Snooze
• When the alarm sounds, press [ SNOOZE/LIGHT ] to temporarily silence the alarm
for 5 minutes. The alarm symbol will continue to flash.
• To permanently silence the alarm, press one of the other buttons: [ C ],
[ MODE/SET ], [ MAX/MIN/ALARM ] or [ HISTORY/− ].
Calibration
• If the connected sensors display inaccurate values, they can be recalibrated.
To calibrate the sensors properly, you must have reference values from meters/
sensors that you know give accurate readings.
• The calibrated value can only be displayed on the indoor unit. The external
thermometers/hygrometers always show the uncalibrated value.
• The range for relative humidity is always between 10 and 99 %. It is not possible to
adjust the value beyond this range.
• Press [ C ] or [ HISTORY/− ] to increase or decrease the selected value.
To change the value more quickly, press and hold the button for 3 seconds.
• Press [ MAX/MIN/ALARM ] to reset the adjusted value.
• To complete the calibration and return to the normal display mode, press
[ SNOOZE/LIGHT ] or wait for 30 seconds.
Temperature
1. In normal mode, press and hold [ MODE/SET ] and [ C ] simultaneously
for approx. 5 seconds to enter calibration mode. The value for the indoor unit’s
temperature will begin to flash.
2. Adjust the value to correspond with your reference value. The value can be
changed in steps of 0.1 °C.
3. Press [ MODE/SET ] to calibrate the external sensor’s value.
4. If you have several external sensors connected, press [ MODE/SET ]
repeatedly to scroll through the channels (1–8) and adjust in the same way as in
point 2.
