"
The frequency command for every zone is stated below.
(Please note that an operation will not carry out in the commanded frequency sometimes in
case a protection control like a freeze-protection etc. will be actuated.)
3. Required fan speed
"
Fan speed changes the rotation speed every time when a thermostat switches over ON and
OFF.
"
When the thermostat becomes Off, fan continues to operate 10 minutes more with low
speed so as to prevent recovery of humidity caused by reevaporation of the drain water, and
then stops.
Night set mode
The night set mode is activated when the off timer is set. It restricts the operation frequency, to
minimize the noise.
