Appendix 2 – Advanced Adjustment Features

There are multiple adjustment settings in the software.
1) Seasonal Adjustment, which can be individually set for each month (NOT if using Scheduling

Advisor)
2) Schedule Seasonal Adjustment, which adjusts all station runtimes on the current schedule
2) ET Adjustment, which adjusts the ET value used in scheduling calculations
4) Zone Seasonal Adjustment, which adjusts the selected zone’s runtimes
This appendix will discuss each setting in detail.
Global Seasonal Adjustment
The Global Seasonal Adjustment (Figure A2.1) will adjust all runtimes

in the system. The adjustment value is downloaded and stored in the

controller. The adjustment values for each month are independent

of the others. Once the calendar day rolls over to the next month the

controller will automatically start using the current month’s seasonal

adjustment value.
If you check the box “All 12 Months” the seasonal adjustment value will

drop to 10% (minimum value) to reflect that the user wants to set all

the months’ season adjustments. If you select an individual month then

the adjustment value will reflect the current seasonal adjustment on

that month.

Schedule Seasonal Adjustments

(Advanced Seasonal)
The Advanced Seasonal Adjust Settings allows the user

to modify a whole schedule or specific stations.
The Schedule Seasonal Adjustment (Figure A2.2)

affects all stations that have at least one event on the

current schedule. The adjusted runtime is a simple

multiplication of the percentage with respect to the

station’s runtime.
The Zone Seasonal Adjust affects all events for the

selected station. The adjusted runtime is a simple

multiplication of the percentage with respect to the

station’s runtime. The seasonal adjustment for each

station can be accessed through the Zone Properties

(Figure A2.3).
If there is more than one controller in the system,

change the “Select Controller” option to display the

selected controller’s stations.
