Detailed Description of Functions (Outdoor Unit)
(1) Startup control for air conditioning
(1)-1 Startup control (in cooling)
(1)-2 Startup control (in heating)
(1)-3 Thermostat ON/OFF by cleaning
Case of activating cleaning automatically
Cooling: Conducts cleaning on an idle machine when the thermostat of the individual
indoor unit is OFF. Capable at operation mode = 0 - 35
Heating: Conducts cleaning when the thermostat of all indoor units is OFF or at stopping
status. Under cleaning operation mode = 0, 74, 75 and 80 only. Shifts to
operation mode = 0, 29, 30 and 35
