Back Module Installation
1. For safe, reliable operation, select an installation site which can ideally provide
the following conditions:
• Inside a garage or other structure which will provide protection from the
weather.
• Access to a grounded AC power source (within 1.2 m) which is not controlled by
a light switch or utilized by a high current load appliance, such as a refrigerator
or air conditioner.
• Access to the sprinkler control valve wiring and optional accessory wiring.
2. Position the Back Module on the wall at eye level and drive the first wood screw
through the top opening (A). Position the Back Module horizontally and drive the
second wood screw through the opening (B). See Figure 1.
Note: If installing the controller on drywall or masonry, install screw anchors.
Install the lower screw anchor 73 mm directly below the top screw anchor.
Note: Conduit and adapters are not provided. Install conduit as required by local
electrical codes.
6. Remove the conduit knockout. Install 13 mm conduit (C) and (D) for 24 VAC power
wires and for valve wires.
