    Lennox to honeywell thermostat
    Im trying to replace a lennox therostat with a honeywell - the heat is working but the air is NOT

    When I wired the new thermostat the wire marked with w1 and o from the lennox did not match up - the instructions showed the wires both going to the same place - I hooked up the w1 and taped off the o

    Any suggestions please

    If you have a heat pump O is the reversing valve, it energises the reversing valve in cooling mode for most systems. Give more info if you can.
