w12 When room temperature is 64°F or below, the compressor cannot operate.

When room temperature rises over 64°F, the compressor starts after a 3-minute time delay. w13 Compressor ON time is decided by room temperature. Refer to page OC277-33.

w14 In dry operation, compressor ON makes the fan speed LOW and compressor OFF stops the fan. It is not possible to set the fan speed with the remote controller
