HVAC Default
This macro provides the factory default parameter settings for the AYK550-UH.
Factory defaults can be restored at any time by setting parameter 9902 to 1. The
diagram below shows typical wiring using this macro. When using direct speed
reference in AUTO mode or process PID, see "General Considerations" on page 30.
None (Default macro)
Note! YORK Drives are pre-configured using the "HVAC" default macro. Changing
user macros may require changes to factory control wiring.
