Notes:
(1) Cool dash is started when the operation is started at fan speed "AUTO" or "Hi" or when the fan speed is changed to "AUTO" or "Hi" during cooling operation, and when the
compressor speed reaches CMAX or higher.
(2) The maximum compressor speed period during cool dash is finished
①
when 25 minutes have elapsed after cool dash was started
②
when the room temperature reaches
the cooling set temperature -1˚C (including cooling shift) and then becomes lower than the preset temperature by 0.66˚C after the steady speed period,
③
when thermo is
OFF.
(if cool dash finished in the above
①
, the compressor does not go through the steady speed period but it starts fuzzy control.)
(3) The thermo OFF temperature during cool dash is cooling set temperature (including cooling shift) -3˚C. After thermo OFF, cool dash is finished and fuzzy control starts.
(4) The compressor minimum ON time and minimum OFF time is 3 minutes.
(5) The time limit for which the maximum compressor speed (CMAX) during normal cooling can be maintained is less than 60 minutes when the room temperature is less than
CLMXTP: it is not provided when the room temperature is CLMXTP or more.
(6) If the fan speed is set to "Med" by remote control, the maximum compressor speed is CJKMAX.
(7) If the fan speed is set to "Lo" or "Silent" by remote control, the maximum compressor speed is CBEMAX.
(8) If the fan speed is set to "Hi" by remote control and both the room temperature and outside temperature (data from the outdoor unit) satisfy the condensation condition in Table
3, the maximum compressor speed is CKYMAX.
(9) While the cooling thermo is OFF, the indoor fan speed is maintained at the preset fan speed.
