Section 3 -
Stagger Reset - Enable conditions
Stagger Reset is only enabled when both Chilled Water Reset and Condenser Water Reset are running
Stagger Reset alternates between the chilled water reset and the condenser water reset calculations. When on, the program
first resets the chilled water supply temperature and calculates its impact on decreasing energy demand. It then resets the
condenser water temperature and calculates its impact on decreasing energy demand. This is a lead-lag approach.
If both chilled water and condenser water optimizer reset calculations are done simultaneously, the program would not know
whether the chilled water reset alone decreased energy demand, or the condenser water reset decreased energy demand.
Temperatures might be reset in the wrong direction.
