- press the SET key to accept the changes and advance to the next display mode. Continue to press the
SET key to toggle through the display mode until you return to the normal Mode
5.2 Setting Modes
Press the SET key for 3 second while in normal mode to enter the normal Setting mode
Press the SET key to select the following setting in sequence :
-
1) Time Zone Setting (should be set at "-1" for UK and "0" For Germany)
2) 12/24 hour format
3) Manual time setting (hours/minutes)
4) Calendar setting (year /month /date)
5) Temperature display unit degree Celsius or Fahrenheit
6) Indoor humidity calibration
7) Outdoor humidity calibration
8) Air pressure display units in hPa or inHg
9) Relative pressure setting from 919.0hPa – 1080.0hPa (default 1013.5hPa)
10) Pressure threshold setting (default 2hPa)
11) Storm threshold setting (default 4hPa)
- In the setting modes, press + key or MIN/MAX key to change or scroll the value. Hold the +key or
MIN/MAX key for 3 second will increase/decrease digits in greater steps.
Press SNOOZE/LIGHT key or no key for 10 seconds and the setting mode will revert to Normal

Note: Please first set the units of measurement before attempting to change unit values. During change
of units setting, units' value will change according to new units but it might cause resolution loss due to its
internal calculation algorithm.

5.2.1 Setting Calibrated Humidity

The display console allows you to calibrate both the indoor and outdoor humidity. Humidity is a difficult
parameter to measure accurately and drifts over time. The calibration feature allows you to zero out this
error. To calibrate humidity, you will need an accurate source, such as a hygrometer.
To calibrate indoor humidity, in the Set Mode with indoor humidity flashing, press the + key or MIN/MAX
key to increase or decrease the humidity setting (in increments of 1%) to match the calibrated or known
humidity source. To return the indoor humidity to the measured value, press and hold the SET key for 3
seconds and the humidity will return to the uncalibrated value.
To calibrate outdoor humidity, in the Set Mode with outdoor humidity flashing, press the + key or
MIN/MAX key to increase or decrease the humidity setting (in increments of 1%) to match the calibrated
or known humidity source. To return the outdoor humidity to the measured value, press and hold the SET
key for 3 seconds and the humidity will return to the uncalibrated value.
Note: The remote (outdoor) thermo-hygrometer will always display the measured humidity level and not
the calibrated humidity level. Only the console will show the calibrated value.
Note: The dew point calculation is based on the calibrated humidity level.

5.2.2 Setting Barometric Pressure

The display console displays two different pressures: absolute (measured) and relative (corrected to
sea-level).
