Operation Manual

Seasonal Adjustment

Seasonal Adjustment is used to make global run time changes

without re-programming the entire controller. To use the Seasonal

Adjustment feature:

1. Turn the dial to the SEASONAL ADJUSTMENT position.

2. The display will now show a ashing

number followed by a %, as well as the

bar graph which always remains on the

display. Press the

or button to

adjust the percentage of the seasonal

adjustment. Each bar on the graph

represents 10%. This feature can adjust

the controller from 10% to 150% of the

original program.

To view the adjusted run times, simply turn the dial to the RUN

TIMES position, the displayed run time will be updated accordingly

as the seasonal adjustment is made.

NOTE: The controller should always be initially

programmed in the 100% position.

When using a Hunter “Clik” weather sensor, the Seasonal Adjustment

value can be adjusted as described.

When using the Solar Sync

ET sensor, the Seasonal Adjustment value

is automatically updated daily based on the Solar Sync sensor. The

Solar Sync ET sensor measures weather patterns, determines the

optimal Seasonal Adjustment value, and then updates the controller

on a daily basis. This value can be overridden manually by pressing the

or buttons to the desired Seasonal Adjustment value. However,

it is important to understand that the manually adjusted Seasonal

Adjustment value will be replaced at midnight by the new updated

value from the Solar Sync sensor.

To revert to a manually adjusted mode, the Solar Sync sensor must be

uninstalled. See page 14 for instructions on how to uninstall the

Solar Sync sensor.
