NOTE: Regardless of the specific
watering run time you select for a
Station, your controller will wait
the maximum run time setting
possible before watering will
begin in the next consecutive
Station. For example, if you
select a run time of 15 minutes
for Station 1, your HRM4 or
HRM-4i controller will wait 30
minutes (your HRM-6 or HRM-6i
15 minutes) before watering will
begin in Station 2.
Manual operations and shutoff
A. For system shutdown in case
of rain or other reasons, move
switch to OFF. This turns off
power to valves while clock
continues to keep time.
B. For manual operation, first
move switch to OFF. Rotate
Station selector knob until
desired Station aligns with dot on
chassis, then move switch to
MANUAL. The Station will water
and indicator light will remain on
as long as controller is in manual
mode. You must shut off
watering manually by resetting
the selector knob to another
Station or switching to OFF or
Automatic positions.
NOTE: After manual operation,
always turn Station selector knob
so index arrow points directly at
time dial, then move switch to
AUTOMATIC or OFF.
