Photo shows wiring as it currently is on the Honeywell Touch display t-stat. Heat and cool work perfectly.
I have W, C, G, R, Y wires only
I have a heat pump on the roof
Yes, I know the ac guys wired it cockeyed on the roof but I did verify with a tech while on the roof, the white wire truly is the C and the blue wire truly is the W
I set the app up in my Honeywell as a heat pump. Like I say, works just fine, has worked fine ever since I installed it.
I go to set up a Nest to get a little bit of a discount from my power company, connected W, C, G, R, Y. I left OB empty.
The Honeywell has W/OB on the same input. The Nest separates these.
I go through set up and it only blows hot air when cool is supposed to be ON. There are no real detailed instructions in the Google Home app. I recall seeing a question as to whether my heat was forced air. On my current honeywell t-stat, It looks like between those two questions, forced air or heat pump, it is set to heat pump.
I assume the internal honeywell on screen t-stat set up determines how the W/OB input is used for the W wire.
I guess three questions:
1. Do I use W or OB input on the nest with my W wire
2. What options do I choose during the google Home setup. It doesn't seem to ask me too many questions, unlike the honeywell total comfort app
3. Seems like the wiring is straightforward
I live in AZ, this is your standard run of the mill heat pump w/ no extra cooling or heating stages.
