Advanced Menu (8/14): Calibrate Water, Air and Solar Sensors
The SunTouch
®
Control System includes two temperature sensors for monitoring water and ambient air
temperature. An additional air sensor for controlling solar heating systems can also be installed for solar
systems. Generally, these sensors are accurate and do not require calibration. However, long plumbing runs
and water features can 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. You only need to calibrate one body of
water, since the temperature sensor is common to both the pool and spa.
CALIBRATION
Before you start, you’ll need an accurate all weather thermometer. When calibrating the air sensor, wait until
the sensor is not in direct sunlight. For the air temperature sensor, make sure that the sensor is located in the
shade for accurate readings.
To calibrate the water temperature sensor:
Menu button:
Select the
Advanced 8/14
menu.
Right button:
Press the button until
Calibrate Water
is displayed.
Up/Down buttons:
To adjust the temperature use these buttons to raise or lower the
water temperature to match the corresponding thermometer temperature reading.
When calibrating the water sensor, first switch off the heater. Check that the “Pool”
filter pump circuit is set to “ON” to switch on the pool filter pump or press the Spa
button (
Up button
) to circulate the water. Place the thermometer in the spa or pool
water. Take an accurate temperature reading.
Right button:
Select
Calibrate Air
.
Up/Down buttons:
To adjust the temperature use these buttons to raise or lower the
water temperature to match the corresponding thermometer temperature reading.
When calibrating the air sensor, place the thermometer next to the air sensor. The air
sensor is normally located near or under the SunTouch Control System enclosure, not
inside the enclosure. Take an accurate temperature reading in the shade.
Right button:
Select
Calibrate Solar
.
Up/Down buttons:
To adjust the solar temperature use these buttons to raise or lower
the water temperature to match the corresponding thermometer temperature reading.
Be sure that the solar sensor is in the sun for accurate readings.
