I have an XL950 controlling a Trane XL20i with a 4TEE3C04A1000A air handler. When the system cycles, it runs for 5-6 minutes indicating "Cooling" is running. The system shuts off and the display shows "System Idle". After about 5 minutes the display then changes to displaying "Waiting" and the system will start its next cooling cycle in 5-10 minutes.

Why does the display go from "System Idle" to "Waiting" ?
Is it normal for the XL950 to cycle so frequent and run for a short time? ( set for 3 cycles)

Just curious why it goes to a "Waiting" status.

Thanks for all input
