Heating Mode Operation• When the compressor is stopped by Remote Control, it restarts after 3 minutes when the Remote Control is turned ON.• When the setting temperature is reached during heating operation, the compressor stops and it will not start for 4 minutes.• The compressor will start automatically if it has stopped for 30 minutes even if the room temperature is between the compressorON temperature and OFF temperature.(a) Outdoor Fan Control• A12CTIf the temperature of the indoor heat exchanger rises to 51°C, Outdoor Fan stops.The Outdoor Fan restarts when the indoor heat exchanger temperature falls to 49°C.• A18CT, A24CTIf the temperature of the Outdoor Heat Exchanger less than -3°C, Outdoor Fan is ON. The Outdoor Fan stop, when OutdoorHeat Exchanger temperature is T b or more according to Outdoor Air Temperature region as table below:The Outdoor Fan restarts when the indoor heat exchanger temperature falls to 49°C.During starting of Heating mode and after deice, Outdoor Fan ON for 90 sec.(b) Compressor high pressure protection• If the indoor heat exchanger becomes 65°C (A12CTP); 68°C (A18CTP & A24CTP) or more, the compressor will stop andrestart automatically.(Time Delay Safety Control - 4 minutes waiting).• If the compressor is operating continuously for 5 minutes or longer and temperature difference between intake air and indoorheat exchanger is 5°C or less for 2 minutes, compressor will stop and restart automatically.(Time Delay Safety Control is valid). T = Indoor heat exchanger temperature - intake air temperature.This is to protect reverse rotation of the compressor when there is a instantaneous power failure.24CS-A12CTP CU-A12CTP5 / CS-A18CTP CU-A18CTP5 / CS-A24CTP CU-A24CTP5
