Nest thermostat setup- E wire

[thebaymes]

Trying to set up my nest thermostat and I have an E (emergency) wire that I don't know what to do with. The label said E/* so I put it in the * spot, but the thermostat registered it as a humidifier or dehumidifier.  Where do I put this E wire? Confused.

Hi thebaymes,

Thanks for reaching out. Based on the photo of your current thermostat, it's possible that you have a dual fuel system. You have a dual fuel system if you have a furnace inside of your home, and a heat pump on the outside of your home. Heat pumps look similar to air conditioners, so check the label on your outdoor unit to make sure it’s a heat pump. If you’re still not sure which system you have, contact a local pro.

If you have a dual fuel system, you will need to have a trained professional set up your thermostat. It’s important for a professional to assess the requirements for your specific dual fuel configuration since choosing incorrect options for a dual fuel system can result in damage to your system. Contact a local pro.

Thanks,

Edward
