WHM On Delay
WHM off Delay
Specifies the WHM On and Off time delays associated with the Next
ON VP and Next OFF VP menu options. Therefore, if the Next ON VP
or Next OFF VP is at its preset Valve Position (%) for the specified
Delay period, another heater will be turned ON or OFF. This is done
to prevent cycling units on and off during short changes in load.
