Calibrating Temperature Sensors

The IntelliTouch system includes two temperature sensors (10 kΩ) 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.
Getting There
MENU SETUP ADVANCED CALIBRATE
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.
