SYSTEM SETTINGS 1

AUTO ROTATE Default - Time

The Lead Stage will always be the first stage activated when there is a call for output.

Automatically rotating the Lead among the active stages promotes more even wear on the Stages and can help prolong the life of each unit.

The Lead Stage is shown on the main display in brackets.

The Harmony has three selections for rotating the Lead Stage. Each is described below.

Manual

If Manual is selected, the Lead Stage will not automatically rotate.

In Manual, whichever stage is presently the Lead Stage will remain the Lead Stage until there is a power failure. Then the Harmony will revert back to the lowest Stage in Auto Mode (that is, A first, then B, C, or D).

Time

On power up, or any time the Harmony loses power, the Lead Stage will be the lowest stage in Auto Mode (that is, A first, then B, C, or D).

If the default 24 hour rotation is used, at 2 am every morning, the Lead Stage will change to the next stage in Auto Mode. Note: If you do not set the system time (see pg. 21), the Harmony will assume it was installed at 2 pm.

If the Rotate Time is changed (see pg. 20), the Lead Stage will change to the next stage in Auto Mode every time the Rotate Time has elapsed. For example, with a 12 hour Rotate Time, the Lead Stage will rotate from A to B after the first 12 hours of operation, and then from B to C after the next 12 hours, and so on.

The Lead Stage will always be the first stage brought on and modulated when there is a call for output. As more output is needed, additional Stages are added.

When less output is needed, the additional Stages are turned off in the reverse order of how they were added. For instance, if the stages were added in the sequence A, B, and C, then they will be turned off in the sequence C, B, and finally A.
