Is my thermostat compatible?

Hey folks,

I just moved into an apartment that has an old Honeywell thermostat and I'm trying to figure out if it's compatible with a Nest thermostat.

I looked at the documentation and I think the answer is no, but I want some input from other before I give up.

Below is a picture of what's behind my thermostat panel. To me it looks like what Google refers to as "Your thermostat has thick, stranded wires connected by wire nuts." but maybe I'm wrong?

Thanks!!

Hey, I actually went ahead and got the Nest thermostat but it's not working for me. So far I haven't been able to resolve it.

2 notes about my situation:

- I am in an apartment building without access to the furnace.

- I only have heating connected to the thermostat with R and W wires coming out of the wall. No C wire.

 

I initially connected the R and W wires to the Nest thermostat upon installation. I then received an error code saying I'm missing the C wire. After a while the power for the thermostat just ran out and I started seeing a "no power" message.

Since I don't have access to the furnace to connect the Google power thingy, I got a c-wire adapter that is claimed to work with Nest thermostat. I disconnected the original R wire and left it loose and connected the 2 wires from the adapter to the R and C ports. At this point I have 3 wires connected - R and C (coming from the adapter) and W (coming from the wall), The thermostat has full power without any errors or messages, but it doesn't seem to be controlling the furnace at all. I set the temperature and no heat comes out.

The furnace is definitely gas operated but I'm not sure what type it is. I tried both Forced Air and Radiator. Both don't seem to be doing anything.

Any ideas?

Hey there,

I'm so sorry for the delay in our response, but I wanted to hop in here to make sure we addressed your concern. I can definitely understand the confusion when it comes to thermostat issues as it can be very odd to figure out sometimes, but I'm happy to look into this for you. 

 

First off, I would suggest using the Compatibility Checker to see if your system is compatible. Then, if it is, I would suggest contacting a pro to come out to help you with this since I know that the Nest thermostat is not compatible with stranded wires, every wire has to be connected to the Nest Thermostat system. 

 

Please let me know if you have any further questions or concerns as I'm happy to help. 

 

Best regards, 

Garrett DS
