ENGLISH
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: [ CHANNEL/+ ],
[ 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 [ CHANNEL/+ ] 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 [ CHANNEL/+ ] 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.
Relative humidity
1. In normal mode, press and hold [ MODE/SET ] and [ HISTORY/− ] simultaneously
for approx. 5 seconds to enter calibration mode. Thevalue for theindoor unit’s
humidity will begin to flash.
2. Adjust thevalue to correspond with your reference value. Thevalue can be
changed in steps of 1 %.
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 these in thesame way as in point 2.
