Ive attached a drawing of exactly what I have. I am trying to install a new programmable thermostat on my HEAT PUMP. There are some color/labeling issues that I am unfamiliar with. Let me know how to hook this up. (I think I know, but want to be sure).
I have a York BHZ Heat Pump and a York LX Thermostat.

**ALSO, a recommendation for jumper J2 on the thermostat, which is RV=O for W1/O/B to energize in cooling or RV=B for W1/O/B to energize in cooling. Nothing in my heat pump literature regarding this.

Thanks,
Brad
Set jumper for RV=O.

HP Y to stat Y1
HP W1 and W2 to stat W2
HP O to stat W1/O/B
