(2) Operations of major functional items under each operation mode
Notes(1) Compressor 2 is available on FDCJ224, 280, FDCP224 and 280 only.
(2) 嘷 : ON,⳯: OFF, 嘷 /⳯: ON or OFF
(3) This applies to when the jumper wire is shorted (state at shipping). It is OFF if the connection is open.
(4) It is fully open for one minute when the compressor begins operation.
(3) Cooling operation
(a) Cooling
1) If the sum of selected and required frequencies is not larger than the maximum frequency, the required frequencies listed in the
following table apply. If the sum of required frequencies is larger than the maximum frequency, the required frequencies divided
proportionally apply.
Frequency bands for indoor unit models
Notes (1) Frequency during cooling is 45 Hz.
(2) The required frequency is counted in the unit of 5 Hz and the selected frequency in the unit of 1 Hz.
Frequency bands for outdoor unit models
Note (1) Frequency is controlled in the unit of 5 Hz.
Compressor capacity control (only for 224, 280 models)
Note (1) In case when CM1 only changes from ON to the CM2 ON range, CM1 is reduced at 40 Hz and then CM2 is turned ON.
Model Fk (Hz) condition CM1 (Inverter) CM (Without inverter)
FDCJ224HKXE2 Fk < 70Hz 25 ~ 90Hz OFF
FDCP224HKXE2 Fk ≥ 70Hz 40 ~ 100Hz ON
FDCJ280HKXE2 Fk < 80Hz 25 ~ 95Hz OFF
