I'm trying to install a rth230B, but my wiring connection choices do not match up with my current T-stat wires. Note: My current digital T-stat is a power sharing model (ie. no batteries) and the rth230b uses batteries, so I have that difference right out of the box. I have a single stage gas furnace and single stage condensing unit.
The choices on the new rth230b are : G,Y,W,Rc,Rh.
The current wires/connections on my old T-stat are: C (blue), R (red) , W1 (White), Y1 (Yellow) and G (Green).
There is no specific guidance in the instructions stating where to attach the C (blue wire) and which terminal for the R (red wire), either Rh or Rc.
As you can tell I'm quite a novice at this, so I'm reluctant to use the trial & error approach.
Thanks,DA
