Example:

 If the correct time is 1:35 PM,

position the dial such that the TIME
pointer will point midway between the 1
and 2 numerals on the PM side of the
dial. If a more precise adjustment is de-
sired, the best procedure would be to
push-in the pin corresponding to the up-
coming hour (in this example, the 2 PM
pin) and 

on that hour,

 slowly rotate the

dial until you hear the "click" of the
micro-switch.

3. 

Proceed to set the present day by ro-

tating the calendar DAY dial to position
the correct letter opposite the DAY
pointer at the bottom of the dial. (See
Figure 5.)

4. 

Next, rotate the STATION dial in a

counterclockwise direction to position
REST at the top under the STATION
pointer.

This completes the controller clock set-
ting.

SCHEDULING AUTOMATIC OPERATION

Before proceeding to set the automatic schedule, be sure the HOUR and DAY dials
are adjusted for the correct time and all pins are in the “out” position.

1. 

Push in the pin(s) corresponding to the day(s) on which watering is desired. Re-

member, each DAY pin represents a 24 hour period beginning at midnight.

2.

 Next, select the desired starting time(s) and push in the corresponding pin(s) on the

HOUR dial. Multiple “starts” within a given day may be scheduled after completion of
the time accumulated by the previous cycle; see 

NOTE 

following Step #3.

3.

 The first mark (square dot on the station dial) is the minimum time setting and rep-

resents approximately 3 minutes. The small white arrow moves with the knob for visual
indication of each setting. (There will be no valve output when the arrow is positioned
between "off" and the "square dot'') The ratchet notches represent 1 minute incre-
ments for precise settings. The OFF position at each timing dial omits the station from
the schedule.

SETTING THE CONTROLLER

With the main power ON, proceed to adjust the clock for the correct time and day.

1.

 Put the MODE switch in the OFF position.

2.

 Rotate the HOUR dial (clockwise only) to position the current time opposite the

TIME pointer at the top of the panel. Observe the dial for the correct AM or PM numer-
als.
