STGMODE PID P P
BOIL TARGET 180 180 180 This is for DHW setpoint demand - if used
OUTDR START 70 70 70
OUTDR DSGN -10 -10 -10 May be -20 or -30F depending on area design temp.
BOIL START 70 70 70 This is used in the calculation of slope
BOIL DSGN 180 180 130 Radiant - 130 Wet, 140 or 150F for Dry system
BOIL OUT MAX 200 200 150 Default 200 - Use "FACTORY" Dip Switch to Adjust
Can be set 10F over BOIL DSGN
