedious. I checked my thermostat is corrected to my WiFi router, it's there, But I can't register my device using my laptop or phone, and no error message is being displayed after the registration "finishes".

All fun, games and CZcams until you don’t have a board on your furnace

THE WORST terminals I’ve ever had to use. Pure hot trash!

This disables the ability to use a Fan independently. Does the C-Wire Adapter basically do this same thing or does it have something (like a battery) to allow it to run the fan independently?

Hoe do I find the mac address after the installer failed to set up my wifi?

Now how do you get the wires out of the terminals?

i love honeywell wifi thermostats

Thank you. Working!

I don't have a C wire. My furnace's C terminal already has a wire (white) in it though??? I did not, however, find any additional wires in my wall, but the white wire on my old thermostat is in the white terminal. I'm lost..... I thought I would surprise my husband by doing this myself, but I don't think at this point it's going to happen 😳

Did not work.

Muchas gracias bien esplicado el mejor video

Not helpful my hvac system started doing some weird electrical buzz and I disconnected immediately

2:55 Since the smart thermostat's G terminal is no longer connected, this video says that whenever the AC (Y) or Heat (W-O/B) is powered/switched on by the smart thermostat, the fan/blower will automatically come on too... Is it jumpered at the air handler?

3:36 Can I just skip this part -- moving the G-wire at the air handler, from the G terminal to the C terminal ? My multi-meter shows 27V with the R & G wires at the Smart Thermostat (while heat pump & air handler is Not running). So when the G wire is connected to the C (common) terminal at the Smart Thermostat, it should provide constant power to Smart Thermostat. 4:42 The G terminal isn't connected to anything at the Smart Thermostat. PS - my heat pump provides heating and cooling.

The G jumper is ironic, you got to correct this video

THANKS. my have an extra Blue wire. So I used as C wire . Just connect THAT BLUE to both, at Thermostat and at heater control box

I cannot believe this worked!!! Fingers crossed it continues to work.

Good looking !

what model number is this thermostat?

Doesn't a heat pump system ALSO blow hot or cold air out of vents inside your home?? If you have electric only (no gas) AND one big unit that sits atop the roof and does everything AND heat blows warm air and AC blows cool air out indoor vents, then what kind of system is that?

Muchas gracias por ested video el mejor bien explicado vi muchos pero con ested entendí en la primera vez gracias

You should remove the “g” tag off the green wire because it is no longer g but “c” and mark it “c”

where is the Device CRC number? I bought a home with the T5, took thermostat off the wall, but does not have the CRC number, only the Mac ID only on the back of thermostat

Very good

Very helpful, the box though should mention the C-wire on the front of the box in big letters instead of fine print on the back!

How to connect to wifi after my contractor hit”set up later” ?

Why call it a "c" wire? Isn't it really a neutral?

This was very helpful your video was very easy to follow through

This is a question for Honeywell : have you tried to watch the recommended video on wifithermostat.com/installationvideos. ??? Come on... this link is the perfect recipe for huge customer frustrations. we are 2020 and the product is still available so please update this video.

Why do you instruct us to jumper the Y terminal to the G terminal in the furnace. Isn’t the fan operation and speed controlled by the furnace control board when the G override line is not active?

I want to replace a Honeywell Chronotherm III with the Honeywell RTH9585WF thermostat. In the existing thermostat I have, C, R, Y, G & W2 wires. I also have E and O wires, which are connected to the thermostat. . Any idea on what they would correspond to on the RTH thermostat? The system is a Trane heat pump.

Why do I keep getting cant register gateway? My thermostat is connected to my wifi but I cant seem to add device, plz some help

I needed the jumper. No fan with out it.

What if i also dont have a Y wire? Can i short the g with something else?

Don't do this, there is a better way, that keeps all of your 'stats functions. Find that unused blue (or black) wire deeper in the wall by gently pulling out the cable. Clean that wire and insert it into the "C" spot. Go to the furnace/AC. Start with the yellow wire in the cable from the thermostat, which is connected to the red wire in the cable going to the condenser. Since that wire is clearly Y, the other wire in the cable going to the condenser (the white wire, since it's a two-wire cable) must be your C wire, and you can connect the blue wire in the thermostat cable there (after turning the power to the furnace off and stripping the wire end back, of course).

This WiFi thermostat is the biggest fucking headache I've had in a long time. All customer service goes through india or some shit and I couldn't understand what the fuck they were saying. Talked to 3 different people who all told me different things and got me one step further into another blocked wall. Never got the damn thing to work. Easy installation my fucking ass! FUCK HONEYWELL!

Funny (NOT funny) that you instruct the installer to turn the circuit breaker ON after the installation is complete, yet YOU NEVER ADVISED TO SHUT OFF the power!!! Shutting off the breaker should be step #1 for not only preventing frying your control board, but also for SAFETY! So much for thinking the manufacturer (Honeywell) will provide a accurate DIY video! #LAME

By jumpering G and Y, the blower will be ON whenever the compressor is ON, but will the fan blows the same way when the heater is ON?

How do I add a red link outdoor lock out sensor for heat pump with this thermostat

Using the G wire as the C wire is a TERRIBLE idea!! I added a Honeywell RTH6580WF to my home recently. I discovered no c wire. Without knowing what all it involved, I found the blue wire tucked into the wire bundle as it had been cut off since not in use. I stripped it and applied it to my thermostat. Still no power. I then went down to my furnace to see the blue wire was not hooked up either it was just wrapped around the same wire bundle going to the thermostat. I stripped it and hooked it to the C terminal on the furnace. Now the C terminal had a white and brown already attached going to the AC. But you can hook more wires to the C. You can hook the 3 right into the terminal or you can bundle them together with a 4 wire called a pigtail then you only have one single wire hooked to the C terminal. User preference. So don't just assume because you found the blue wire in your wall or wire bundle behind your thermostat that its connected to the C terminal in your furnace. You will be best to take the panel off your furnace , find if a C wire is connected and determine the color while making sure it's the wire bundle going to the thermostat.

might as well just pull new wire...

these units are stupid: they dont allow basic access from a computer or web browser, have no built in http access and require a subscription, a SMARTPHONE, or central server at Honeywell or NEst or who ever makes it and they spy on you. Just buy a direct IP theremostat like this one. www.amazon.com/dp/B07KMQMR9P

If you have a wood stove, you will want that G wire to run the fan only

What if the jumper is between RC and RH?

It can work if cooling or heating but when you need at same time system OFF and only Fan running, nothing happen because green in fan relay no receive volts 24 volts

what is you install a jumper between the C and G connector and install the G wire to the C connector....will you still be able to run the fan without the system running????

I have an old Mercury Thermostat with individual wires labeled W-Y-O-B-G-R, this Honeywell RTH9580 WIFI thermostat control board has the W-0/B on the same terminal. How should I wire this?

Is there a way to enable the fan to run separately when not heating/cooling? I need to circulate air when running an HRV.

Tried to install this on my furnace. NO C wire on the old thermostat. Was going to move the green wire from G to C on the furnace NO &^&**%* C terminal on the furnace, only a T. Not sure what this thermostat works on. My wife bought this thermostat. I am not sure why she thinks the Russians should be able to control the temperature of our house.

do you GUY'S respons the Poster?
