2. AUTO CHANGEOVER OPERATION
When the air conditioner is set to the AUTO mode by remote control, operation starts in the optimum
mode from among the HEATING, COOLING, DRY and MONITORING modes. During operation, the
optimum mode is automatically switched in accordance with temperature changes. The temperature
can be set between 64°F(18°C) and 88°F(30°C) in 2°F(1°C) steps.
.When operation starts, only the indoor and outdoor fans are operated for 1 minute. After 1 minute,
the room temperature and outside air temperature are sensed and the operation mode is
selected in accordance with the table below.
