• The temperature displayed on thermostat is different from thermograph.The test
methods of thermograph and thermostat are different. In general conditions,
thermostat's temperature sensor is more precise than thermograph. Due to the
difference of regions and environments thermostat has a slight deviation. If this
deviation is large (>5 °C), you can use "temperature calibration" to adjust (See
part 6.1).

6.1 Temperature calibration

Due to the regions and environments thermostat has a slight deviation. user can
adjust the temperature through "temperature calibration".
▶ Press up(P8) and down(P9) key together to enter temperature correction and
then the battery icon will flash up on the LCD.
▶ Adjust the value by "up(P8)"and "down (P9)"key. If the temperature difference is
