I bought a new digital thermostat at lowes to replace my current Trane mechanical thermostat. I thought it would be quick install, but I have wiring problem. The current thermostat has 8 wires hooked to it from the wiring out of the wall. The new thermostat only has enough terminals for a 4 or 5 wire connection. Do I need the extra wires? Do I need to purchase a new T-stat with a 8 wire connection? Can i just connect the 5 wires and forget about the rest? Any suggestions would be greatly appreciated.

Hello Jeff:
Your heat pump requires lines for the reversing valve which changes from heat to cool. It also probably has a supplemental electric heater and an emergency heater. If your new t-stat doesn't provide for those functions you will have trouble.
I would recommend going back to the Trane dealer and asking him for an up dated thermostat that will answer to the things you desire.
