My Tappan Heat Pump is not shutting down on heat cycle when temperature is reached. The original thermostat was long ago changed out with an Honeywell Heatpump thermostat. It didn't seem to work properly as aforementioned. We purchased a new White-Rogers Heat pump thermostat and are not sure where all wires should be landed. The Heat pump is agreeably a older Tappan (Model PHR 24-41 T). The thermostat wires are landed at a gang lug at the heat pump unit as follows.

C =
Y = Yellow
W1 = White
W2 = Brown
R = Red
G = Green
O =

The White-Rogers Heat Pump Thermostat has the following lugs.

G
R
L
X1
E
B
W2
Y
O

Logically if one follows the wiring scheme from the unit.

Then the only wire that would seem to be in limbo would be
the White thermostat wire since there is no W1 lug on the White Rogers Thermostat....Where does the white wire get landed on the thermostat ?
