This is perfect timing! We just bought a house with this exact old thermostat and had no idea how to update it. Nice to know it's actually pretty easy.
Hi there! Nest pro installer senior support rep here, with hvac units, of all kinds there is no standardization to the color of wires. there are common color configurations but at the end of the day, you will want to focus primarily at the wire label and use the color as a reference point. Hope that helps!
This is a "How to" guide and you're just fast-forwarding through the whole thing and saying to read the instructions provided by Google Nest. Not good.
So, how do we know which wire goes where? I have a Honeywell Modulation thermostat with 2 wires. How do I know where they go? They are labelled A and B on the Honeywell.
How do I take off the Honeywell thermostat? I see that you remove the outer ring touching the wall, but how is that done? A straight pull, or is there a twist?
Maybe next time explain what you're doing since your hand is blocking things.......or move the camera so your hand is not between camera and what your doing.
I have the same old device. After I install the new one, It comes with code N260. Meaning no C wire. Should we just ignore it? Basically, we fully depend on the AA battery, right?
It will constantly drain the battery and have connectivity issues. Also think it has caused my transformer to go bad. I am putting my old ones back in.
I have the two wires going to a relay in the basement that controls 240V baseboard heating. However the Nest needs continuous power. How can this be supplied? I have a green wire that is unconnected on both ends. Any way to use it?
With this ,your batteries do not recharge,and resultant messages you will receive from the nest will frustrate you no end...find another,more specific video...the two wire hookup ,needs more.
Ididnt complete setup... ithink itll work wont let me put address. but eh as long as heat works idc. Will just replace AAs and leave error code shouldve just bought another old honeywell. Old stuff is always better
I'm watching this video in reverse. Putting my old mercury Honeywell back in. Nest SUCKS! Constant issues with conectivity. Never should have wasted my money!
