Section 5. Low Voltage Wiring
All low voltage wiring should be run through the knockouts in the low
voltage compartment (right side of controller enclosure). See Figure 4.
IMPORTANT
Never run high voltage and low voltage in the same conduit.
3. Feed the sensor wire through the black low voltage wiring
knockout.
4. Strip 1/4” of insulation and separate the wires.
5. Connect sensor wires to pins #5 and #6 of the 10-pin blue
connector.

Install the Water Temperature
Sensor
1. Drill a hole for mounting the water temperature sensor line
in the pipe between the pump and the filter (before the
heater).
2. Install the O-ring on the sensor and insert the sensor into
the hole. Wrap and tighten metal clamp around the pipe to
secure sensor.
5.1
Wire the Temperature Sensors
Wire the temperature sensors on the 10-pin blue connector (see
Figure 10.4 Wiring Diagram). The air temperature sensor is factory-
installed on the 10-pin blue connector (#7 & #8). The water
temperature sensor and necessary installation hardware is included.
