    How to hook up a five wire thermostat
    I live in a mobile home. I have 5 wires coming out of the wall for the thermostat. Old one broke. It only had 4 wires. I bought a new Hunter digital thermostat. It has lugs for 5 wires. I hooked it up and removed the jumper between the last 2 lugs. The heat works, but the A/C does not run inside or out. What did I do wrong?
