7-5. Removing and Installing the Grille Basically, these models can be installed and wired without removing the grille. If access to any internal part is need- ed, follow the steps as given below. How to remove the grille Open the front panel until it is nearly horizontal, grasp the sections near the front panel arms on both sides, and then remove the panel by pushing the arms towards the outside while pulling the panel towards you.
Page 46: Functions
8. FUNCTIONS 8-1. Room Temperature Control (1) Cooling Room temperature control is obtained by cycling the compressor ON and OFF under control of the room temperature sensor in the indoor unit. NOTE Some informations except for the room temperature are transmitted every 5 minutes by the remote control unit to the controller in the indoor unit.
Page 47 (2) Heating Room temperature control is obtained by cycling the compressor ON and OFF under control of the room temperature sensor in the remote control unit. The room temperature (and other information) is transmitted every 5 minutes by the remote control unit to the controller in the indoor unit.
Page 48: Dry Operation (Dehumidification)
8-2. Dry Operation (Dehumidification) Dry operation uses the ability of the cooling cycle to remove moisture from the air, but by running at low level to dehumidify without greatly reducing the room temperature. The air conditioner repeats the cycle of turning ON and OFF automatically as shown in the chart below according to the room temperature.

8-3. Automatic Switching between Cooling and Heating When AUTO mode is selected, the microprocessor calculates the difference between the set temperature and the room temperature, and automatically switches to COOLING or HEATING mode to maintain the desired temperature. Room temp. Set temp.
Page 50: Freeze Prevention (Cooling And Dry)
8-4. Freeze Prevention (Cooling and Dry) This function prevents freezing of the indoor heat exchange coil. When the temperature of the indoor heat exchange coil falls below 2 C for 2 minutes, the control circuit stops the outdoor fan and compressor (The compressor stops 3 seconds after the outdoor fan stopped). During this period, Indoor fan operates in LL.

Page 52: Cold Draft Prevention (Heating)
8-6. Cold Draft Prevention (Heating) This function controls indoor fan speed so a strong draft of cold air will not blow out before the indoor heat exchange coil have sufficiently warmed up. Indoor fan speed varies according to the indoor heat exchange coil temperature as table shown below. Condition Indoor coil temperature ( C) Indoor fan speed...
Page 53: Overload Prevention (Heating)
8-7. Overload Prevention (Heating) This function prevents overheating of the indoor heat exchange coil. When the temperature of the indoor heat exchange coil rises above T2 C, the outdoor fan stops, if the indoor fan is L (low speed), then the fan speed changes from L (low speed) to M (medium speed). When the temperature of the indoor heat exchange coil rises above T1 C, the compressor stops, and indoor fan runs in LL (very low speed).

7-5. Removing and Installing the Grille Basically, these models can be installed and wired without removing the grille. If access to any internal part is need- ed, follow the steps as given below. How to remove the grille Open the front panel until it is nearly horizontal, grasp the sections near the front panel arms on both sides, and then remove the panel by pushing the arms towards the outside while pulling the panel towards you.
Page 127: Functions
8. FUNCTIONS 8-1. Room Temperature Control (1) Cooling Room temperature control is obtained by cycling the compressor ON and OFF under control of the room temperature sensor in the indoor unit. Some informations except for the room temperature are transmitted every 5 minutes NOTE by the remote control unit to the controller in the indoor unit.
Page 128 (2) Heating Room temperature control is obtained by cycling the compressor ON and OFF under control of the room temperature sensor in the remote control unit. The room temperature (and other information) is transmitted every 5 minutes by the remote control unit to the controller in the indoor unit.
Page 129: Dry Operation (Dehumidification)
8-2. Dry Operation (Dehumidification) Dry operation uses the ability of the cooling cycle to remove moisture from the air, but by running at low level to dehumidify without greatly reducing the room temperature. The air conditioner repeats the cycle of turning ON and OFF automatically as shown in the chart below according to the room temperature.
Page 130: Automatic Switching Between Cooling And Heating
8-3. Automatic Switching between Cooling and Heating When AUTO mode is selected, the microprocessor calculates the difference between the set temperature and the room temperature, and automatically switches to COOLING or HEATING mode to maintain the desired temperature. Room temp. Set temp.
Page 131: Freeze Prevention (Cooling And Dry)
8-4. Freeze Prevention (Cooling and Dry) This function prevents freezing of the indoor heat exchange coil. When the temperature of the indoor heat exchange coil falls below 2 C for 2 minutes, the control circuit stops the outdoor fan and compressor (The compressor stops 3 seconds after the outdoor fan stopped). During this period, Indoor fan operates in LL.

Page 133: Cold Draft Prevention (Heating)
8-6. Cold Draft Prevention (Heating) This function controls indoor fan speed so a strong draft of cold air will not blow out before the indoor heat exchange coil have sufficiently warmed up. Indoor fan speed varies according to the indoor heat exchange coil temperature as table shown below. Condition Indoor coil temperature ( C) Indoor fan speed...
Page 134: Overload Prevention (Heating)
8-7. Overload Prevention (Heating) This function prevents overheating of the indoor heat exchange coil. When the temperature of the indoor heat exchange coil rises above T2 C, the outdoor fan stops, if the indoor fan is L (low speed), then the fan speed changes from L (low speed) to M (medium speed). When the temperature of the indoor heat exchange coil rises above T1 C, the compressor stops, and indoor fan runs in LL (very low speed).
