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 (P item) reaches (CMAX1 or CMAX2) 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℃ (including cooling shift) and then becomes lower than the preset temperature by 0.66℃ 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℃. 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 (CMAX1 or CMAX2) 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) Compressor speed is determined by instruction sent from indoor unit and corrected by outdoor unit according to such factors as capacity, fan speed, number of units being operated, outdoor temperature,
etc.
(7) If another indoor unit is doing heating operation, cooling operation cannot be done.
