    Here is your wiring diagram fir the new stat

    http://customer.honeywell.com/techli...it/69-1846.pdf

    What is the model and brand of the old thermostat?

    With that info we can compare wiring.

    NOTE: Is the jumper still on RH and RC?

    There is a time delay for the A/C to come on. Did you leave the thermostat set to A/C for 10 minutes or more before saying it did not work?

    Does the blower in the furnace come on when switched to A/C at the thermostat?

    Did you check the breakers inside and the fuses outside to make sure there is power to the outside unit?


    Thermostat note from the instructions.

    Cooling system
    Does not respond
    (“Cool On”
    Appears on
    Screen)
    • Check for 24 Vac at the equipment on the secondary side of the transformer
    Between power and common. If voltage is not present, check the
    Cooling equipment to find the cause of the problem


    • Check for 24 Vac between the cooling terminal (Y) and the transformer
    Common. If 24 Vac is present, the thermostat is functional. Check the
    Cooling system to find the cause of the problem.

    Check for loose or broken wires between the thermostat and the cooling
    Equipment.
