Reset Type =4-20mA
MaxResetDT =XX.X° ° ° ° F
StrtResetDT=XX.X° ° ° ° F

Soft Load
InitialSLAmp=XXX%
SoftLoadRamp=Xxmin
Soft Load settings can be OFF or ON as determined from the Soft Load setpoint. InitialSLAmp is
the percent of full load amps that the unit starts to ramp up. SoftLoadRamp is number of minutes
(1 to 60) to load from the initial percent amps to 100 percent amps.
SET UNIT SPs (7)
Max/Min LWT Rates
Max = X.X° ° ° ° F/min
Min = X.X° ° ° ° F/min
These setpoints determine the maximum and minimum allowable rate of chilled water temperature
change. They may take precedence over loading rates based on the SoftLoad ramp.
