AC "clicking" sound while running furnace???

[BillATX]

Boondocking with no hookups in Elite 1.  Running the furnace.  Thermostat fan speed set to Auto.  

The AC fan is not running, but I am hearing a strange "clicking" sound coming from AC.  It sounds as if something is trying to cycle on/off... 

Any ideas?

Update - issue resolved.

I changed the temperature differential on the thermostat from "d1" to "d2".  As described in the owners manual, when the system is off, push the down arrow and power buttons at the same time and adjust from d1 to d2 setting.

I have no idea why the system would try to cycle the AC while in furnace mode,  but this resolved my issue.

Thanks to Mike Wyant on the FB group for the solution.
