2. Under the following conditions, mildew guard will clear the time count and restart with initial settings.
Mildew guard starts with dehumidifier operations by turning ON the compressor and fan regardless of the present
humidity or time.
(a) The power is turned ON when mildew guard is selected (i.e.: power button is turned ON or ON timer time is reached).
(b) Mildew guard is selected with the MODE button.
(c) Mildew guard is reactivated by operating the air purifier button (Air purifier ON → OFF).
(d) Mildew guard is run for 24 hours.
3. While mildew guard is operating, the dehumidifier is deactivated under the following conditions.
(a) Current humidity below 35% detected followed by 2 hours of below 40%.
However, the accumulated time is cleared if the current humidity breaches 41% for 3 consecutive minutes during the count.
(b) Current humidity below 45% detected followed by 4 hours of below 50%.
However, the accumulated time is cleared if the current humidity breaches 51% for 3 consecutive minutes during the count.
4. After being deactivated in step 3, if the humidity level reaches 71%, the dehumidifier is automatically activated and runs
until the level drops below 65%. Below 65%, the dehumidifier remains deactivated until the humidity level again reaches
71% (limiter dehumidifier operation).
