DUCANE heat pump

I recently installed a DUCANE heatpump and the electric heat is comming on with the A/C. There is a jumper wire on the stat from w1 to y the connections on the stat are

W1 W2 C Y O R G the connections on the furnace are

W1 W2 C R G in the installers manual it tells me to hook both w1 and w2 from the furnace to the w on the stat but when these wires are connected the electric heat is powered think i imght have to pull the jumper on the stat and split my w1 and w2 from the stat to the furnace??????????? Any of this sound correct? Any hints helpfull!!

Heat pump problem

The y on the thermostat activates the compressor, either for heat or for AC.
Depending upon how your airhandler is wired, the W1 should activate the electric heat when needed. If it is jumped to y, it is coming on whenever you call for heat or AC. This is not correct. You should disconnect the jumper and ensure that the W1 connection does indeed feed the electric heat relay or sequencer.

The o terminal is usually the activator for the reversing valve and w2 is to
the second stage heat.

How many KW of electric heat do you have?
