I'm replacing my old trane weatheron heat pump thermostat with a digital non-programmable honeywell heat pump thermostat. I can't seem to get wiring to match. The old on is a 3AAT80B1A1 . The Honweywell is a RTH3100C model. I have all the color-coded wires correct. I'm having trouble with the E, AUX and L.
