Wiring question

[BD333]

My son just bought an older house with baseboard heat (oil furnace) and a central air ac system. There are several old thermostats some controlling one system and some both. The one we're trying to replace controls both heat and air. It has a white wire connected to W and a red wire connected to RH with a bridge wire to RC. Is this compatible with the E thermostat and if so what is the correct way to wire it. Thanks.

Hi there!

@BD333, thanks for posting in the community. I'll be more than glad to help you. It seems that your system is compatible, but I want to be sure about it. 

• Could you please send a picture of your thermostat’s configuration? 
• About the bridge connected between the RH and the RC terminal, you can remove it because the "Nest Thermostat E" won't need it. 

In the meantime, you can take a look at the following article: Install Your Nest Thermostat. You will find a compatibility checker and also find videos about how to install the thermostat.

I’ll be waiting for your reply. 

Regards, 

Derick.

Well you can tell it's my 1st post - couldn't find a way to attach files.

"Figured it out" only meant I found out how to send the pictures of the thermostat you requested.  Sorry for the confusion - still looking for help on my original question.

Hi @,

I do apologize for the confusion too. Thanks for your reply and clarifying the situation about the thermostat compatibility. Yes, your system is compatible with the Nest thermostat E; the recommendation is to remove the bridge between the RH and RC terminals because the Nest Thermostats don’t need it. 

If you need more information about installing a thermostat, you can see the following article: Install your Nest thermostat.

Please keep me posted if you have any other questions.

Best regards,

Derick.
