Heat Pumps and Electric Heating - Weatherking compressor not staying on...

Hello,

This is my first post in the forum, and what a great forum it is! I installed a new thermostat and after blowing the transformer (don't ask), I installed the new one, and thought I had all the wires to the thermostat on correctly. This is a heat pump system with aux heat, and I have 5 wires total at the thermostat. I am currently hooked up as such...

W2 - White
Rc - Red (jumpered to Rh)
B - Blue
Y - Yellow (Jumpered to W)
G - Green

I turn the setting to "heat" and fan to "auto"...the fan comes on, however the compressor does not. If I go outside and push the reset button on the compressor it starts up and I get heat just fine, however once the cycle stops, the compressor does not start back up unless I hit the reset switch again.

Any ideas?

Thanks in advance...

The heating (W) and cooling (Y) thermostat leads apparantly are cross-connected. You must check the low-voltage control-wire terminals at the compresor, and, if possible, refer to the low-voltage wiring schematic which is affixed to an acess panel on the compressor.

The compressor absorbs heat for heating, and dissapates heat for cooling, which means reversing the compressor operation. The auxiliary (electric?) heat complicates the control wiring

Just what is the button you reset outside?????
is it a high head cut out????low psi on the freon???

I get heat just fine, however once the cycle stops, the compressor does not start back up unless I hit the reset switch again.

Actually I hope I have the terminology correct, and forgive me if I don't. This is the outside device with the fan. There is a red reset button on the outside of the case. When pressed, the fan starts right up like it should. I tried switching the red wire on the thermostat from Rc to Rh retaining the jumper wire between the two. I didn't think this would do much of anything, but I'm trying to eliminate things one at a time.

Filter clean?

The reset switch is a high pressure reset.

Has it had refridgerant put in lately (this year)?

Out of the box here. But if you hit high head on heat. It can be ,inside coil dirty, blower wheel dirty, filter dirty. Or over charged on freon this summer.
Rc or RH are just the same if you have only one transformer
