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 OC276-30.

w14 In dry operation, compressor ON makes the fan speed LOW. Also, when the compressor OFF and the pipe temperature is 79°F or less, the fan stops, or when the compressor OFF and the pipe temperature is below 43°F the fan speed changes to LOW mode.

It is not possible to set the fan speed with the remote controller
