Honeywell RTH230B Thermostat Wiring

[Spakman]

I'm attempting to replace a Robert Shaw electronic programmable thermostat. The following six wires are connected as follows in the unit:

Green wire to G terminal
Orange wire to O terminal
Blue wire to B terminal
yellow wire to Y terminal
White wire to W terminal
Red wire to jumpered RC & RH terminal

To be honest I don't know what type of system the HVAC unit is (i.e. heat pump, central air, etc - nor do I know how to tell by looking at it).

I have a Honeywell RTH230B electronic thermostat. Can this unit be used with the wiring above? If so, how are the wiring connections made? The honeywell unit has the following wiring connections:

Rh
Rc
W
Y
G

Thanks

The fact the you have O and B terminals could indicate you have a heat pump. Anyway, you have to find that out, because the RTH230B does NOT have heat pump capability.

Post the model number of your outside unit .
