22 First Stage Override — If the current capacity s tage is zero, the control will modify the routine with a 1.2 factor on adding the first stage to reduce cycling. This factor is also applied when the control is attempting to remove the last stage of capacity . Slow Change Override — The control prevents the capacity stages from being changed [...]

23 Ramp Loading — Ramp loading ( Configura- tion  SLCT  CRMP ) limits the rate of change of leaving fluid temperature. If the unit is in a Cooling mode and config- ured for Ramp Loading, the control makes 2 comparisons be- fore deciding to change stages of capacity . The control calcu- lates a temperature difference between the control poin[...]
