A. FUNCTIONS
1. TEMPERATURE SHIFT
Once the operation starts, the remote control setting temperature will be shifted internally based on the setting fan speed and outdoor air temperature. In addition, if Sleep Mode or Powerful Mode are set, the temperature shift will be carried out. Setting of Internal Setting Temperature The internal setting temperature can be decided as follows: Remote control setting temperature + Outdoor temperature shift (refer Table a) + Fan speed shift (+ 1.0 °C) + Any Sleep Mode shift operation? + Any Powerful Operation shift? (refer Table b) + [Check upper/lower (33°C/16°C) limit for setting temperature] INTERNAL SETTING TEMPERATURE Table a Setting Temperature Shift based on outdoor air temperature.

Compressor OFF temperature = compressor ON temperature. The operation frequency changes every 30 seconds. When the difference of the intake air temperature and Internal setting temperature is 1.5°C or more, compressor will operate at Fh continuously for 3 minutes and then change over to Fhmax. The compressor stops when the intake air temperature reaches 1.5°C above internal setting temperature and continues for 3 minutes. When the compressor stops, it will not start operation for 3 minutes. (Time Delay Safety Control) When the intake air temperature decreases to the compressor ON temperature, the compressor starts immediately. When the compressor stops, the outdoor fan motor stops 30 seconds later.
