Thanks in advance.

I've installed a Hunter Digital thermostat in my 1989 single-wide, and while the guy I bought it from said the A/C was new, the unit looks original to the place.

The thermostat controls the heat, but when I switch the unit (no the thermostat) to cool, the fan runs continuously and does not respond to the thermostat. I've jumped Rc and Rh with a red jumper, put the white wire on my W terminal, and put my red wire on my Rh terminal. My terminals are W RH RC G Y/Y1 O/B.

I have no idea what to do. Again, thanks a lot in advance--the Alabama summer's coming and we need the A/C to run but with this problem it runs all day.
