Notes:
(1) The product determines the room temperature category and external temperature category as shown in Tables 1, 2, and 3 according to the room temperature and
external temperature, and performs control as shown in Tables 4 and 5.
(2) For the outdoor unit, its operation pattern is controlled as shown in Table 6 according to the room temperature category and external temperature category.
(3) If the operation status shown in Table 5 makes a state transition depending on the changes in room temperature or external temperature, the product will perform cycle
balancing with a compressor stop time as shown in Table 7.
(4) When the temperature judgment is low humidity in room temperature category 2, the product will be stopped. (The compressor stop time at that time is 3 minutes
or more.)
(5) The room temperature setting in comfortable cooling must be the external temperature less 5
℃
. Provided that, if the temperature is higher than the room temperature,
the temperature setting must be set to room temperature, with 24
℃
as the lower limit. The fan speed is set to MED.
(6) The humidity setting in dry cool must be 50% when the room temperature setting is 27
℃
or more, 55% when it is 26
℃
or more, and 60% when it is
25
℃
or more.
(7) If the product is stopped in "heating dry" or "cooling dry," the outdoor unit will run for 30 seconds with the outdoor unit pattern J.
(8) During a comfortable cooling operation with the "comfortable cooling" button of the remote control unit, pressing the "as-desired" button will light up the
"Sensitive to heat" or "Sensitive to cold" indicator, thereby activating a "Sensitive to heat" or "Sensitive to cold" operation. At that time, the temperature setting will
change as shown in Table 9.
