Installation
When choosing a location for the ET2000e Irrigation Controller, consider the accessibility of 120 VAC
power wires and the routing of the wires connected to the irrigation remote control valves. If using the
included controller box for a wall-mount or pedestal installation, a minimum of two inches of clearance
above the controller is necessary for the door to be removed after installation (Figure 1
). Additionally,
the door needs 11.5 inches on the left to fully open.
For wall mounting, be sure to mount the ET2000e Irrigation Controller on a flat, secure surface. For best
viewing, the liquid crystal display (LCD) should be at eye level of the shortest user.

Electrical
Calsense ET2000e Irrigation Controllers are electrically installed like any standard controller. The
controller is supplied with low voltage using a step-down transformer. Color-coded connector cables with
controller station wires are connected to field valve wires, while field common wires are connected to
the ET2000e Irrigation Controller commons.
