Another Thermostat Question

I'm replacing an old Honeywell digital thermostat with a new Honeywell RTH7000 series. Naturally the wiring designations are different. The system is a Rheem split system heat pump. I'm thinking the wiring should look something like this:
OLD---------------------NEW
G..................................G
C..................................C
R..................................R-RC
Y-W1............................Y
B..................................B/O
W2-E............................E-AUX

I'm a little concerned about the B/O terminal as usually one or the other is used and I see no way of selecting one over the other. Any ideas will be appreciated.

In the set up Menu, #190 to 1, then you will be fine.

I have a thermostat in the hallway. It is set for 70 and registers 80 and the heat comes on 2 to 5 times in a 15 min timeframe. It is an old thermostat. heat bill was almost $800 dollars and winter isn't over yet. What can I do to fix it.

If the temps are the far off, and old, you are best to retire the stat, and replace it with a new one.

You dont say what stat you have there. But if old you might look and see what the anticipator is set at?? Is stat level on the wall??? Any draft in or out of the hole in the wall behind the stat that the wire comes out of ??? If so plug it. Or you can get a new one like Jay said.
