Calibration of Temperature or Relative Humidity
The TrueTouch™ Thermostat is rated for an accuracy of +/-1°F (+/-0.5°C) with temperature
and +/- 5% for Relative Humidity.
If you have determined due to drafts, sunlight or other environmental factors that your ther-
mostat requires calibration, follow this easy guide. Common cause of offset are lack of air
circulation, drafts or skylights in the direct vicinity of the thermostat.
Measure humidity with a conventional hygrometer or any other device that provides a
accurate reading. Then compare to the reading on your TrueTouch™ thermostat and
calibrate by up to +/- 15 degrees.
