Remote Mode
The Remote mode is only available if the Remote option is enabled. It is primarily
used for systems where another control system is responsible for starting, stopping,
and capacity control. Remote mode uses an external Remote Start/Stop input and
Remote Load and Unload inputs for capacity control. A set of discrete outputs are
available for remote status information.
Auto-Remote Mode
The Auto-Remote mode is only available if the Auto-Remote option is enabled. It is
primarily used for systems where another control system is responsible for starting
and stopping the compressor but cannot directly perform capacity control. Auto-
Remote mode uses the external Remote Start/Stop input and Remote Setpoint selec-
tion inputs for capacity control.
Sequenced Mode
The Sequenced mode is only available if the Sequenced option is enabled. It is used
in M&M control systems where a master sequencer controller is responsible for start-
ing and stopping multiple compressors in a system. Capacity control in Sequenced
mode is performed by the compressor based on setpoints and control parameters
sent by the master sequencer.
