Features

• ESP: Extra-Simple Programming with self-prompting alphanumeric LCD display makes this controller easy to program, read and understand.
• Two independent programs (A and B), with three start times each, allow mixed irrigation applications in a single controller.
• System water budgeting from 10 to 200% in 10% increments makes seasonal adjustments quick and easy.
• Surge protection, backed by a 3-year lightning warranty, makes the controller reliable and robust under extreme field conditions.
• Station timing in 1-minute increments for precise watering requirements.
• Programmable 7-day watering schedule to meet varying irrigation requirements.
• Fixed 2-, 3-, and 5-day cycles for watering at regular intervals.
• Swing-open face panel for easy access to fuse and terminal strip.
• Manual start/advance capability for semi-automatic operation and system testing.
• Master valve/remote pump start circuit for optimal irrigation control.
• Battery recharging circuit maintains fully charged Ni-MH backup battery (included) to retain program memory during a power outage.
• Easy-to-understand AM/PM clock for quick reference.
• Durable, weather-resistant outdoor cabinet with internal transformer will hold up in tough environments.
• Sleek, modular design for clean-looking, professional installation.
• UL Listed; CSA, CE approved.

DESCRIPTION OF CONTROLS
Refer to Figure 1

1. 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.

2. DAY DIAL with 14 SCHEDULING PINS: The calendar DAY dial contains 14 captive 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.

3. 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.

4. STATION TIME CONTROL KNOBS: Individual TIME controls for each station. Timing is adjustable up to 60 minutes to suit all landscape growth requirements. A small white arrow moves with each knob along the timing scale on the Station dial (C) for visual indication of the time setting. The scale is marked-off in 5 minute graduations and the ratchet action of the knob provides for precision adjustment with each "notch" representing one minute increments. The OFF position eliminates the station from the watering schedule. All omitted stations are automatically rapid-advanced to the next timed station.

5. OPERATIONAL MODE SWITCH: The 2-position MODE switch provides the operating control for the system, AUTO position for automatic irrigation as scheduled and "timed" watering of a manually selected station. The OFF position is used for rainy weather shutdown. This position eliminates controller "output" to the system valves without interrupting the clock operation.

6. FUSE: 1.5 AMP (Slow Blow fuse) protects the controller from damage due to current overload. Replace fuse after the source of trouble has been remedied.

7. CURRENT STATION INDICATOR: STATION indicator identifies the current position of controller operation. See control (C).

8. CURRENT TIME INDICATOR: TIME indicator identifies the current time on the controller clock.

9. CURRENT DAY INDICATOR: DAY indicator identifies the current day of the watering schedule.
