THE “TWO-WIRE PATH”
The “two-wire path” carries the power from the controller to the valves. This
“two-wire path” is simply a two-conductor wire (Tucor #16/2) that all valves are
connected to. Valves can be connected to the two-wire path in series like a string
of ornamental lights. There is no polarity between the conductors in a two-wire
system.

Note:
“Tucor Wire” is a double-insulated, two-conductor wire made by Paige Electric specifically for Tucor.
Inside a high-density polyethylene jacket are red and black insulated conductors. These conductors are
color-coded for ease of troubleshooting.
#3
DECODERS
A “decoder” is installed at each valve solenoid and connected to the two-wire
path. The decoder acts as a switching device that turns a valve on/off with a signal
from the controller.
