Description

Default Value

CD-STATE (State)

Represents the current state generated by the sequence.

Satisfied

See Primary States (Occupied Sequencing [AHU MADD]).

Cooling Control Status

Value fed back from the mechanical cooling PID controller that is necessary for the sequencer to determine what actions to take.

Normal

Set Name: Control Status

Damper Control Status

Value fed back from the economizer PID controller that is necessary for the sequencer to determine what actions to take.

Normal

Set Name: Control Status

Fan Ready

Comes from the Start/Stop Sequencer and indicates that the fans and dampers have been sequenced properly.

False

Free Cooling Available

Output of the Economizer Availability module.

False

Preheat Control Status

Contains the value fed back from the preheat PID controller that is necessary for the sequencer to determine what actions to take.

Normal

Set Name: Control Status

Process Variable

Cold deck discharge temperature that is compared to the setpoint and used to determine whether preheating or cooling is required.

13 °C, 55 °F

Setpoint

Setpoint the state generator attempts to control.
