Section 19 • Configuration

Compressor Sequencing

The compressor sequencing is a feature of the Vission
20/20 that allows the operator to setup as many as fi ve
compressor to automatically start, stop and maintain
system loads. The compressor that is designated as the
master will monitor systems parameter and make deci-
sions on how many compressor are required to meet the
load as effi ciently as possible.
Compressor Sequencing:
• Enables the compressor sequencing algorithms and
allows access to the compressor sequencing screen.
Master:
• Identifi es the panel as the master while in sequencing
control.
Slave:
• Identifi es the panel as a slave while in sequencing
control.

Compressor Name:
• Unique identifi er that is broadcasted to all other
Vission 20/20 units in the sequencing network.

Language

Allows the operator to select the language in which all
screens will be displayed in.
