[. . . ] Note: If an interval of "3" is entered today, the Timer will water for the first time today, and then again every "3" days. To select odd or even day watering, press NEXT. The cursor will move to either the odd or even setting, then press ENTER. To enter a new schedule, press NEXT. Turn the rotary dial to the TIME/DATE position [See Figure 3]. [. . . ] Working in conjunction with the rotary selector, the keys are used to set the time of day, watering time, watering days, start times, and other functions. FIGURE 1: Location of Controls on the Timer 3. Selector Dial This large dial makes it easy to see which function is currently selected and/or in which mode the Timer is set to operate. FIGURE 4: LCD Display with Start Time 4. Reset Button The reset button clears the time, date and user-defined programming but does not remove the factory installed fail-safe program. To prevent an accidental reset, the button is recessed into the panel and must be pressed with a small pointed object such as a pen or pencil tip. Water Duration for Program A or B Note: Both programs require watering durations to be programmed. Turn the rotary dial to ZONE DURATION position in either the A or B program. The display will show which program you have selected with an "A" or "B" and the - - cursor blinking at station "1" [See Figure 5]. (All stations cycle once, A program only) To activate stations assigned watering duration for the A program only, press the MANUAL key, followed by the NEXT key. This will activate stations with assigned watering durations in the A program only. To initiate this semi-automatic watering, press ENTER [See Figure 11]. (All stations cycle once, B program only) Notable Programming Features Two Watering Programs--Summary The Timer gives you the option of using one or both of the independent programs. Note that each station can independently be set to either A or B or both A and B programs. To activate stations assigned watering durations for the B program only, press the MANUAL key, followed by pressing the NEXT key two distinct times. This will activate only those stations with assigned watering durations in the B program only. Example: To set station 3 for five minutes, press the MANUAL key; then press the NEXT key five times to select the manual operation mode and advance to watering for station 3; using the + or - key, set the manual watering duration to five minutes; then press ENTER [See Figure 13]. Install the Batteries The Timer requires two AA batteries to maintain the time, date, and programs in case of AC power loss. In a typical installation, fully charged batteries should provide sufficient power for approximately three years of operation. Insert two AA batteries into the battery compartment. Return the terminal cover to its closed position. Assigning Watering Intervals for Program B Program B is used to water at specific intervals between days (1 to 28), or on odd or even calender dates. The Timer has a leap-year compensator and will ensure conformance to the odd and even schedule through the year 2100. Turn the rotary dial to WATERING INTERVAL. The cursor will blink to the left of the word INTERVAL [See Figure 7]. FIGURE 13: Manual Watering Station 3 for Five Minutes WTM230158 57114-14 rF_Eng. qxd 12/10/2002 1:50 PM Page 2 Each valve has two wires. One wire is to be connected as the common. The common wires for all the valves can be connected together to one common wire going to the timer. The other valve wire is to be connected to the specific station wire that will control that valve [See Figure 17]. All wires should be joined together using wire nuts, solder, and/or vinyl tape. For additional protection to waterproof connections, a WaterMaster® grease cap can be used. [. . . ] Use expanding anchors in plaster or masonry if necessary. Slip the keyhole slot in the back of the timer over the extended screw. 8 screw through each of the two holes at the bottom of the box into the wall [See Figure 15]. Automatic Valves Durable, non-corrosive plastic construction. Automatic valves are available in anti-siphon or straight valves with safe, low voltage. 2. [. . . ]
