Y1 W1 Wire from older Honeywell to new RTH honeywell

My older Honeywell programable thermostat for my heat pump went bad, I purchased a new RTH 7000 series thermostat. All of the wires are right on from the old one except the Y1 W1 wire. This wire was connected to the Y1W1 in the older thermostat Where do I connect it to the new thermostat? Any assistance would be greatly appreciated.

The problem with the honeywell brand is that the only dependable units begin with TH not RTH the RTH is for residential and you can purchase those at a local home improvement store. Go on Ebay and spend the money for a quality t-stat. "you get what you pay for"

Typically the four thermostat wires are:

R = power (or common)
G= FAN
W = Heat
Y = Cool
