Greetings,
I'm at about week 3 after my Trane heatpump/dual fuel installation. The installers have been back once already to 'fix' the system. They are coming back again tomorrow to fix their wiring screw-ups. My patience is wearing on this deal. Seems to me that following a schematic shouldn't be too difficult. Maybe it is. Anyway, here's the deal, by looking at the schematics on both the furnace (XV80) and my IAQ 9000 I see that W1 and W2 are jumpered as is the Y and O. I understand this is not correct. I also have no O to O from the furnace board to the tstat. I have a W1 to the W2-Aux on the tstat, but no W2 to the W3-Aux2 on the tsat. I'll get all those items dealt with tomorrow. Coming out of the tstat going to the heatpump is an orange W1-OB wire, a yellow wire off the Y terminal, and a white wire off the W2-Aux terminal.
My question, in laymans terms, is what does the white wire do coming off the tstat going to the heatpump? Honestly, I don't care what it does, but is it supposed to be there? Just looking at the rest of the W wires, they seem to be involved with furnace side of the system, not the heatpump. Given that these installers seem to have problems getting this righ,t I'm pretty skeptical they'll get this right, thus questions to you pros that I shouldn't have to ask at all. I guess the second question would be, what terminals off of the tstat should have wires headed out to the heatpump? (Excluding the outdoor temp sensor)
Finally, and I'll end this rant, I close up the bottom panel of the furnace after having drawn my "as wired schematic." A couple of hours later I note it seems a bit cool upstairs--that's the furnace I'd taken the lower panel off of. I look at the tstat face, it's dark. Hmmm, maybe I didn't get the furnace door back on. Check that, no luck, check and reset the CB, no luck. Thinking how I'm going to explain having totally screwed up the furnace. Just seems like the furnace is getting no power at all. In desparation I pull off the upper panel. There dangling is one of the 'hot' leads from the power box. It had slipped out of the wire nut, which appears too small for 3 wires. Checked the power off, got the wire back in the wire nut and now the furnace is operating again. I SWEAR I didn't mess with those wires when I was looking at the wiring from the furnace board to the tstat.
But damn, am I asking too much for a professional installation? Initally I'm dealing with a sales guy who seems very knowledgeable about what I need and spends a goodly amount of time answering my questions. Seems like a good operation. I check references--everybodies happy. Course they're probably not checking wiring against the schematics.
Sorry for the rant here. You guys who write on this forum are pros and I appreciate all of your help. I just wish the folks putting this system in had half your professionalism and your interest in doing it by the book.
Oh yeah, the question was about the wires coming out of the tsat. Please tell me what I should see. I want to make sure these guys get it right. I'm tired of having them as my house guests.
