A: Sensor Installation
IMPORTANT: Turn off all power at the circuit breakers. If the equipment is below
the pool, turn off any valves to prevent pool water from draining.
For water temperature sensor:
1Loosen the clamp and remove the old Water Temperature Sensor. (For a new
installation Drill a 3/8” hole in the pipe between the filter pump and the filter.).
2Ensure the o-ring on the sensor and insert the sensor into the pipe.
3Tighten the pipe clamp around the sensor. Be sure the wire is not under the pipe clamp
or pinched.
For air temperature sensor:
1Install the Air Temperature Sensor in a convenient location exposed to shaded outdoor
air temperatures.
2DO NOT place the sensor in direct sunlight.
For solar temperature sensor:
1Install the Solar Temperature Sensor next to the solar panels.
2DO NOT place the sensor in the pipe or in direct sunlight.
B: Sensor Wiring
1Run the sensor wire to the AquaLink RS Power Center. Be sure to run the wire in the
low voltage raceway (See wiring diagram on Power Center door).
2Remove the green 10-pin terminal bar from the Power Center Board.
3Connect the temperature sensor wires to the green 10-pin terminal bar in the positions
indicated on the wiring diagram located on the door of the Power Center.
4Replace the green 10-pin terminal bar on the Power Center Board.
5Restore power to the system and check for normal system operation.
IMPORTANT: Determine the length the sensor wire needs to be. Cut the end of the wire off,
DO NOT splice this wire.
