TIME SETTING
TO SET THE CURRENT TIME (AND DAY OF WEEK
ON 7 DAY UNITS), TURN THE MINUTE HAND
CLOCKWISE. DO NOT SET THE TIME BY ROTAT-
ING "OUTER" DIAL.
Turn the minute hand clockwise until the day of the week
(7-day timer) and the time of day on the outer dial is
aligned with the triangle marker on the inner dial (two
o'clock position).
Example for 7-day program dial Monday 10:30 AM. Turn the
minute hand clockwise until Monday 10:30 AM is aligned
with the triangle on the inner dial. The hour and minute hand
will show exactly 10:30.
Example for 24-hour program dial 10:30 AM. Turn the minute
hand clockwise until 10:30 AM is aligned with the triangle on
the inner dial. The hour and the minute dial will show exact-
ly 10:30.
PROGRAMMING
7-Day (SW, QRW Models)
The weekly program dial reflects the seven days of the week
and AM/PM imprints for each day.
The time switch is programmed by pushing the captive trip-
pers to the outer ring position for the entire period that the
load is to be turned "ON", i.e., two hours for each tripper on
the 7-Day dial. When the tripper is pushed to the inside, the
switch is in the "OFF" position.
24-Hour (ST, QRT Models)
The 24-Hour dial has quarter-hour divisions and AM/PM indi-
cations.
The time switch is programmed by pushing the captive trip-
pers to the outer ring position for the entire period that the
load is to be turned "ON", i.e., fifteen minutes for each trip-
per on the 24-Hour dial. When the tripper is pushed to the
inside, the switch is in the "OFF" position.
