Setting Max Number of Stations ON
at the Same Time
• Press the button to access the controller’s settings.
• Press the or button to select MAX STN ON. The TEMPUS controller can
turn ON a maximum of 2 valve solenoids at the same time, that is:
1 station with MV or 2 stations without MV.
Press the or button to select:
1-V YES-MV, 1 valve and master valve
2-V NO-MV, 2 valves and no master valve
Important note 1: selecting 1-V YES-MV a Program A or B that is automatically
or manually started while a watering cycle of the other Program B or A is in progress,
will be delayed (stacked) until the current program’s watering cycle is finished.
If this happens, it may appear that the sprinklers are not shutting o or that they
are running at an unexpected time of day. To avoid stacking, make sure that each
program A or B watering cycle will be able to run completely before the next start
time of the other Program B or A occurs.
This can be easily determined by totaling up the run time duration of all stations that
will operate during the program (A or B), then selecting for Program B or A, a start
time that can accommodate the completion of the initial watering program. If water
budget is used to increase run time duration, this must also be considered in the
total run time. Refer back to this information when setting program start times as
described on page 12 and water budget on page16.
Selecting 2-V NO-MV a Program that is automatically or manually started while a
watering cycle is in progress will be started. If this occurs, make sure there is enough
water pressure to eventually run two dierent solenoid valves at the same time.
If not, select 1V YES-MV.
Important note 2: when setting more than a start time for the same Program
(A or B), make sure each start time is set after the previous irrigation cycle is
completed; otherwise the start time will be discarded.This can be easily determined
by totaling up the run time duration of all stations that will operate during the
program, then selecting the next start time that can accommodate the completion of
the initial watering cycle. If water budget is used to increase run time duration, this
must also be considered in the total run time. Refer back to this information when
setting program start times as described on page 12 and water budget on page 16.
Setting Seasonal Water Budget
The TEMPUS controller has been pre-set to automatically adjust the budget to follow
the average seasonal weather changes. A dierent value of a budget is set every 10
days of each month for a total of 36 dierent budget values for the whole year.
• Press the button to access the controller’s settings.
• Press the or button to select SEASONAL
• Press the or button to select:
SEASONAL OFF,
HEMISPH-N On, if the controller is in the Northern Hemisphere,
HEMISPH-S On, if the controller is in the Southern Hemisphere.
