HPC - Connecting AC Power

The outdoor model HPC comes with a pre-installed plug to allow the controller to plug in to
an outlet easily. In the event you need to hard wire (wire directly to 120 VAC), the attached
plastic grommet threads off easily and you can make the connection following the steps
below.
1. Route AC power cable and conduit through the ½" (13 mm) conduit opening on the left
side of the bottom of the cabinet.
2. Connect the wires to the transformer wires located inside the junction box. International
units are supplied with a built in terminal strip. Always use a UL listed conduit ½" (13
mm) male adapter when installing the AC wiring.
3. Insert the adapter into the ½" (13 mm) hole at the bottom of the controller. Attach a nut
to the adapter inside the enclosure.
4. Connect a 9-volt alkaline battery (not included) to the battery terminals and place in
the battery compartment in the front panel. The battery allows the user to program the
controller without AC power. Watering will not occur without AC power. Since this
controller has non-volatile memory, the program clock and calendar will be retained
