The following table describes the attributes used by the Plant Sequencing-Building Load modules:

Table 1. Plant Sequencing-Building Load Attributes

Name

Type 1

Description

Default Value

% Deadband

 

Indicates the percentage of the Stage Capacity that separates the Stage Up and the Stage Down.

5%

Control Status

 

This returns a status of the System Enable.

Off

Down Delay

 

Indicates the minimum time after a Stage Down that another operation (Stage Up or Stage Down) can be performed.

10 Minutes

Load

 

Indicates the amount of the load a single stage can satisfy.

0 btuh or %FLA or Amps

Minimum Running Devices

 

Indicates the minimum quantity of stages to run as a first stage.

0

Number of Devices Running

 

Indicates the number of devices that are currently being called by the BO sequencer to run.

0

Output (Float)

V

Indicates the number of devices that are being called to run.

0

Stabilize Delay

 

Prevents debounce in staging up or down.

180 Seconds

Stage Capacity

 

Determines whether Stage Up or Stage Down is required and is the variable that is compared to the Stage Capacity and the number of devices running.

0 btuh or %FLA or Amps

Start-Up Delay

 

Prevents staging until system reaches equilibrium.

60 Minutes

State

G

Indicates the current state.

Off

Set Name: Plant Sequencing Mode

System Enable

 

Enables the staging process to run using an Off/On command.

Off

System Interlock Status

 

Indicates the status of the interlock. The Global System Interlock Status must be On before any staging can occur.

On

Up Delay

 

Indicates the minimum time after a Stage Up that another operation (Stage Up or Stage Down) can be performed.

15 Minutes

1 C - Configuration Mode Only, G - Default Element (Generated State, if applicable), SC - Simulation and Commissioning Modes Only, V - Calculated Value (Outputs)
