Step 3
Lay the low voltage wire in a trench 
following a path from the selected electrical 
outlet to the control box. Wires coming up 
from the ground should be run through PVC 
conduit to protect them from accidental 
damage. Be sure to bury the wire laid in the 
trench.

Low Voltage Wire from 
Transformer or Solar
Step 4
Bring enough wire up through the PVC conduit to reach the 
control board.
Step 5 
Strip 3/16” off the ends of the low voltage wire and twist 
tightly. Attach these ends to the 14VAC OR SOLAR terminals 
located on the terminal block. Be certain not to let the 
exposed wires touch each other!
Insert one transformer wire into a 14VAC OR SOLAR 
terminal. Insert the other transformer wire into the remaining 
14VAC OR SOLAR terminal. The transformer wires can be 
connected to the 14VAC OR SOLAR terminals regardless of 
color/polarity.
Tighten set screws against exposed end of wires. 
Step 6 
At the AC outlet, strip 1/2” of insulation from the ends of 
the low voltage wire. Attach these stripped ends to the 
transformer terminals. 
Make sure the exposed wires 
do not touch each other!
