= SAVE KEY, FOR A RATE OF CHANGE FACTOR OF .10.

THE AVAILABLE RANGE IS FROM .01 TO 2.00

This code allows you to set the speed of the counter that was explained in code 17. The Rate of Change Factor directly influences how fast or slow boilers are brought on line when heat is called for. If boilers are brought on line too quickly, a waste of fuel can result due to too many boilers running and short-cycling. Too long a count between boilers may result in unsatisfactory heat to the building. TRIAD recommends an initial setting of .10. The lower the factor, the longer (slower) the response time of the boilers, and the higher the factor, the shorter (faster) the response time.
