- Page 16 AH-S22DP2 AH-S25DP2 AH-S32DP2 2. DESCRIPTION OF ODOR SENSOR (1) Outline of the odor sensor The odor sensor is used to cluster display during operation. This odor sensor sensitively reacts to the various air contaminations such as a volatile organic solvent, fragrant materials and tabacco burning gas.
- Page 17 AH-S22DP2 AH-S25DP2 AH-S32DP2 What to Odor Sensor react to ? Odor Sensor also may react to vapour of insecticides, cosmetics, alcohol, hemicals and the like, and to extreme change of temperature / humidity. (2) Detection of the air contamination by the fluctuation ratio of sensor resistance The output voltage from the odor sensor is input into the microcomputer to detect the air contamination.

AH-S22DP2 AH-S25DP2 AH-S32DP2 (2) Dust detection by using the sensor The output voltage from the optical allergen sensor is input into the indoor units microcomputer to detect the air contamination (dust). This method inputs the sensor voltage per unit of time and calculates the relative fluctuation to determine whether the air is contaminated or not. -

AH-S22DP2 AH-S25DP2 AH-S32DP2 PLASMA CLUSTER OPERATION You can choose PLASMA CLUSTER AUTO OPERATION, AIR CLEAN OPERATION or REFRESHING OPERATION During operation, press the PLASMACLUSTER button to select the mode. PLASMACLUSTER AUTO AIR CLEAN REFRESHING CANCEL • In the AIR CLEAN operation, the blue PLASMACLUSTER lamp on the unit will light up. - Page 20 AH-S22DP2 AH-S25DP2 AH-S32DP2 TIP ABOUT PLASMACLUSTER OPERATION The ionizer inside the air conditioner will release cluster ions, which are collective mass of positive and negative ions, into the room. The cluster ions reduce airborne mold fungus and deodorize/decompose odor- causing molecules.
