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

Yes read the diections. You did not even post the model number of the new thermostst. Are we supposed to be mind readers. Post the model!

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.
