A. HOUR DIAL with 23 CYCLE START PINS:

  The HOUR dial contains 23 pins for

scheduling automatic "Starts" on any hour (except midnight—which is day changeover
time). Embossed characters provide quick identification for each hour, AM or PM,
noon and midnight. Captive type pins are designed for simple push-pull operation.

B. DAY DIAL with 14 SCHEDULING PINS:  

The calendar DAY dial contains 14 cap-

tive pins for scheduling irrigation everyday or any day within a two week range. Each
pin represents a 24 hour period beginning at midnight. Embossed characters are on
the dial, adjacent to each day of the week.

C. STATION SELECTOR/INDICATOR DIAL:

  The STATION selector/indicator dial

contains the timing controls (D) for each of the stations. The dial automatically rotates
during a watering cycle with the current station appearing at the top, under the station
pointer. REST indicates the system is off and no watering is taking place. The dial is
also used for manual selection of any station for semi-automatic operation.
