PURPOSE
THE UNIT SHOULD NOT BE OPERATED BY CHILDREN OR PERSONS WITH REDUCED
PHYSICAL, MENTAL, OR SENSORY CAPACITIES, OR THOSE WITHOUT
THE APPROPRIATE TRAINING.
THE UNIT MUST BE INSTALLED AND CONNECTED ONLY BY PROPERLY QUALIFIED
PERSONNEL AFTER THE APPROPRIATE BRIEFING.
THE CHOICE OF UNIT INSTALLATION LOCATION MUST PREVENT UNAUTHORIZED
ACCESS BY UNATTENDED CHILDREN.
The wall control panel with a sensor display is designed for controlling industrial and domestic supply and exhaust ventilation units (AHU)
as well as other air handling units.
The control panel is not designed for standalone operation.
It is rated for continuous operation.
TECHNICAL DATA
www.blaubergventilatoren.de S25

All devices must be connected to an RS-485 network in a multidrop bus.
A single RS-485 network supports up to 16 simultaneous AHU and up to 16 control panel connections (for example, integration of one
air handling unit and several control panels over an RS-485 network allows managing the AHU from distributed control panels installed
in different rooms).
• Avoid using cables over 200 m long for RS-485 bus connections.
• Avoid connecting more than 32 devices (e.g. AHUs, external sensors, smart home system etc.) to a single RS-485 bus.
ATTENTION! COMBINING +24 V POWER LINES FROM SEVERAL AIR HANDLING UNITS IS STRICTLY PROHIBITED!

CONTROL PANEL WALL SURFACE MOUNTING
1. Route the necessary wires and cables to the control
panel mounting location.
2. Use a screwdriver to carefully press on the latch on the unit casing end
face and separate the casing halves.
DIP switch
• Rocker 1must be set to OFF. This rocker is to be only used by service engineers for programming the control panel.
• Rocker 2must be set to ON if the control panel is the first or the last device on an RS-485 bus. This rocker activates or de-activates
the terminal resistor.

The temperature sensor is an optional device which measures the temperature in the room. If physically present in the panel
configuration, select "Sensors in control panel" item in the control panel menu.

3. Route the cable through a round hole in the back
side of the panel and attach the panel to the mounting
surface. Insert the connector into the bracket.
4. Connect the power supply cable wires according to the electrical
connections diagram.

bracket and connect it to the female connector on the
circuit board.
6. Match the prongs of the lower part of the front panel with the slots in
the lower part of the back panel at 45° and join the halves until they lock in
place.

NETWORK SETUP
www.blaubergventilatoren.de S25
8
An RS-485 network is based on a multi-master principle:
• Slave devices — all the AHUs.
• Master devices — all the control panels, external sensors, a smart home system etc.
RS-485 network factory settings:
• Controller address: 1.
• Data transfer rate: 115200 baud.
• Stop bits: 2.
• Parity: none.
ATTENTION!
The RS-485 network parameters for the AHU controller are set up via the mobile application.
The factory settings enable control of a single AHU with the address using a single control panel with the address .
To use several control panels to control a single AHU or use a single panel to control several AHUs, integrate the AHUs and the control
panels in use into an RS-485 network and set it up:
1. Use the mobile application to assign a unique address from 1 to 16 for each AHU.
2. Go to the Connection window in the control panel and assign a unique address to each control panel and then select the address of
the AHU to be controlled.
Main page Menu Engineering menu Connection
Engineering menu password: 1111 (default).
Controller address: from 1to 16 — a unique address of the AHU to be
controlled.
Control panel address: from 1to 16 — a unique address for each control
panel.
Note: the control panels and the AHUs are addressed independently.
The RS-485 network parameters (Baud rate, Stop bits, Parity) set for the
AHU controller and the control panel must be identical.
If the RS-485 network parameters are set incorrectly or if there is a problem
with the cable, the display will show a warning ("No communication with the
device. Check the connection").

Set threshold values for the humidity, CO, PM2.5, and VOC sensors.
The unit will automatically maintain the user values by smoothly increasing
or decreasing the fan speed.
Main page Menu Basic settings Timers
Once the Main timer is enabled via the Main page menu, the air handling
unit temporarily switches to the following settings:
