Electronic Controller*
Step 1:
Mount controller to vertical surface. This should be a rigid structure or wall.
Step 2:
Remove the 6 Phillips head screws around the perimeter of the front panel.
Carefully lift the front panel making sure to not pull on the attached wire harness.
If possible, support front cover without letting it hang from the wires and move onto
step 3
. If the front
cover cannot be supported, then it can be removed completely by removing the white connector (RD500
-0 only) and the red spade connectors on the cover.
Step 3:
Install the solenoid wires through the sealed plug/nut on the bottom of the box. You will need about 6 inches
of wire passed through the box. This nut may need to be loosened to pass the wires through.
Step 4:
Remove the green connector.
Step 5:
Strip approximately ¼ inch of jacket from each solenoid wire.
Step 6:
Begin installing hot leads on solenoids beginning with #1. (2), (4), (6), or (8) zones.
Step 7:
Using a sealed wire nut, combine all of the solenoid common wires together with a common wire in the cable
bundle (typically white). This will connect to the “C” (common) input on the green connector.
Step 8: (RD500-0 ONLY)
For a fresh water system (or rain diverter valve) you can connect the additional solenoid to an “H” (hot) and
“C” (common) input.
Step 9:
Route and plug in the green connector. Ensure that the solenoid wires are not making contact with the circuit
board.
Step 10:
Fasten the sealed plug/nut so that it creates a seal and clamps onto the solenoid wires.
Step 11:
Re-install the front cover and electrical connections.
Step 12:
Leaving the power off to the controller, plug the controller into a GFCI protected outlet or Rain Deck timer
box.
(RD550-1).
