Installing and Connecting Temperature Sensors

Water Temperature Sensor (P/N 520272)
To install the water sensor:
1. Select a convenient location to mount the water sensor in the plumbing
system between the filter pump and filter. Drill a 3/8" diameter hole in one
side of the pipe. If solar override is necessary, install sensor underneath
the pipe. This will help ensure a more accurate reading of the stagnate
water in the pipe if sensor is in direct sunlight.
2. Insert tip of sensor into the hole. Use the band clamp to secure the
sensor to the pipe. Tighten the clamp just enough so that the o-ring
begins to flatten. Do not overtighten. Fasten the cable to the plumbing
with cable ties.
3. Run 22-gauge two-conductor cable (included) between the sensor circuit
board. Route the wire up through the grommet on the bottom of the
enclosure to the SolarTouch
4. At the SolarTouch controller enclosure, cut off the excess wire and
the strip conductors ¼ inch. Insert the sensor wires into the WATER
SENSOR screw terminals (JP1 Pool) on right-side of the SolarTouch
controller circuit board (see page 18). Note: There are three screw
terminals; use the middle screw terminal to share with one of the solar
sensor wires. No polarity is required with the sensors.
Solar Temperature Sensor (P/N 522101)
Run a two-conductor cable between the sensor and the controller. The maximum sensor
cable length is 300 ft (90 m) from the controller enclosure.
To install the solar sensor:
1. Mount the sensor on a flat surface, with the same exposure to sun as
the solar collectors (next to the collectors is recommended). Do not let
the sensor touch the panels. WARNING: DO NOT DRILL HOLE AND
CLAMP SENSOR INTO SOLAR PIPE. For glazed panels, install the
sensor between collector and glazing.
2 If necessary, splice a two-conductor extension wire to the sensor. Run
two-conductor cable between the sensor and the controller enclosure.
Use waterproof connectors to connect the sensor to the cable. Use
twisted pair 20 AWG outdoor rated sensor wiring and be sure the wire
connections are protected from the environment. Use shielded cable for
long runs (300 ft. - 90 m) total wire length maximum) or runs near other
electrical wiring.
3. Run 22-gauge two-conductor cable (included) between the sensor circuit
board. Route the wire up through the grommet on the bottom of the
enclosure to the SolarTouch controller circuit board (see page 18).
4. At the SolarTouch controller enclosure, cut off the excess wire and
the strip conductors ¼ inch. Insert the sensor wires into the SOLAR
SENSOR screw terminals (JP1 Solar) on right-side of the SolarTouch
controller circuit board (see page 18). Note: There are three screw
terminals; use the middle screw terminal to share with one of the water
sensor wires.
