Information for multi system air conditioner (Outdoor unit: MXZ series)

Multi system air conditioner (Outdoor unit: MXZ series) can con- nect two or more indoor units to one outdoor unit. According to the capacity, two or more units can operate simultaneously.

• When you try to operate two or more indoor units with one outdoor unit simultaneously, one for the cooling and the other for heating, the opera- tion mode of the indoor unit that operates earlier is selected. The other indoor units that will start the operation later cannot operate, and will

flash the operation state. In this case, set all the indoor units to the same operation mode.

• There might be a case that the indoor unit, which is operating in (AUTO) mode. It cannot change over to the operating mode (COOL <->

HEAT) and goes to stand by mode.

• When indoor unit starts the operation while the outdoor unit is in defrost mode, it takes a few minutes (max. about 15 minutes) to blow out the

warm air.

• In heating operation, though an indoor unit that is not operating may it get warm or the sound of refrigerant flowing may be heard, it is not mal- functioning. That the refrigerant continuously flows into it.

Automatic operation

• According to a set temperature, cooling operation starts if the room tem- perature is too hot and heating operation starts if the room temperature

is too cold.

• During automatic operation, if the room temperature changes and re- mains 4 °F [2 °C] or more above the set temperature for 15 minutes, the air conditioner switches to cooling mode. If the room temperature re-

mains 4 °F [2 °C] or more below the set temperature for 15 minutes, the air conditioner switches to heating mode.

• Because the room temperature is automatically adjusted in order to maintain a fixed effective temperature, cooling operation is performed a few degrees warmer and heating operation is performed a few degrees cooler than the set room temperature once the temperature is reached (automatic energy-saving operation).

5.4. Temperature setting

To decrease the room temperature:

Press C£) button Q to set the desired temperature.

The selected temperature is displayed [].

• Each time you press the button, the temperature value decreases by 2 °F [1 °CL

To increase the room temperature: Press ¢Z3 button (_ to set the desired temperature.

The selected temperature is displayed [].

• Each time you press the button, the temperature value decreases by 2 °F [1 °CL

• Available temperature ranges are as follows:

Cooling/Drying: 67 °F [19 °C] - 86 °F [30 °C] Heating: 63 °F [17 °C] - 83 °F [28 °C]

Automatic: 67 °F [19 °C] -83 °F [28 °C]

• The display flashes either 47 °F [8 °C] - 103 °F [39 °C] to inform you if the room temperature is lower or higher than the displayed temperature.

5.5. Fan speed setting

• Press (_ '_.,d button to select a desired fan speed.

5. Operation

The display and the fan speed of the unit will differ in the following situa- tions:

• When STAND BY and DEFROST are displayed.

• Just after the heating mode (while waiting to change to another mode).

• When the temperature of the room is higher than the temperature set- ting of the unit operating in the heating mode.

• In the dry operation, the indoor fan automatically turns to low-speed operation. Switching of fan speed is impossible.

• When the temperature of the heat exchanger is low in the heating mode (e.g., immediately after heating operation starts).

Note:

• In the following cases, the actual fan speed generated by the unit will differ from the speed shown the remote controller display.

1. While the display is showing "STAND BY" or "DEFROST".

2. When the temperature of the heat exchanger is low in the heating mode.

(e.g. immediately after heating operation starts)

3. In HEAT mode, when room temperature is higher than the temperature

setting.

4. When the unit is in DRY mode.

5.6. Ventilation

For LOSSNAY combination

5.6.1. For Wired Remote-controller

• To run the ventilator together with the indoor unit:

• Press the ON/OFF button O.
