MODE Notes on each operation mode Since this air conditioner heats the room by taking heat from outdoor air to indoors, the heating capacity becomes smaller in lower outdoor temperatures. If the heating effect is insufcient, it is recommended to use another heating appliance in combination with the air conditioner. The heat pump system heats the room by circulating hot air around all parts of the room. After the start of HEAT operation, it takes some time before the room gets warmer. In HEAT operation, frost may occur on the outdoor unit and lower the heating capacity. In that case, the system switches into defrosting operation to take away the frost. During defrosting operation, hot air does not ow out of indoor unit. This air conditioner cools the room by blowing the hot air in the room outside, so if the outside temperature is high, the performance of the air conditioner drops. The computer chip works to rid the room of humidity while maintaining the temperature as much as possible. It automatically controls temperature and airow rate, so manual adjustment of these functions is unavailable. In AUTO operation, the system selects a temperature setting and an appropriate operation mode (COOL or HEAT) based on the room temperature at the start of the operation. The system automatically reselects setting at a regular interval to bring the room temperature to user-setting level. This mode is valid for fan only.

Tips for saving energy

Be careful not to cool (heat) the room too much. Keeping the temperature setting at a moderate level helps save energy. Cover windows with a blind or a curtain. Blocking sunlight and air from outdoors increases the cooling (heating) effect. Clogged air lters cause inefcient operation and waste energy. Clean them once in about every 2 weeks.
Notes on the operating conditions
The outdoor unit consumes some power to have its electric components work even while it is not operating. Connecting outdoor unit RXG25/35: 1-15W Other outdoor units: 15-20W The outdoor unit consumes 40 to 55W of power at the time of compressor preheating. If you are not going to use the air conditioner for a long period, for example in spring or autumn, turn the breaker off. Use the air conditioner in the following conditions. MODE COOL Operating conditions Outdoor temperature : <2/3/4/5MXS> 10-46C <RXG> 10-46C Indoor temperature : 18-32C Indoor humidity : 80% max. Outdoor temperature : <2MXS> 10-24C <3/4/5MXS> 15-24C <RXG> 15-24C Indoor temperature : 10-30C Outdoor temperature : <2/3/4/5MXS> 10-46C <RXG> 10-46C Indoor temperature : 18-32C Indoor humidity : 80% max. If operation is continued out of this range A safety device may work to stop the operation. (In multi system, it may work to stop the operation of the outdoor unit only.) Condensation may occur on the indoor unit and drip. A safety device may work to stop the operation.
