I just wanted to point out something about the tstat, and I need to know how to properly wire this thing.
I wasn’t sure about this till I checked the specs, but apparently ADC required me to improperly wire my tstat to make it work…
Perhaps you can push this to ADC, and see what they say?
In a nutshell I have a heat pump with cooling and 2-stage heat, ADC forces me to wire the W2 as W, then determines it is a “single stage heat pump”, so then I have to have it changed to “2stage” via backend.
The problem is that it isn’t wired properly, and I dunno what that means (just changing it from single stage to 2 stage with the W2 wire in W terminal), as I don’t think just setting it to “2 stage” is the proper resolution, or is it?
Seems to me the proper fix is to wire it as W2 instead of W (without ADC throwing up “W2 cannot be connected without W” error) just as the wiring schematics show.
Notice the second stage AUX heat is W2, there is no W as it uses Y for first stage heat
ADC states W2 cannot be used without W (which doesn’t exist in my HP wiring), thus forcing W2 to be wired as W:
What’s the option here? A Jumper from Y to W, then wire properly to W2? Or does merely changing it to “2 stage” rewire the W2 (stage 2 AUX heat), W (stage 1 heat), and Y (stage 1 cooling) terminals (so that stage 1 heat/cooling is Y terminal, and stage 2 AUX is W terminal?
Thanks for any assistance.
