INSTALLATION
The Smart Clock can be installed in any convenient location since no external
power or light of any form is required It is however recommended that it not
be placed directly in front of sprinklers. For ease of installation, remove front
panel from box by unplugging it and loosening or removing two screws hold-
ing panel on left hinge. Use the following guide for new installations: 2
2 male adapter (not supplied) for PVC, or 2 x 2 male/female
threaded PVC adapter (supplied) for galvanized pipe.
Temperature sensor assembly
Screw and nut
to keep box
from rotating
2: galvanized
pipe or PVC
schedule 40
Side view
Concrete
2 galvanized sweep or
2 PVC schedule 40
NEW INSTALLATION:
Use either 2 threaded galvanized pipe, or 2 schedule 40 PVC pipe.
Dig hole with approx. dimension of: 12 x 12 x 10 deep.
Glue 2 PVC sweep to vertical PVC column. If galvanized pipe is used, thread on short piece of
galvanized sweep to galvanized vertical column.
Run wires through column and bend ends over the top for about one foot.
Set column in hole and use dirt to set vertical. Pour concrete around base for permanency.
If PVC pipe is used, place a 2 male PVC adapter through bottom of box after Knockout has been
punched out. Using a 2 conduit nut, tighten adapter to bottom of controller box.
Once concrete is set, pass wires through PVC adapter. Use PVC glue to affix adapter to top of PVC
pipe. Rotate controller to desired orientation.
Make connections as described in Terminal Wiring instructions.
For galvanized column, use supplied male/female adapter. Tighten nut securely.
To keep box from rotating, use guide hole in back of box to drill through lip of PVC or galvanized
pipe. Place screw and nut through this hole.
Mount temperature sensor assembly by passing wires through hole at bottom of box. Slide 3/4 inch
nut over wires and tighten from inside box with pliers. Screw down two wires from temperature
sensor securely to output terminals labeled T (Temp Sensor). There is no polarity to these wires.
Replace panel by screwing it into place with the two screws on the left hinge. Now plug in the
output connector.
Press any button and screen until screen comes up. In STATUS screen, the current temperature
should show on the top line. If it does not appear to be correct, check temperature wiring connection.

COMMON AND

TERMINALS
These are the output common terminals which are attached to the black latching solenoid
wires. Two terminals are provided for convenience.
These are the station outputs that each go to the red latching solenoid wires.
This output can be connected to a master valve or to the optional P.I.K. (Pump Interface Kit)
to operate a pump. In the Smart Clock, the sequence of operation is the master output comes
on first, then the master.
The temperature sensor leads are connected to these two terminals. No polarity
observation is required.
The common and normally closed rain switch terminals are connected to these terminals.
CAUTION; DO NOT CONNECT RAIN SWITCH TO COMMON TERMINAL
.
To connect rain switch, remove red jumper wire and connect rain switch terminals in
their place. The common and normally closed wires from the rain switch can be placed
in either R position.

CONTROLLER PROGRAMMING
STATUS: Push any button until display is activated. If display has been off more
than 15 minutes, STATUS screen is shown, otherwise, last active screen is displayed.
In STATUS, current temperature and today's temperature budget percentage are
displayed on top line. If output batteries are low, LO BAT is displayed instead on
top line. The bottom line shows rain switch activation, rain delay condition, if
temperature is below minimum setting, or if controller is off. If none of these four
conditions exist, enabled programs and active stations are displayed. A letter followed
by a number, such as B3, indicates that program B is enabled with station 3 on. An
enabled program must have watering day(s), start time(s), and at least one assigned
station with watering time.
TEST/MANUAL: To test valves, SELECT, ADJUST the time, and ENTER.
Every station assigned to any program will come on sequentially for one cycle for pro-
grammed test time. For manual operation, SELECT and ADJUST the station time.
SELECT again and ADJUST the station. Upon pressing ENTER, the master
comes on first, then the station. Upon shutdown, the station goes off before the
master. Only one station at a time can be operated manually. To terminate manual
operation, press SELECT three times until the station number flashes. ADJUST
the station number until OFF appears, then ENTER. TEST or MANUAL operation
will terminate any ongoing automatic or semi-automatic cycle in progress. If an
automatic start time occurs while in manual, test, or semi-automatic operation, the
automatic start is skipped.
SEMI-AUTO: SELECT and ENTER a program (A, B, C, or D) and all timed stations
assigned to that program will come on for one cycle. Only one semi-auto program
can be activated at a time. Semi-auto shuts down active automatic cycles.
