Thermostat Wires don't match-help please
Sir or ma'am-
I am attempting to replace my 1960's era Honeywell thermostat with a modern 5-1-1 and I managed to thoroughly confuse myself.
My 1930's era house only has gas heated radiator system connected to this thermostat. We added central air 6 months ago but it is on a separate system. The old Thermostat had a clock in it that was powered by two wires.
Coming out of my house is Black, White, Blue, red and Green.
The Honeywell Thermostat has C, G, Y, W and Rc RH.
FYI if it helps, The old plastic plate says Heat On- R-B Heat Off R-W
I am not sure what this means but any help connecting would be appreciated. I had to use portable heaters because the heat isn't working and the kiddos are cold!
