Cooling
*Both capacity and input decrease when temperature is 19 or less degrees C, for compressor
frequency restrictions operate.
*Both capacity and input decrease when temperature is 40 or more degrees C, as compressor speed is
decreased due to current release protection.
*Both capacity and input change largely when temperature is 10 or less degrees C, as outdoor fan speed
is decreased due to low ambient temperature cooling control.
*Both capacity and input change more largely at less than 0 degrees C of ambient temperature as
outdoor fan speed is decreased further.
