I’m traveling in Europe right now and I have no clue how to use this. It goes from +5 to -5 and I thought it was hotter/cooler but I can’t tell and it’s generally hot in the room. Please help!
I am a novice female who has never done this before and I need help.
Removed nest to replace with Amazon smart thermostat.
Had to get c wire adapter.
I can power the thermostat. I can run the fan. But the condenser will not turn on!
Photos of wiring at furnace, wiring to adaptor and wiring to new thermostat. I wrote down what the wiring looks like left to right from furnace to adapter to thermostat.
Fuses are okay. I put nest back on it does run normally. So I presume it’s my wiring that’s wrong.
I have a delta brand thermostat in my office that the control the temperature of in a central office. Is there any way for me to like jailbreak the control in my office so that I can lower the temp and bypass the central office controls?
Hello! My condo’s previous owners installed a 24V thermostat that is incompatible with my 120V system. Does anyone have any good recommendations for a thermostat that matches this style of plug so I can get my cooling going with minimal construction?
Fan won’t turn off
Hello, would anyone know why after I removed my old thermostat (pic 1) to a WiFi one (pic 2) why the furnace/ac fan on a (Magic-Pak) stays running. I have the stat set to off and fan to auto. No matter what I do it stays running now. Grrr!
Hello, I was gifted a smart thermostat to upgrade the existing one in picture 1. I called an electrician to install the new one, he wired it like in picture 2 left and said he’ll be back another day. It’s not turning on and from my understanding the issue is that it’s missing a live wire. Is it correct and is it something easy to do?
Original Thermostat is a Danfoss 5000 and new one is Meross Meross MTS215B
So the old thermostat got hit by a door and the fan switch got knocked off so the ac wouldn’t blow. I looked up online and found people used this one to replace and he had the wiring diagram. Now everything seems to work except the ac isn’t blowing cold air. Please help cause it’s getting hot.
Is it my wiring? Did something get screwed up maybe if I wired it wrong? Etc etc.
Thank you all!!!!
I have no common available.
And no access to the rtu.
Couldn't I buy a 24v power supply and cap the red wire and hook up my new 24v and common then just hook up the new
thermostat the same way? Trying to put in a smart thermostat
Giving it a shot and seeing if anyone is aware of a programmable and phone controllable thermostat that works with no C wire and dual transformer (RH/RC jumper). I’m having no luck finding one.
Hello, I’m trying to update my thermostat to be one where I can change it on my phone and things like that when I’m out of town or just Mohr for convenience I wasn’t sure what thermostat that is affordable or Alexa compatible or anything. Anyone would recommend your pictures of the thermostat I have now cause I also don’t know like what would be compatible and how easy it would be to put in.
I can not get this thing to stop blowing hot air. Not sure what I’m missing. I’ve tried a few combos of the white and grey wires but it’s not working. I appreciate any help!
We had a Honeywell smart thermostat - wanted something that would automatically switch between heat and cool though, so we got the x2p. We do not have a heat pump. Picture 1 is the old wiring, picture 2 is the new wiring. The unit powers on, we have it set to cool and fan on, waiting about 5 minutes for the "waiting for equipment" message to go away. Nothing turns on though, the AC isn't running, if you set the fan to on it does not switch on. Help! It's getting hot in here ...
I have to leave for a family trip out of town in 6 hours, and my thermostat fell off the wall. I tried to replace it but I’m not sure why I’m having issues. I tried to match the colors of the wires with the kit corresponding colors but no luck. Did a little research and saw I had to V+ and Vg had to go to R and C slots. No luck.
The fans don’t turn on, neither the exterior unit or the internal. I’ve reset the breaker, I’m not sure if I need to match what’s in the AC unit in picture two. The only issue is the blue wire is extremely short, but could probably barely fit just snug enough to catch onto the gripper that’s holds the wire in place.
Any advice is great. Also happy mother’s day!
I want to upgrade to something WiFi controlled. One product had a comparability questionnaire, but it said further investigation is needed. Can I use a nest type thermostat?
I was also looking at these two:

Any help/advice is greatly appreciated!!
Attached is what our PREVIOUS Honeywell RTH6360 programmable thermostat was set to, so I thought it would be easy to set up the Sensi Lite....send help 😭 no matter what configuration we do it keeps blowing freaking hot air. It's 95° in our house but the thermostat is set to cool to 75
We were thinking HP / EL / O based on our old one but that doesn't seem to be working
White baseplate is old enough wire setup, black baseplate is current wire setup
Hello, trying to set up Nest because older thermostat didn’t have smart functions. My furnace and A/C are only a couple of years old.
When I hooked up the nest, I didn’t use the blue common wire because the old one didn’t use it.
Nest said it didn’t have any power, so I stopped the blue wire and inserted it into the nest but it still says it’s not getting power.
Went down to look at the control board on the furnace and there is a wire hooked up to the C terminal, but it’s not blue.
Not sure what to do. Any help is appreciated. Here are pics. Thanks!
Hey y’all, just removed my nest and went back to the old Honeywell. I thought I had marked all the wires correctly but I’m not getting anything out of it just powers on but will not turn on the ac or heat.
Markings are as follows
Red- RH in the R slot
Yellow- Y1 in the Y slot
Blue- C in the C slot
White- W1 in the W slot
Green- G in the g slot
All the wires are tightly secured. Any help is greatly appreciated!
I need to buy 3 thermostats for a new build. I have experience with Google nest platform for years. Kind of cumbersome and not very robust. Scheduling sucks, and the eco mode is crap.
I am looking for a smart thermostat that has an easy to use UI for multiple devices
It keeps saying that the c wire is undetected and that the g wire is unconfigured. But the thermostat works fine.
Hello,
We bought this home last year and it came with this Honeywell Thermostat and EIM (THM5421C). I hate the thermostat. I would love to upgrade to an Ecobee thermostat if possible, but the EIM obviously makes that more difficult than typical. With the current setup how feasible is it to bypass the EIM and install something new?
