Minimum wall thickness for mounting DUKA One Pro 25 S Wi-Fi

If the wall thickness is below the minimum requirement, it is recommended to purchase DUKA One Spacer.
Recommended distance between motor and core is 60 mm as this provides optimal heat recovery.
Position of the core in relation to the wall thickness:

Hole diameter (for mounting) 105-125 mm
Length of ceramic core and motor 165 mm
Minimum wall thickness 165 mm

• V = Wall
• L = Channel length
• T = Wall thickness
• I = Sound insulation
• M = Motor
• K = Core

3 - Use the included template for easy marking of required drill holes for mounting and entry for hidden cabling.

4 - Remove the front cover by pressing the buttons on the top and bottom.

5 - Mount the electronics with the supplied screws and remove the left cover plate.

6 - Connect the cables according to the electrical diagram and route them as shown below. Remember to relieve the cables with the cable clamps.

Pairing devices

Interconnecting units in a master/slave relationship provides synchronous operation and balanced ventilation in the home.
For paired devices, only the master device can be controlled via app, remote control or on the electronics. Slave devices will only respond to the signal they receive from the master and ignore other signals.

To pair units, press and hold the ventilation button on the side of the mounted unit for 5 seconds, after which the unit will beep and the diodes on the side will start flashing. This is done first for the master unit and then for subsequently mounted slave units. After pairing, a slave unit will beep and the LEDs will stop flashing.

When pairing is complete for all desired slave units, press and hold the ventilation button on the master unit and wait for the beep, after which the LEDs will stop flashing.

NOTE - If you want to control the devices over the home network, it must be set up for the master device BEFORE pairing the devices. The devices can be paired within the local network.

Operation

Front cover features and control panel

By clicking the bottom, top or side of the front cover of the device, you can determine the blowing direction.
Note: The device is most effective when it is open on all sides.
NOTE: If the airflow needs to be shut off for safety reasons, the entire front must be closed and the unit switched off periodically.
