Generally speaking, thermostats are not the reason for no-heat/no-cool calls. Yesterday was the second time, within six months, that the Nest was the culprit. I have a hard time believing that the stats were really the issue, seeing neither stat was more than one year old, however... The systems worked alright when hardwired (both times, the common was hooked up).

Obviously, I need to get edumuhcated on their setups, and plan on getting "certified" next week. Just wondering if anybody has had a higher than usual number of calls in which this brand was actually the culprit.

I have installed only 4 of the nest stats and zero issues with them upto yet. The one in my place has been in since release. They have such a sweet diagnostic system its bit hard for anyone to install them.

They were customer installed. I just don't know the configuring part, and they didn't have the paperwork. It did seem straightforward, and, it looked as though, at least in yesterdays situation, the stat was calling for heat, but, nothing going back to the furnace.

When hardwiring at the wall, heat came on, as well as re-installing customers original stat.

it should have a setting in the menu under equipment that will show you if there's any issues with the connections. heres a pic of what mine shows. the newer ones may be different but as long as its showing its connected when you call for heat or cool on that stat then it should fire up. they are almost idiot proof. their customer service is also top notch. you get someone who knows their stuff when you call.

Thanks :jester: As mentioned earlier, I think this one is alright, but, "it looked and sounded like a duck". Somewhere, we got to the section where it indicated that power was going to the stat.

r wire was connected to rh, not rc. Usually, those are jumpered, and that would make sense as to why system would not fire up under cooling. This was a late night call, and .... gotta do some homework on this one, as I am starting to notice these stats more frequently.

I thought that too but it says in the nest instructions to not jumper Rh to Rc. It says it does that internally
