Electrical Installation
Installing and Connecting Temperature Sensors
Water Temperature Sensor
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 8mm diameter hole in one side of the pipe,
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 over-tighten
3. Run the two-conductor cable (included in kit) between the sensor and the Personality board.
Route the wire up through the Load Centre low voltage raceway to the Personality board.
4. Fasten the cable to the plumbing with cable ties.
5. Insert the wires into the WATER SENSOR screw terminals (J21) on right-side of the mother-
board. For motherboard connection details, refer to “EasyTouch Motherboard Connections,” on
page 14. For wiring details, refer to EasyTouch System Wiring Diagram,” on page 20.
Ambient Air Temperature Sensor (for freeze protection)
To install the air sensor:
1. Mount the sensor in the open air, in a shaded area, away from air conditioners. During the win-
ter months, to avoid freeze damage to pool and spa equipment, mount the air sensor in a shad-
ed area to assure proper temperature readings. The main screen displays the current ambient
air temperature.
2. Route the wire through the low voltage raceway to the motherboard.
3. Fasten the cable to the plumbing with cable ties.
4. 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) or any sunny location. 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 Load Centre. Use waterproof connectors to connect the sensor to
the cable. Use 2-core 1mm
2
outdoor rated sensor wiring and be sure the wire connections are
protected from the environment. Use shielded cable for long runs or runs near other electrical
wiring.
3. Insert the wires into the SOLAR SENSOR screw terminals (J21) on right side of the mother-
board.
