Installation Guide
COMMERCIAL WIRELESS SMART CONTROLLER (MODEL 105/205 Gen 4)
Step 1: Turn off power and remove existing controller
Turn off the circuit breaker supplying power to the installation site. If you have an old
controller already in place, disconnect it from the power source, and label the valve wires.
Then disconnect the valve wires and remove the old unit from the mounting surface.
Step 2: Mount ET Water smart controller
Slide the front cover off its hinges. Remove the lower panel first (2 screws), then remove the four
screws that anchor the upper panel. Remove the upper panel, being careful not to pull on the
ribbon and antenna cables that
are attached to the back. Nestle
the panel into the bottom of
the controller such that it re-
mains in place while you attach
the controller to the mounting
surface using the screws and
washers provided. Position the
black rubber washer between the mounting surface and the back of the controller. Position the
small plastic washer inside the controller.
Your wireless ET Water Smart Controller uses cellular service to communicate with the ET Water
servers. There are two types of antennas available: high gain or a vandal-proof, dome style
pancake. IMPORTANT: Installation inside metal enclosures, electrical closets, or subterranean
rooms will likely result in poor or insufficient cell signal strength. If you would like to have your
site pre-tested for antenna compatibility, or if you are unable to connect to the ET Water server
(see Step 8), please call customer support.
