Nest compatibility

Hello, I would like to know if my wiring compatible is with the nest thermostat. There are only 2 wires coming out of the wall. A blue and a red one. I will add a picture.

Kind regards, 

Robin

Hi Robin.

Can you post what the other end of the red and blue wires are connected to or preferably the model number of the furnace.

Without that: If they connect to the R and W terminals in your furnace, and the furnace runs on 24v to the thermostat then the thermostat could control heat. It would charge by "power stealing" which you might notice as additional cycling of the furnace. Hope this helps.
