Nest thermostat?

[MikeYC]

What are your thoughts? I am looking at geeting one but I am being told by NEST that they do not support a Carrier Heat pump? I cant figure out why? A heat pump is a HP right?
Any body know a work around?

BTW i am not purschasing it. Rebate deal from the Electric company !!!!

You gotta give us more information than a "Carrier HP". It's true that a HP is a HP but the controller maybe different from generation to generation. I'm not an HVAC but if you give make/model, we can find the service manual and figure it out.

I don't own Nest but several of my friends have them ($150 each - 2nd gen Nest) and installed it themselves on split systems, non HP. The Nest is a simple thermostat using the typical 24VAC line that everybody have seen in the last decades. If the Carrier HP is using some other type of line voltage, you might have to trigger them differently using a few relays.

I have a first generation Nest and love it. Unfortuately, I just signed a contract on a new modulating furnace, with a proprietary setup. So my upstairs will not have Nest control.

Nest does not support ComfortNet either, so true compatibility with the highest-end furnaces is still a pipe dream.

Older carrier heat pumps do things backwards from other manufacturers in terms of low voltage wiring so the nest might not have the ability to control the system.

I came close to buying one, but after reading several reviews that the Nest does not have a hold temp function, which was deal breaker for me.

Nest learns so quickly, it can adjust to whatever you want. Plus it is really nice to know if you are coming home early you can use your phone to turn the heat up remotely. Conversely if you left with the heat up, you can turn it down. I would have one at my shop, but it does not do low temps. I can't remember, but I don't think it does below 50 degrees. As for the OP, it does seem to me that there should be a way to run anything off of the nest, check online for hacks.
