I've never wanted to take a hammer to a thermostat this bad until I found one of these, hot or cold should never be this complex

[denisefisher]

I'm a senior. Totally d not understand this unit even with you good instructions. Calling the HVAC company tomorrow to see if there is a simple thermostat. This is crazy!

[JesusIsaFlatEarther]

I thought this was the worst explanation I've ever heard, until I realized it was the worst thermostat ever made to explain how it works.

I don't know what I'd do without this... I'm a software developer and even for me this interface is maddening!! 😂

[OracleNil]

Who remembers the round thermostat that you just dialed????

Thanks so much for this! This is the seventh programmable thermostat we’ve had over the years and it is the only non-user friendly non-intuitive one we’ve ever had. I couldn’t program it, even with the manual, wasting over an hour of my time before coming to YouTube to see if I could get some help. I really appreciate you putting this out there for us. This thermostat should be discontinued altogether.

I'm a film editor working with complex software and I was scratching my head while freezing my butt off. Thank you! Great, straightforward explanation.

THANK I had my thermostat set on a temperature and it was on TEMPORARY HOLD. The desired temp setting kept changing and I could not figure out why. Your video showed me how to reset the thermostat to PERMANENT HOLD!!!! Thank You for taking the time to show us how to operate this!

[juanitaverma]

Thank you!! I have struggled with this thermostat and figuring it out. You explain well and all companies should hire you as one who clearly demonstrates!

[Relle]

THANK YOU SO MUCH!!! I’ve been so confused just touching random buttons and giving up after a while. You helped me!!!

Just got a new furnace today and this is the thermostat we got (big change from the dial type). The tech explained it to me pretty quickly and when I looked through the manual after he left couldn't make heads or tails of it. Thanks for this straightforward instruction.

this is the worst thermostat i’ve ever used in my entire life. i’m convinced they made this while on crack because why the fuck is it so complicated to turn make the house HOT OR COLD. my last house all you had to do with turn the switch to auto or on, then on the other switch it’s hot, cold or off. simple, easy, and not frustrating.

[gigigetsfit]

Thanks for the video. Can’t believe how easy this is… now. I don’t mess with the complicated stuff just adjusting the temperature, switching from heat to cool and fan from auto to on.

Extremely helpful! I found this thermostat to be much more difficult to program than my previous Honeywell, but this video answered all my questions - Thank you! It was thorough, well-paced, and very clear.

[judytaylor]

It would have been nice to have a tutorial on how to set the air conditioning temp since this was installed in the summertime. Still have no idea how to make it cool.

[pammoyers]

Outstanding. Took away all the mystery of this frustrating device. Thank you so much.

[stephaniekuchem]

Thank you. This helped me tonight. It was 80 degrees in here.

I have a Honeywell T4 pro. I came into my house today my heat was cut off but my fan was on auto and the house was burning up like a sauna. What's going on with my thermostat? Is there a way I can cut the fan off completely or should I just disconnect the fan wire from the T4 pro.

[bananashaveice]

Thank you for creating this tutorial! It was extremely helpful!

Worst thermostat in the whole entire world. I want to rip it off the wall and break it
