Replacing old thermostat with Honeywell RTH230B
I recently purchased a Honeywell RTH230B thermostat and was all ready to start connecting it up when I found that the connectors appear to be a bit different. Before I mess something up, I wanted to make sure that I was doing the right thing. I have a Lennox Elite Series CB29M-46-1P unit connected up to a Lennox thermostat. The base board in the thermostat is marked with two labels: the one in the lower left indicates
"30V.A.C.1.5A, LR11746, Class 2, 9519"
While the one on the right indicates
"LENNOX, 78H2201, 3AAT89A38A2"
And it has connectors marked as W, B, O, Y, R, G while the wires coming into the thermostat are color coded as white, black, yellow, red, and green.
The wires are currently connected as follows: W is jumpered to Y, the black wire is connected to O, the yellow wire is connected to Y, the red wire is connected to R, the green wire is connected to G, and the white wire is disconnected.
My new thermostat has the following connections: Rh, Rc, W, Y, and G. My first question is whether the thermostat was correctly connected up in the first place. My second is, how should I connect up this new thermostat?
