I have these old honeywells all over the house, glad that I can hopefully upgrade them easily! Thanks for the great informative video.

I have two of these also (I have a boiler), so my A/C is on one and the Furnace (baseboard heat) is on the other. I can’t find a breaker in my panel for the A/C, but I found one for the fan/furnace. I used my voltage pen and discovered no electricity to the second (heat) thermostat, but I can’t find a switch that confirms no electricity to the A/C thermostat. Ideas? It trying to die today.

I HAVE THIS EXACT SAME UNIT. SAME HEATING AND COOLING. THANK YOU FOR THIS VIDEO AND YOU JUST SAVED ME 400$ TO HAVE IT INSTALLED

Angel P says:

Thanks man helped out!

Bibah Videos says:

Do these wires hold electricity? If so would i have to switch off the electricity on the PCB?

Check Reality says:

Great, very clear video. I have the exact same thermostat and want to replace it. Is this a millivolt system ? How do I determine that as I believe it wont work with Nest E. Thanks

Brian Couture says:

So how did it end up going with the attempt at the 3rd Gen in the other zone? I suspect it didn’t work out without a C-wire….

Michelle Lewis says:

Wow, that seems very simple.

J-Prez says:

Are you able to disable the auto learning on the 3rd Gen?

codeine catnap says:

great video! do you know if I need to turn my power off at the circuit breaker before taking the honeywell thermostat off? I don’t want to get electrocuted!

david sanchez says:

Thanks for your video, it's very informative. How long does the battery for the nest thermostat will last and how do you charge it?

Don MacDonald says:

Great Video really informative.

Javier de la Vega says:

Really great explanation! I have a quick question.

How does the app handle having two thermostats? I just bought a house where one thermostat only controls heat and another controls a/c cooling. Would you have to set them independently in the app?

Lev Aks says:

Thanks. Very clear explanation.
