Wiring for V155A52C9 for new Nest thermastat
I own a 1929 house with a gravity gas furnace.
When I first moved in in 2002 I changed the thermostat to a digital thermostat.
I recently purchased a Nest Learning thermastat with hope that if my job doesn't get eliminated I will
have a new furnace installed in a few years.
My problem is that my honeywell digital had 3 wires connected to it.
The black wire was connected to W, the white wire was connected to R and the red wire was connected to B.
I am not sure if B was the right connection bit my furnace worked.
Yesterday I pulled the valve cover so that I could swap the old thermostat wires with new.
Any help would be appreciated.
