Notes:
(1) Condition for entering into Cool Dashed mode. When fan set to "Hi" or "Auto and when the compressor speed (P section) due to temperature difference between setting
temperature (including the correction shift only) and room temperature is CMAX or higher.
(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 rpm CMAX will maintain for 60 minutes if indoor temperature is lower than CLMXTP. No time constrain if indoor tem-
perature is higher than CLMXTP.
(6) When fan is set to "Hi", compressor rpm will be limited to CSTD.
(7) When fan is set to "Med", compressor rpm will be limited to CJKMAX.
(8) When fan is set to "Lo", compressor rpm will be limited to CBEMAX.
(9) During Cool Dashed, when room temperature reaches set temperature –1°C compressor rpm is actual rpm x DWNRATEC.
