STAGE SETTINGS

Modulating Mode - PARALLEL

•The Modulation Point should be set to the value where the unit runs most efficiently.

•Contact the manufacturer to determine the appropriate setting.

COPY SETTINGS - STAGE A ONLY

•If all the active Stages will have the same Ignition Start Point and Modulation Point, they can be set for Stage A and then copied to the other Stages.

•It is still required to select the Mode for all other Stages. The Mode will not be copied.

IMPORTANT: The Mode MUST be set for each stage. The Copy Settings command will not set the Mode for Stages B, C, and D.
