Installing Aqua-Sensor
1. Locate the Aqua-Sensor 2.5VAC power cord and bushing (01025264) packed in the small parts pack. The
power cord has two spade terminals on one end of the cable and a plastic female connector on the other end.
2. Disconnect power from the circuit board.
3. Remove the power cord bushing (P/N 01025274) from the outdoor enclosure (location #1 in Figure 21) by loos-
ening the nut from the 24V power cord bushing.
4. Discard the dummy connector on the 2.5VAC circuit board
pins.
5. Remove the bushing cable assembly from the enclosure.
6. Press a small screwdriver into the slots on the plastic female
connector housing to remove the two metal slip-in tabs on
the 24V power cord. See Figure 24.
7. Remove the 01025274 bushing from the 24V power cord.
8. Insert the 24V and 2.5VAC power cords through the shared
bushing (P/N 01025264). See Figure 25.
9. Use a small screwdriver to raise the tongue on each metal
tab so it is protruding at the top. Reinstall the tabs in the
housing. Tug lightly on the cord to make sure the tab does
not pull free from the housing. See Figure 24.
Figure 25. 24V Power and Aqua-Sensor connections on the controller.
10. Reinstall the terminal plugs on the 24V plastic connector.
11. Place the bushing with the cable through the opening and tighten the nut that is on the interior of the enclosure.
12. Plug each power connector to the appropriate pin on the Smart Controller circuit board. See Figure 26.
CAUTION! Verify wiring from the terminals to circuit board are correct before applying power to
the control. 24V power must not be applied to the 2.5 VAC terminals. Connecting 24V
to the 2.5 VAC connection on the circuit board will damage the circuit board.
