times can go as short as 10% of one (1) minute (equivalent to six seconds) for nursery application or newly 
seeded lawns. 
Zone Test
By pushing both
σ and τ
arrows at the same time, a zone test starts with zone 1 to check if there is a bad
zone, a short on the wires, or a faulty solenoid. The test has a ten (10) second delay then counts down ten 
(10) seconds in the LCD, then moves to zone 2 and so forth. If a short exists, a bad zone # will be indicated 
on the LCD. If multiple zones are shorted, the bad zones will be indicated in the LCD. Bad zones will be 
skipped in the watering cycle and reported until fixed. 
Reset Button
If you wish to reset or erase all programs you entered, be sure the rotary dial is in the RUN/ALL MANUAL 
position, then push the RESET button (located just to the left of the PROGRAM selector switch) with a pen 
tip. Your controller will then contain only the factory-preset program. You can then reprogram the 
CALENDAR and any new schedules you wish. 
INTERNAL FEATURES
The terminal strip appears as follows: 
SW2 (Switch #2)
SW2 allows zones in Program C to run at the same time as zones in Programs A or B for drip systems when it 
is placed in the down position. In the up position the programs run in chronological (earliest clock time) 
order. 
ADDITIONAL FEATURES
No backup battery needs to be purchased. An internal lithium battery is supplied. The expected life of the 
battery is up to seven (7) or more years. The battery backs up the customer entered programs (memory) and 
clock time in the event of a temporary AC power failure. 
No fuse is required with this controller. It is state-of-the-art technology with automatic circuit surge 
protection, automatic restart, and override of a shorted zone. These features can give you greater confidence 
that you can go away on vacation and your yard will get watered. 
 
 
Your “Water Champ” controller will “stack” program start times and runs logically. Start times are 
chronological (earliest clock time) and run until a program finishes in the event you programmed longer run 
times than can finish before the next start time. You could also extend run times into another program with 
% watering/Water Budgeting. Your controller will stack or hold this second program and start it when the 
first start time program finishes. 
Programs could run past midnight (i.e. long drip system programs). The controller will cancel a previous 
days program when the first start time comes up on the next day. The exception to this is if WATER DAYS 
are set on SKIP DAYS and the ODD/EVEN feature is activated. In this case, any remaining program run 
time would be canceled at midnight so as not to be in violation of any water restrictions.
