CD-STATE (State)

Represents the current state generated by the sequence.

Satisfied

See Primary States (Occupied Sequencing [AHU 100% OADD]).

Cooling Control Status

Contains the value fed back from the mechanical cooling PID controller 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 whether the fans and dampers have been sequenced properly.

False

Heat Recovery Control Status

For proportional heat recovery devices, specifies the value fed back from the heat recovery device PID necessary for the sequencer to determine what actions to take.

Normal

Set Name: Control Status

Heat Recovery Modulated

Contains a configuration input used to tell the state machine if the heat recovery is modulated or not. True means modulated and False means not modulated.

False

Preheat Control Status

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

Normal

Set Name: Control Status

Preheat Percent Cmd

Position of the output controller. This attribute is used to prevent the preheat device from unnecessarily cycling off then back on as the air handling unit starts up.

0.0%

Process Variable

Contains the cold deck discharge air temperature. It is the variable that is compared to the setpoint and is used to determine whether it is necessary to heat or cool the discharge air.

13 °C, 55 °F

Setpoint

Contains the cold deck temperature setpoint the state generator attempts to control.

13 °C, 55 °F
