Centigrade), on a circuit controlled by a
switch, or on the same circuit as a high power
user (refrigerator air conditioner garage door
opener. etc.). Ma/functions may result.
A. Run valve wiring underground wherever possible.
For line runs less than 800 feet long, use 18-gauge,
plastic jacketed thermostat control wire; over 800 feet,
use 14-gauge wire. Your dealer can provide this wire in
2.3.4.5.6.7 and 8-wire color-coded strands.
8. Connect a single common wire to one of the wires
from each valve.
C. Solder or join all splices with wire nuts; then seal
with vinyl or waterproof cement to assure a water-
resistant connection.

using two screws.
B. Position controller over mounting bracket engaging
tabs into recessed slats in back of controller housing.
To lock in place, pull down on controller until tabs reach
