5. Operating Instructions
5.1 Control Panel
The unit features an intuitive digital control panel for easy operation.

Key functions on the control panel typically include:
- Power Button: Turns the unit ON/OFF.
- Humidity Setting Buttons (+/-): Adjusts the desired humidity level (e.g., 30% - 90% RH).
- Timer Button: Sets the operating time (e.g., 1-24 hours) or delay start.
- Display: Shows current humidity, set humidity, or timer settings.
- Indicator Lights: May include 'Tank Full', 'Continuous Operation', 'Defrost', and 'Timer' indicators.
5.2 Initial Operation
- Plug in the unit.
- Press the Power button to turn on the dehumidifier.
- The display will show the current room humidity.
- Use the humidity setting buttons to set your desired humidity level. The unit will operate until this level is reached, then cycle on and off to maintain it.
5.3 Dehumidification Modes
- Automatic Mode: The unit operates until the set humidity level is reached, then pauses. It restarts automatically if the humidity rises above the set point.
- Continuous Operation: If available, select this mode for continuous dehumidification regardless of the humidity level. This is often used for severe moisture problems or during water damage restoration.
- Timer Function: Use the timer to set a specific operating duration (e.g., 2 hours) or to delay the start of operation.
5.4 Water Drainage
The TROTEC TTK 171 ECO offers two methods for water drainage:
- Internal Water Tank: Condensed water collects in the removable internal tank. When the tank is full, the unit will automatically shut off and an indicator light will illuminate. Empty the tank and reinsert it to resume operation.
- Continuous Drainage: For extended operation without manual emptying, a drainage hose can be connected to the unit to direct water to a floor drain or larger container. Refer to the unit's side panel for the drainage outlet.
