Only two wires from wall to W and B terminal

When I wanted to replace my old thermostat with a nest learning thermostat, there are two wires from the wall connected to my old honeywell thermostat on the W and B terminals. There is a jumper from R to RC. How should I connect these two wires to the new nest thermostat? W to W1 but B to ?

Hi Andy66, 

 

Thanks for posting here in the Community forum and for showing interest in our Nest Thermostats. Are you located in North America or Europe? What is the make and model of your HVAC system and your current thermosat? Also, please share a photo of how are the thermostat wires connected to your HVAC control board so I can take a closer look. 

 

Keep us posted.

 

Best,

Zoe
