    Thermostat / Heat Pump Challenge

    Hi,

    I'm a licensed contractor, , Ive installed around 15 Gas packs
    Now I'm installing a package heat pump and running into problems with wiring the thermostat for a york 2.5 ton Heat pump system with Heat Kit

    Ive got it wired up to a honeywell 3000 series thermostat, Using the 2H/1C config.

    Could you guys check my work for the thermostat wiring, Im not getting a response on the heat cycle, fan comes on fine.

    On the thermostat I jumpered E and AUX and connected it to W2 on the unit
    I wired B on the thermostat to C on the unit (per the schematic)
    From the unit to the thermostat G to G , O to O, Y to Y, R to R
    On the thermostat I left L and C open.

    Below are all the pertinent schematics

    so did I cross my wires? What correction do I need to make?

    TIA,

    Warhorse

    It`s better to be silent and thought the fool; than speak and remove all doubt.

    On the heat pumps terminals

    Heat pump = Unit

    will this work?

    B on stat to C on unit is dead short when you call for heat.

    I would agree that jumping W1 to W2 will get your electric heat on.
