FUNCTIONS

1. INDOOR UNIT 1-1 Temperature Adjustment

(1) Cooling

When the room temperature is higher than the preset temperature by 2˚Cor more, the unit runs at the maximum operation frequency until the temperature comes down to the preset temperature. When reaching the preset temperature, the unit runs at the frequency calculated by the fuzzy operation and switches to the normal control.

(2) Dry

After operation begins, 2 minutes of the room temperature is stored in memory, and that becomes the set value.

1-2 Indoor fan control

The fan speed can be selected from "Auto", "Soft", "Low",and "HIgh".When "Soft", "Low" or "HIgh" is selected, the fanspeed is constant regardless of the room temperature.When "Auto" is selected, the fan speed automatically changes between "Soft" and "HIgh" depending on the difference between the room and preset temperature.

Control for indoor freezing prevention

If the temperature of the indoor heat exchanger stays below approximately 1˚C for four minutes during cooling or dry, this control stops the compressor. Over 3˚C the compressor will run again.

1-3 Automatic operation

The operating mode and temperature setting are determined by the room temperature and the external air temperature.

The operating mode will changeover automatically with the following condition.

When the set temperature is adjusted within the range of ±2˚C by the remote control's key. ( ),

1-4 ON-timer

The ON-timer is set by pressing the ON-timer button. In order to attain the set temperature at the set time, the operation starting time is corrected by fuzzy computing one hour before the set time.

1-5 OFF-timer

The OFF-timer is set by pressing the OFF-timer button. Operation is as follows:

*During Cooling / Dry

1-6 Swing louvre

The louvre is moved by a stepping motor to perform swing and fixing in the set position. If the "FLOW DIRECTION" button is prossed during swing, it will stop. If the "FLOW DIRECTION" button is pressed while it is stopped, it will swing. The vertical adjustment louvre will change its angle continuously. Press the SWING button again when the vertical adjustment louvre is at the desired position.

• The louvre will stop moving within the range shown in the diagram.

• The adjusted position will be memorized and will be automatically set to the same position when operated the next time.

1-7 Restart control

Once the compressor stops, this control prevents it from starting again for 3 minutes. It also prevents starting for 80 seconds immediately following plugging into the power outlet.

1-8 One-hour operation

If this button is pressed when operation is stopped, operation will begin and then stop after 1 hour. If pressed when it is operating, will stop after one hour.

1-9 Full power operation

Immediately begins cooling or heating at maximum power and air flow.

(During cooling) Operates at setting of 18°C.

COOL and DRY modes

FAN ONLY mode

The adjustment range is narrower the SWING range in order to prevent condensation from dripping.

The range is wide so the air flow can be directed toward the floor.

1-14 Indoor/outdoor temperature display

Every time the Temperature check button is pressed on the remote control, the display changes in the order of indoor temperature outdoor temperature no display. The temperature is displayed on the temperature indicator on the main unit to be referred to for energy saving. (When the unit is not running, the display changes between indoor temperature and no display.)Indoor temperature is the temperature of the suction air measured by the room thermistor, and outdoor temperature is that measured by the outdoor temperature thermistor. When indoor temperature is displayed, the indoor LED on the main unit is lit, and when outdoor temperature is displayed, the outdoor LED is lit. For 90 seconds after the operation starts, - - is displayed instead of the actual outdoor temperature since it is still being measured.Because of the effect of the exchanger, the unit cannot confirm the exact indoor temperature right after the operation is terminated. Therefore, for one hour since the operation is stopped, the indoor temperature immediately before the operation is stopped is displayed. After over one hour since it is stopped, the unit displays the actual room temperature at that point.

1-15 Error diagnostic display

(a) Indoor unit (1) When an error is detected, all relays are

turned off. At the same time, the details of the error are displayed by flashing the number corresponding to the type of the error. The details can also be displayed by pressing down the emergency operation switch for 5 seconds or more in the state of operation stop.However, if the operation is continued only in the serial open state and the state remains unchanged after that, the main relay is turned off in 8 minutes. In the serial short state, the error is not displayed and the operation is continued. If the unit stays in the same state, the main relay is turned off in 8 minutes. Although the error is not displayed, it is memorized and can be displayed when it is recalled.

(2) If the operation is stopped and the emergency

operation button is pressed down for 5 seconds or more, the self-diagnosis memory can be recalled.

(3) Details of self-diagnosis (error mode) are

informed by the flashing number as well as the lighting pattern of the operation lamp which flashes with the timer lamp.(For details, refer to Error diagnostic method.)

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. In the figure on the right, RS indicates a sensor resistance, RL a load resistance, VRS a sensor output voltage, and VC a sensor power supply voltage. Their relation is expressed in the following formula. When the air contamination level increases, the value of the sensor resistance RS drops, which also lowers the value of the sensor output voltage.

While detecting contamination, the microcomputer outputs the following pulse to the transistor Q8, which drives the heater with the built-in odor sensor using the pulse.

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. This method detects the air contamination by converting sensor output voltage into the sensor resistance value and calculating its fluctuation ratio per unit of time. Therefore, the sensor determines that the air is contaminated when the sensor resistance value drops abruptly.

(3) Operation of the microcomputer

When the air conditioner is power on, the microcomputer starts operating and, after 1 minute, starts detecting the air contamination.

