Connect Main Power Wires
ESP-LX+ (Outdoor / Indoor Controller)
NOTE: To connect main power wires on the
ESP-LXi+ indoor-only controller, see the instructions
on page60.
The ESP-LX+ controller has an internal transformer that
reduces standard supply voltage (117 VAC in U.S. models;
230 VAC in international models) to 24 VAC to operate the
valves connected to the controller. You will need to connect
power supply wires to the transformers three wires.
➊ With the door and face panel removed, locate the high-
voltage compartment in the lower left corner of the controller
cabinet.
➋ Remove the screw on the right edge of the compartment
cover. Then swing the cover open to expose the
transformers primary input wires.
