● OPERATING INSTRUCTIONS ●

AUTO mode (Auto changeover)

The unit selects the operation mode according to the difference between the

room temperature and the set temperature. During AUTO mode, the unit

changes mode (COOL↔HEAT) when the room temperature is 2°C away

from the set temperature for more than 15 minutes.

Note:

During multi system operation, the unit may not be able to switch opera-

tion mode between COOL and HEAT. In this case, the indoor unit be-

comes standby mode.

Do not operate COOL mode at low outside temperature (less than -10°C).

Water condensed in the unit may drip and wet or damage furniture, etc.

If a power failure occurs or the main power is turned off during operation, “Auto

Two or more indoor units can be operated by one outdoor unit. When several

indoor units are operated simultaneously, cooling and heating operations can-
