I am having trouble installing a new home thermostat. Any help would be apperciated.

I am going from a Robertshaw 9420 to a Hunter 44260. My AC unit is a Goodman CPLE30-1A which I think is a single stage heat pump but I'm not positive. Both thermostats say they run off 24V.

The wires coming into my current Robertshaw 9420 are C,R,Y1,W2,G,O

The wire inputs for my Hunter 44260 are Y1,W/B,Y/O,RH,RC,G with the RC and RH currently jumpered. It was already jumpered when I bought it.

I'm kind of comfused and the book that came with the Hunter doesn't clearly define how to hook it up. At least to me it doesn't but I'm not that smart when it comes to these things.

What wires go to what? Please help. Thanks

When you take it back, get yourself a good honeywell,, Hunter is junk
