1-2 Control system energizes when fan is turned
on (See FAN SYSTEM START-STOP
CONTROL).
3-4 Zone mixing dampers modulate to maintain
zone temperature setpoint.
5-7 Hot water valve modulates to maintain hot
deck temperature setpoint.
8 MA temperature determines hot deck reset
schedule start point.
9 Dynamic graphic sequence display permits
the operator to adjust program setpoints.
Program adjusts hot deck temperature based
upon operator inputs.
10 Control program coordinates load reset,
temperature, and fan interlock programs.
