Min. required frequency
Note (1) Value in ( ) are for the models FDC125VSX, 140VSX.
(b) Heating operation
Max. required
frequency
Min. required frequency
(c) If "Silent mode start" signal is received from the remote controller, the maximum required frequency becomes same as
when the indoor air flow is set at "Lo".
(d) Max. required frequency under high outdoor air temperature in cooling mode
Maximum required frequency is selected according to the outdoor air temperature (Tho-A).
Max. required
frequency
(e) Max. required frequency under outdoor air temperature in heating mode
Maximum required frequency is selected according to the outdoor air temperature (Tho-A).
Max. required
frequency
(f) Selection of max. required frequency by heat exchanger temperature
1) Maximum required frequency is selected according to the outdoor unit heat exchanger temperature (Tho-R) during
cooling/dehumidifying or according to the indoor unit heat exchanger temperature (Th
2) When there are 3 indoor unit heat exchanger temperatures (Th

(g) When any of the controls from (a) to (f) above may duplicate, whichever the smallest value among duplicated controls is
taken as the maximum required frequency.
(h) During heating, it is operated with the maximum required frequency until the indoor unit heat exchanger temperature
becomes 40°C or higher.
