RE: [EnergyPlus_Support] Disable a DX coil below "xx" temp

I belive that the heat pump object itself has fields to turn off in the heating mode and turn on the auxiliry heaters.

Subject: [EnergyPlus_Support] Disable a DX coil below "xx" temp

Dear Forum,
I'm unable so far to figure out how to disable a DX coil in cold weather. The AvailabilityManager:LowTemperatureTurnOFF
seems to be the right tool for the job, but it's not doing anything the way I've configured it.
The short story is this:
* I want the Heat Pump to be available on one schedule (with fan running)
* and its DX coil to be UNavailable when the outdoor temp <12.8C
* I've made a separate schedule which is always "1" called "SchCpct_LowTempClgOFF" and assigned that schedule to the DX coil

Shown below is what I've done so far. Please let me know what I am missing! (For the record, the IO Reference and example files aren't clear to me. They seem to say that the manager affects a schedule, not a component)