(4) Switching sensitivity of the odor sensor

The sensitivity of the odor sensor can be adjusted when the sensor is too responsive or unresponsive. It is set as standard at the factory. Sensitivity is divided into three levels: high, standard, and low. The contamination is detected when the sensor resistance drops below following percentages compared to the reference value in a clean state. (This is equal to the description of the resistance of the allergen sensor.)

3. DESCRIPTION OF THE OPTIAL ALLERGEN SENSOR (1) Outline of the optical allergen sensor

As with the odor sensor, this sensor is used to display cluster during the operation. The pulse signal is output from the microcomputer into the basic circuit show in the figure below, and the sensor signal is input into the microcomputer according to the size or amount of the dust.

(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.

(3) Operation of the indoor unit's microcomputer

As with the odor sensor, the microcomputer starts constantly detecting the air contamination level after 1 minute of the operation start.

(4) Switching sensitivity of the optical allergen sensor

The sensitivity can be adjusted. However, both sensors will be adjusted to the same level. The air contamination is detected in the following seconds at each sensor level.

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 odorcausing molecules.

AIR CLEAN OPERATION

Cluster ions released into the air will reduce airborne mold fungus and deodorize/decompose odor-causing molecules.

REFRESHING OPERATION

It is said that plenty of negative ions exist in places such as waterfalls or forests in natural environment. In this operation mode, negative inos will be released in an increased rate, in order to bring the room air close to this condition.

PLASMACLUSTER AUTO OPERATION

Dust sensor and odor sensor will detect foul air in the room. Air Clean Operation will be performed for one minute after the air conditioner is operated to detect foul air. Air Clean Operation and Refreshing Operation will be selected and be performed automatically depending on the air foul degree. Air Clean Operation will be performed when the air is detected to be foul, Refreshing Operation will be performed when the air is clean.

SELF CLEAN OPERATION

Plasmacluster Operation will be performed with FAN mode, in order to reduce the growth of mold fungus, and dry inside of the air conditioner unit. Utilize the operation at seasonal change over terms. Mold fungus already grown can not be eliminated by this operation.

2. OUTDOOR UNIT

2-1 Frequency control

(1) AC current peak control

(2) Control for prevention of outdoor heat exchanger

overheating. If the temperature of the outdoor heat exchanger exceeds the overheating prevention line 1 or 2 during cooling, the operating frequency is lowered by approximately 5 to 15 Hz. After that, the frequency is lowered by approximately 5Hz once every 60 seconds or approximately 15Hz once every 120 seconds. When the temperature of the outdoor heat exchanger goes below the overheating prevention clear line, the frequency is raised by approximately 5 Hz once every 60 seconds, and normal operation is restored. If the frequency is lowered to minimum frequency without the temperature of the outdoor heat exchanger decreasing and this condition lasts for 1 minute, the compressor will be stopped.

(3) Control for prevention of discharge overheating

If the discharge temperature exceeds approximately 105°C during compressor operation, the operating frequency is lowered by approximately 5 Hz. After that, the frequency is lowered by approximately 5 Hz once every 60 seconds. When the discharge temperature goes below approximately 104°C , the frequency is raised by approximately 5 Hz once every 60 seconds, and normal operation is restored. If the frequency is lowered to minimum frequencywithout the discharge temperature decreasing and this condition lasts for 1 minute, the compressor will be stopped.

(4) Control for prevention of indoor heat exchanger

freezing If the temperature of the indoor heat exchanger goes below approximately 5°C during cooling(only Full power operation), the operating frequency is lowered by approximately 5 Hz. After that, the frequency is lowered by approximately 5 Hz once every 60 seconds. When the temperature of the indoor heat exchanger rises above approximately 5°C, the frequency is raised by approximately 5 Hz once every 60 seconds, and normal operation is restored. If the temperature of the indoor heat exchanger goes down to approximately 0°C and this condition continues for 4 minutes, the compressor is stopped. When the temperature rises above approximately 2˚C, normal operation is restored.

2-2 Overcurrent protection

(1) Compressor lock detection

If the set value 2.7A of AC current is exceeded in 6

seconds when operation begins, operation is stopped. In this case, the outdoor fan does not stop, and 170 seconds after operation is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minute delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power.

(2) DC overcurrent detection, AC overcurrent detection

To protect against overcurrent due to sudden changes in load, the compressor is stopped if the set value (AU-S32DP2: 47A, AU-S22DP2/S25DP2: 26A) DC is exceeded in the DC section, or the set value (AUS22DP2/S25DP2: 11A, AU-S32DP2: 13A) AC is exceeded in the AC section. In this case, the outdoor fan does not stop, and 170 seconds after operation is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minute delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power.

2-3 Compressor protector control

If the temperature of the compressor chamber exceeds 114°C, the compressor is stopped. In this case, the outdoor fan does not stop, and when the compressor chamber temperature decreases to 100°C three minutes after operation is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minute delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power.

2-4 Power transistor module protector

If the temperature of the chips in the power transistor module exceeds 105 °C, the compressor is stopped. In this case, the outdoor fan does not stop, and when the temperature of the chips in the power transistor module decreases to 105 °C and 170 seconds seconds after operation is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minute delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power.

2-5 Serial signals

(1) Serial signals consist of all 96-bit signals. (2) If the outdoor unit does not receive a serial signal, it

will stop approximately 30 seconds later. Note that this is true only of normal operation; in test mode, it does not stop and operation takes place based on the test mode commands.
