2. Connect the Controller
The controller must be connected to your sprinkler valves. If you have an existing sprinkler controller, the sprinkler valves are connected to the
controller with the wires typically inserted into numbered slots, which are called zones. Often these wires are in multiple colors. Before disconnecting an
existing controller, make note of which wire runs to each sprinkler valve and mark them accordingly.
There should be a single wire for each zone plus a common wire. The common wire is generally the white wire. (If you are replacing an existing sprinkler
controller note the wire marked “common” or “ground”.) Make sure that each valve wire has at least ½” of wire exposed
on the end which will be connected to the Cyber-Rain controller.
Connect the common wire to the left most opening in the valve wiring harness (make sure the screw terminals are
facing up). Wires are connected by inserting the wire into the corresponding socket from the bottom of the harness and
using a 1/8” slotted screwdriver to tighten the wire at the appropriate terminal location.
Next, connect the sprinkler valve wires and tighten for each zone starting from left to right starting with zone 1 and
going through zone 8. Make sure to note a description of each zone and the slot that you are connecting it to on the
chart below. If your sprinkler system has fewer than 8 zones, start with zone 1 and continue until finished. All 8 zones do
not need to be activated. If you have more zones than outputs available on your controller (either 8, 16 or 24 depending
on your controller model), you will need an additional controller (see section on Adding Additional Controllers). Insert
the valve wiring harness into the connector located on the bottom of your controller labeled “C 1 2 3 4 5 6 7 8 M”
making sure that it is properly aligned with the two alignment slots.
If you have a 16 or 24 zone XCI controller, it will include additional wire harnesses. These wire harnesses have 9 ports instead of 10. If you have
additional common lines, connect the commons to the leftmost slots of the additional harnesses. Continue inserting valve wires from left to right
starting with zone 9. Then insert the valve wire harness into the unused connector closest to the 10 pin connector.
