Calibrating Temperature Sensors
The IntelliTouch system includes two temperature sensors (10 k
Ω
) for water and ambient air
temperature. You can add a third sensor for controlling solar heating systems. Note: The i10+3D system
includes three sensors.
Generally, these sensors are accurate and you do not have to calibrate them. However, long plumbing
runs and water features cause temperatures at a body of water to be different from the temperature
sensor reading. You can manually recalibrate the sensors to adjust for this.
Before you start, you need an accurate all weather thermometer. If you are calibrating the air sensor,
wait until the sensor is not in direct sunlight. Be sure that the air sensors are located in the shade for
accurate freeze protection.
To calibrate the water and air sensors, go to the
Calibrate
screen.
For i10+3D systems, you will see
Spa Temp
,
Pool Temp
, and
Air Temp
. Calibrate the spa and pool
water temperatures the same way as described below for the water sensor. If you have an i5+3, i5S+3,
i7+3, or i9+3 system, there is a water sensor and an air sensor. Make sure to locate the air sensor in the
shade for accurate readings. Make sure to locate the solar sensor in the sun for accurate readings.
To calibrate the water sensor:
1. Switch on the spa or pool filter pump.
2. Place the thermometer in the spa or pool, depending on the system model number. For shared
equipment, you only need to calibrate one body of water.
3. Take an accurate temperature reading.
4. At the Indoor Control Panel, press the buttons next to the
Water Temp
label to adjust the temperature
up or down. If you have an i10+3D repeat the above for the pool. The i10+3D has three sensors, one
each for the spa and pool water and one for the air temperature. For the Solar option there will be one
sensor for the pool solar, and one for the spa solar.
5. Press the
Exit
button when finished.
To calibrate the air sensor:
1. Place the thermometer next to the air sensor. The sensor is normally located near or under the Load
Center or Power Center enclosure, not inside the enclosure.
2. Take an accurate temperature reading in the shade.
3. At the Indoor Control Panel, press the buttons next to the
Air Temp
label to adjust the temperature up
or down.
4. Press the
Exit
button when finished.
