4. The individual at the controller should double-check that you are calibrating the correct sensor.
You might warm/cool the sensor temporarily to see which sensor changes temperature
appropriately.
5. Once you determine the correct temperature and allow approximately one minute for
stabilization in the water, adjust the sensor reading at the controller.
6. Offset the factor using the left/right arrow keys.

9.3 CO2 Sensor
To calibrate the CO2 level, obtain a suitable test kit and use the procedures described in the kit. Ensure
that the house is well ventilated, either naturally or using fans.
CAUTION
Only calibrate the sensors if you have reason to believe that they are producing
inaccurate results.
