Installing the Base Station
1. Open the wiring compart-
ment of the irrigation clock.
2. Set the Voltmeter to “AC
Volts”, sometimes “~V”.
Units will be in Volt-AC,
often “VAC”.
3. Place the BLACK lead from
the voltmeter on the irriga-
tion clock COM terminal.
4. Place the RED lead from
the voltmeter on one of
the irrigation clock’s AC
terminals.
5. If the voltmeter registers
24-30V, this is the (AC +)
terminals.
6. If the voltmeter registers
~0V this is the the (AC -)
terminals.
7. Attach the BLACK wire
from the wiring harness
“Power Bundle” to the
(AC -) terminal.
8. Attach the RED wire from
the base station wiring har-
ness to the (AC +) terminal.
9. That’s it! The wiring phase
of installation is over. Now
it’s time to check your work
to be sure that you can
control each valve.
10. On a simple installation,
like this one, you can simply
turn on power, then se-
quence the Irrigation Con-
troller to manually power
each zone. Confirm that
each zone turns on, and
then turns off, as expected.
If so, the wiring is correct.
IMPORTANT NOTE:
The correct polarity of the AC connection is critical:
INCORRECT AC WIRING CAN POTENTIALLY DAMAGE THE
BASE STATION AND INVALIDATE THE WARRANTY
Use of a Digital Multi-meter (Voltmeter) is required to
ensure proper installation.
