Customer Question
I just installed a...

I just installed a T3 thermostat and it works fine, but I can't get it to shut off when the house reaches set temperature

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

I think it's the thermostat because I have the top setting (small numbers) set at 74 and it's still running when the temperature reaches 78.

Contractor's Assistant: Do you plan on doing the work yourself?

Yes, I have gone into the mode and set the unit to off and fan to auto but it continues to run

Contractor's Assistant: Anything else we should know to help you best?

Not that I can think of

Hello, tell me please which color wire was attached to each lettered terminal on the old thermostat, and the same information or photo's on the T3.

.

There is most likely a wiring error that we can easily correct,

.

Use the 'add files' link next to your send button to get photos to me.

We can go from there without any time limits,
