Notes:
(1)
Condition for entering into Cool Dashed mode. When fan set to “Hi” or “Auto mode” and temperature difference between indoor temperature and set temperature has a
corresponding compressor speed (calculated value in Table 2) larger than CMAX.
(2) Cool Dashed will release when i) a maximum 25 minutes is lapsed and ii) room temperature is lower than set temperature –3
°
C (thermo off) and iii) when room temperature
has achieved setting temperature –1
°
C then maximum Cool Dashed time will be revised to 20 minutes. And iv) indoor fan is set to Lo and Med fan mode and v) change operation
mode.
(3) During Cool Dashed operation, thermo off temperature is set temperature (with shift value) –3
°
C. After thermo off, operation continue in Fuzzy control mode.
(4) Compressor minimum “ON” time and “OFF” time is 3 minutes.
(5) During normal cooling mode, compressor maximum speed CMAX will maintain for 60 minutes if indoor temperature is lower than CLM XTP. No time constrain if indoor temperature
is higher than CLMXTP.
(6)
(7) When fan is set to “Med”, compressor speed will be limited to CJKMAX.
(8) When fan is set to “Lo”, compressor speed will be limited to CBEMAX.
(9) When fan is set to “Silent”, compressor speed will be limited to CSZMAX.
(10) During Cool Dashed, when room temperature reaches set temperature –1
°
C compressor speed is actual speed x DWNRATEC.

When fan speed setting on remote control is “Hi” or “Auto” mode, and both room and outdoor temperatures (data based on out door unit) meet temperature judgment
(Off) shown in the table 1, the compressor speed will be limited to CKYMAX.
