Make sure controller dial is in “RUN” position. Increase the value on
the Water Adjustment scale (the default setting is 5). If you max out
the Water Adjustment scale at 10 and still require more seasonal
adjustment, move down one Region (from 4 to 3, for example) and start
at Water Adjustment setting 5. Solar Sync will immediately update the
Seasonal Adjust on the controller. If it is still too low, repeat the adjust-
ment until the desired seasonal adjust is showing on the controller.

Make sure controller dial is in “RUN” position. Decrease value of the

one Region (from 2 to 3, for example) and start at Water Adjustment
setting 5. Solar Sync will immediately update the Seasonal Adjust
on the controller. If it is still too high, repeat the adjustment until the
desired seasonal adjust is showing on the controller.
