INDIVIDUAL STAGE ADJUSTMENTS

THE STAGE MENU

•In most installations, all Stage adjustments are the same, but each of the four output Stages can be configured differently if desired.

•If the stages are not set up properly, the Harmony operation may appear to be erratic.

•From the main display, press the STAGE button and release it.

•The Stage A Settings menu will be shown.

•Make all the appropriate settings for Stage A as described below and on the following two pages.

•After completing all the settings for Stage A, you have the option of copying these settings to all other Stages. Everything but the Mode -- Auto/Standby/Manual/Off/On -- will be copied.

•Then press the STAGE button to bring up the Stage B Settings menu and make all the settings. Continue until all four stages have been set.

•To move around the Stage Menus more easily, see pg. 29.

MODE	Default - OFF

Auto/Standby/Manual/Off/On

•The Harmony only controls the modulation of Stages set to Auto or (after a delay) those set to Standby. None of the other settings are recommended for output Stages connected to active units.

•Any Stage without an active unit connected, and/or without an output relay must be set to Off.

•The following list describes the MODE options:

Auto - The Harmony will control the Stage's operation to maintain the Set Point. Only Stages set to Auto can be Lead Stages.

Standby - Standby Stages can only be activated when all Stages in Auto have been at 100% modulation for a selectable period of time (see pg. 14). Standby is generally used when an older or less efficient unit is available, but is not desired to run except under extreme load conditions. A Standby Stage CAN NOT be a Lead Stage.

Manual - The Manual Mode should only be used when testing a Stage. Manual overrides the System Prove input (see pg. 6). The exact percent of modulation for a Stage can be set with the Manual mode. Once selected, the unit will immediately turn on and be modulated to the selected percentage.

Off - Any output Stage A through D without a relay, or not con- nected to a physical unit should be set to Off. The Off Mode can also be used to disable units which are being serviced.

On- The On Mode should only be used when testing a Stage. The On Mode overrides the System Prove input (see pg. 6). Once selected as On the Stage will immediately turn on and be modu- lated to 100%.
