Auto-Cycle Test
Place a jumper from TEST 1 to TEST 2 on the Low Voltage Terminal Board.
The unit will run in each mode for 30 seconds, scrolling through all modes (relevant to that specific model). It will exit test mode automatically.
To go through test mode again simply remove (for ~2 seconds) and restore the jumper.
If the jumper is removed at any time during the test mode, the unit will stay in the currently selected mode for 1 hour (except for the defrost mode on heat pumps). After 1 hour it will automatically exit test mode and resume normal unit operation.
Only stages for which the unit is designed will be activated. All others will be skipped.
