Option B Installation
1. Use an existing opening or drill an opening through
the outside wall for 1/2-inch (13 mm) rigid conduit.
The sensor must be located three to six inches
(7.5 to 15 cm) from the wall.
2. Remove the pulling elbow cover and gasket.
3. Pull the sensor lead wires from the pulling elbow
and thread the pulling elbow/sensor assembly onto
the conduit as shown in Figure 2.
4. Rotate the sensor so that the shield points down
and shades the sensing element from direct and
indirect sunlight.
5. Cut off the excess sensor wire leads approximately
one inch (25 mm) from the pulling elbow and strip
3/8-inch (9.5 mm) of insulation from the ends of the
leads.
6. Pull the field wiring to the pulling elbow.
7. Connect the field wiring to the sensor wiring as
shown in Figure 2.
8. Replace the pulling elbow cover and gasket. Ensure
that the gasket seals the pulling elbow.
9. Connect the field wiring at the controller as shown
in the wiring diagram. See Figure 3.
The installation is now complete.
