Installing and Connecting Temperature Sensors
Water Temperature Sensor
To install the water sensor:
1. Drill a 5/16 in. hole in the plumbing between the filter pump and filter.
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
3. At the EasyTouch load center, route the wire up through the low voltage raceway to the
motherboard.
4. Fasten the cable to the plumbing with cable ties.
5. Cut off the excess wire and the strip conductors ¼ inch. Insert the wires into the WATER
screw terminals (J21) on right-side of the motherboard. For motherboard connection details,
refer to “EasyTouch Motherboard Connections,” on page 13. For wiring details, refer to
EasyTouch System Wiring Diagram,” on page 23.
Ambient Air Temperature (Freeze Protection) Sensor
To install the air sensor:
1 Mount the sensor in the open air, in a shaded area, away from air conditioners. During the
winter months, to avoid freeze damage to pool and spa equipment, mount the air sensor in a
shaded area to assure proper temperature readings.
2 Route the wire through the low voltage raceway to the motherboard.
3 Fasten the cable to the plumbing with cable ties.
4 Cut off the excess wire and the strip conductors ¼ in. Insert the wires into the AIR screw
terminals (J21) on right side of the motherboard.
Solar Temperature Sensor (Optional)
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.
2 If necessary, splice a two-conductor extension wire to the sensor. Route the wire to the load
center and up through the low voltage raceway to the motherboard.
3 Strip the conductors ¼ in. Insert the wires into the SOLAR screw terminals (J21) on right
side of the motherboard.
