Clearing Programs From Non-Volatile Memory.

1. Press the SELECT STATION key (the display shows 1 and a group letter and the run time).

2. If the display shows 1A 10n, then Press the up Change arrow two or three times.

3. Press and hold both the ON/OFF key and the WATER TIMES key for 10 seconds. This will
cause the controller to revert to the default program.

4. The display should now show 1 A 10n

5. The time display should not be affected by clearing the memory.

Default Program.

The default program is as follows. All stations are on the A group, set to water beginning at

8:00 AM, 10 minutes per station, seven day cycle, water each day.
Common Misconceptions.

This controller is too complicated for me to program or understand!
This is an appearance issue. There is a short cut to the programming function that makes this an
easy to program electronic controller. *see DITTO section below.

Start Times
It is difficult to calculate the start times/station run times to get the controller to operate a series of
stations. Solution; If you program all of the stations with the same start time, the controller will auto­matically stack the starts and provide a sequential run, operating first the lowest numbered valve.
When it has run it's programmed time it will close and the next valve in sequence will begin.

Programs or Groups
This controller appears to have 4 programs, but this is not the case. The controller is capable of op­erating multiple valves simultaneously by assigning valves to A, C, D or E Groups (B is not used as
it looks like the number 6 on the led display) . The Group feature should be used only if the water
supply is large enough to sustain large flow volumes. To use this feature; Assign start times and wa­ter days to other Grouped valves that are the same. If you want group C to run with group D they
need to have the same start time and water days.

Group A (the designator used in the following example watering schedule) is in fact completely inde­pendent in action. In other words, any station programmed in the A Group has independent proper­ties and can be assigned different water days or start times than any other station in the A Group.
