STEP 1: CHOOSE TIMER LOCATION

Select an INDOOR location near a standard 120 volt AC electrical outlet (240 Volt outlet for 50 HZ
units). The location should be completely protected from moisture, direct sunlight and below freezing
temperatures.

 (Important: DO NOT plug in the transformer until you hove made all wiring con-

nections.)

WARNING:

 When choosing a location, to avoid possible damage to the timer:

• DO NOT install in area where temperatures are less than 32° F or higher than 120° F.
• DO NOT install on same wall socket as other high current draw products such as garage door opener,
   washer/dryer, air conditioner, etc.
• DO NOT install on outlet controlled by on/off switch.

HOW TO INSTALL

A

B

NOTE:

 You may install the timer using two screws aligned horizontally.

1.

 

Screw two #10 screws into the wall 3 1/2" (88 mm) apart leaving 1/8" to

1/4" (3.2-6.4 mm) of the head extended from the wall. If mounting on plaster or masonry walls, plastic
anchors may be required.

2. 

Place the two keyholes "A" on the back of the timer over the screws.

3. 

To further secure the unit, open compartment cover and place screws (1 1/4" minimum length)

STEP 3: CONNECT BATTERY

Connect a 9 volt alkaline battery (not included) to the battery terminal and place it in the designated po-
sition. 

DO NOT USE A RECHARGEABLE BATTERY

. In the event of a power outage, the battery will

temporarily preserve your Schedule (newly installed batteries can preserve programs for up to 1 month,
see note*). Watering will not occur until electrical power resumes.

(*

NOTE:

 Battery operates memory back-up only. You can program your timer with battery power only;

however, the system will not operate the valves while on battery power.)

DEFAULT MODE:

 Should the battery fail during a power outage, the timer will default to watering every

day for 10 minutes per station, starting 8 hours after the power resumes, until reprogrammed.

TIP:

 Replace the battery once a year at the same time you would replace household smoke detector

batteries. When replacing, do not unplug the transformer, or you will lose all programmed settings.

CAUTION:

 Do not allow the battery to come in contact with the wire terminal strip.
