MOUNTING THE CONTROLLER
1.
Install the controller and transformer indoors near an AC outlet. Once the site is chosen, drive
the provided #10 screw into the wail stud, leaving about l/4" of the screw exposed. If
necessary, use a toggle bolt or masonry shield.
Hang the controller from the keyhole in the back of the case. If further security is
desired, two additional screws may be inserted through the holes in the lower rear corners of
the controller case.
2. CONNECTING THE TRANSFORMER
CAUTION: Plug in the transformer only after the transformer leads are connected. See
wiring diagram on page 2.
Open the bottom access cover and route the two transformer leads through the small hole in
the bottom of the controller case. Insert one transformer lead beneath each screw then tighten
both screws securely.
3. CONNECTING THE BATTERY
Connect a 9 volt alkaline battery (not included) to the battery terminal. If no battery is used,
reconnect the battery terminal to the inside of the terminal strip door.
In case of a power outage, this battery will provide back-up power to retain the program and to
advance the clock. (NOTE: The battery does not contain enough power to operate the valves.)
A typical alkaline battery contains enough power for between 6 and 12 hours of power loss.
THE "FAIL SAFE" FEATURE: In the event a battery is not used and a power outage occurs, the
controller program will be "lost." Once power is restored, a "fail safe" feature automatically
returns the controller to Day 1 and the clock resumes running starting with 12:00 p.m. Then,
unless the controller is reprogrammed, at 7:00 a.m. a "fail safe" program comes on and waters
each station for 10 minutes every 24 hours.
4.
CONNECTING THE VALVES
CAUTION: Before connecting the valves, make sure the transformer is unplugged.
Route one lead wire from each valve through the large hole in the bottom of the controller case.
Insert under the screw terminal strip. The "ground" wire from each valve should be attached to
a single "common" wire. Route this common wire through the large hole and connect it to the
terminal strip screw labeled "COM."
NOTE: This controller is designed for use with 24 VAC, 5 VA solenoid operated valves. A
maximum of two valves may be connected to any one station but no more then 3 valves (or
solenoids) should be operating at any one time. This includes the master valve if one is being
used. Current requirements should not exceed .32 Amp. for each solenoid.
5.
CONNECTING A MASTER VALVE OR PUMP
To use a master valve which operates throughout the watering run times, simply connect one
solenoid lead wire to the terminal strip screw labeled "M", and the remaining lead to the
terminal strip screw labeled "COM."
NOTE: The master valve must be equipped with a 24 VAC, 5 VA solenoid. If a pump is to be
used, connect a relay lead to the same terminal used for the master valve connection. The
pump relay should have a nominal coil voltage of 24 VAC at ,254 Amps maximum.
CAUTION: If you are using a pump start and pump start circuit, the "fail safe" progrram will
activate the pump for each of the six stations for 10 minutes each. If less than six stations are
being used, the pump will be running against a "dead head" on each unused station. This can
damage the pump. To avoid this, simply connect a jumper wire from the unused station's
terminal over to a station terminal that is being used.

NOTE: The controller is based on 24 hour "Military Style" time. Hours O-11 are A.M.; hours 12-23
are P.M.
The display always indicates the current time unless a station or program is on. See illustrations below.
After there has been a power outage or after the transformer has just been plugged in, the display
will flash as 12:00 p.m. or the current time, depending on how long the outage was. To stop the
display from flashing, just press the +/- Buttons.
