Operation

How the Dehumidifier Works

• Compressor activates after 3-minute protection delay when room humidity ≥ (set humidity + 5% RH).
• Compressor stops when room humidity < (set humidity - 5% RH).
• Within the ±5% RH range, the unit maintains operation.
• The fan stops 3 minutes after humidity drops.
• When the water tank is full (3 beeps, indicator light on), the unit stops. Empty the tank and reinstall it properly to resume.

Defrosting

• After 30 minutes of operation, if the coil temperature is ≤ -1°C for 3 seconds, the compressor stops and the fan runs for defrosting.
• Defrost ends when coil temperature reaches ≥ 5°C for 3 minutes.

Indicator Lights

When a feature is activated, the corresponding button will be highlighted in green.

Power On/Off

When plugged in, the screen displays the current room humidity.
