Thermostat wiring Ritetemp 6020 Hyperion TAM4 to Trane heat pump

All, thanks for this great resource. My issue is the airhandler is turning on the Aux heet and the cooling simultaniously. We have changed multiple settings and the fuse blows. The heat pump wires to the handler suggest Black (x2), orange, Red, Blue, Yellow. with the black(x2) to W1-White and combine all W1.W2.W3 together. I have one state heat and Aux heet. The air handler has YO,B,R,O,YI,G and again combine W1W2W3. the rite temp used to work with the old system ( changed out) B,O,W,Y,R,H,G. Since the 5A fuse kept blowing we disabled the heet side. Now that the temps are declined i need heet. my installer is not available. Is this solvable over the Net. Best. Tad
