(Use expanding anchors in plaster or masonry if necessary).
Slip the slotted keyhole in the back of the controller box over the extended
screw [Figure 22].
Push a No. 8 screw (included) through the Bottom Mounting Hole [Figure 22]
in the controller box and tighten until the box is held firmly to the wall, but
do not over-tighten.
The Controller has separate compartments
for the AC line power input and the low
voltage outputs. You must keep the input
power and the low voltage in their separate
places when wiring the controller box.
The controller has a built in transformer that
must be connected to an AC line voltage
source. Check the back of the controller box
for power requirements. This connection
should be made by a licensed electrical con-
tractor in accordance with the requirements
of the National Electrical Code and other
state and local codes.
Wiring the AC input:
Caution: do not connect the controller to one phase of a there-phase power system
used by a pump or other electrical equipment.
The controller has a nipple-mounted external power connection [Figure 23].
Use this 1/2 inch (13mm) NPT nipple to connect the controller to a standard
electrical junction box that should be UL Listed (or equivalent) or comply
with IEC or EN standards (or equivalent).
Turn off the AC power at the AC circuit breaker and apply an appropriate
safety lockout. Verify that the power has been turned off to the installation
site using an AC voltmeter set for the correct measurement range.
Use power feed wire of 14 gauge (AWG) minimum with a temperature rat-
ing of 155 degrees Fahrenheit (68 degrees Celsius) or higher.
Install the conduit and associated fittings. Connect the AC electrical power
wiring to the source by following all the right codes and local standards.
Connect the junction box (not included) to the NPT nipple [Figure 23].
Connect the source power conduit to the entrance of the junction box, fol-
lowing all the appropriate codes.
Connect the source wires to the wires extending from the controller.
Take care to follow the correct color code. For USA: connect the Green for
Ground, Black for Live, and White for Neutral. Often the source ground
may be bare copper conductor rather than green wire. For Europe: Live is
Brown and Neutral is Blue, there is no ground connection required. Be
sure that all wires are connected to the proper source wire.
Make sure all connections are made with code-approved insulated connectors.
Be sure to place a weatherproof gasket and lid on the junction box.

1. Wiring the Electric Valves
If the distance between the controller and valves is under 700' (210 m),
use WaterMaster ® sprinkler wire or 20 gauge (AWG) plastic jacketed ther-
mostat wire to connect the controller to the valves. If the distance is over
700' (210 m), use 16 gauge (AWG) wire. The wire can be buried in the
ground; however, for more protection wires can be pulled through PVC
pipe and buried underground. Be careful to avoid burying the wires in loca-
tions where they could be damaged by digging or trenching in the future.

FIGURE 23: Connecting Controller Wires to Valves
Each valve has two wires. One wire is to be connected as the common.
The common wires for all the valves can be connected together to one
common wire going to the controller. The other valve wire is to be
connected to the specific station wire that will control that valve
[See Figure 23].
All wires should be joined together using wire nuts, solder, and/or vinyl
tape. For additional protection to waterproof connections, a WaterMaster
grease cap can be used.
To avoid electrical hazards, only one valve should be connected to
each station.
