Compatible or not with wiring

[Scooter4483]

Hi,

I’ve been on the forums trying to figure out if my current setup is capable of having the 3rd gen Nest learning thermostat. I have a Honeywell thermostat: Honeywell with the following wiring:

 

 

 

 

the following wires are used left to right:

W2, G, W, 2 C Wires, Y, and R. Also looks like there is a jumper from R to Rc.  

I had a professional tech come out and not sure who he chatted with but told me I have an air handler with zones in my condo building as there are radiant floors near balcony. I do have AC unit on top of building. But he said the thermostat does not handle zones. I think he knew a little but also didn’t know a lot. Interestingly the old Honeywell shows it is for zones and this nest shows it works with zones also so what gives?  Does anyone know if I can hook this nest up with the two c wires and jumper?  I did read that I should not connect more than one wire to a terminal on the google thermostat. Any advice would be appreciated. Thanks!

Hello Scooter4483,

Thanks for posting the photo of your thermostat wiring diagram. I'd be happy to take a look at your system's compatibility with the Nest Thermostats.

Nest Thermostats don't use jumper wires as they have one built into their displays. Also, Nest Learning Thermostats usually don't require you to have a C wire, but there are cases where you might need one. To be sure, please check your system's control panel to know how the C wire is connected. If possible, share with us a photo of it so we can help you out.

Regards,

Mark

I’m not currently at home to look into this. Maybe in a few days. What photo do you need?

How do you attach images?  Didn't know it has to be coded.

Hello Scooter4483,

Thanks for the effort you put into sharing the photos of your system. The 3rd generation Nest Learning Thermostat can be installed without a C wire. To confirm, is your system a heat pump? If so, the wire connecting from W would be on the O/B terminal for the Nest Thermostat.

Please let us know if you have more questions.

I do not know anything about the hvac system.  I live in a condo building in which the AC units are on the roof and boilers are in basement.  I have this 'furnace' in my closet in the unit.  Is there anything specific I can provide to find out if this is a heat pump?
