Airing of buildings are becoming ever more important due to the continued improvement of
airtight building envelopes. The consequence of this energy-saving building method is that the
air humidity, which is formed in the day to day use of a room can no longer escape su󰀩ciently.
Dampness can thus form and cause damage, at worst resulting in mould and fungi growth,
which deteriorates air quality and can become a health hazard.

For the dehumidifying of buildings, ventilation systems of di󰀨erent types and performance
levels are used. Temperature and humidity sensors compare the internal and external
temperatures and humidity. A Controller compares these values.
At higher humidity in the building, using a load relay, a ventilation system is switched on.
The ventilation is only switched on if the humidity outside is less than inside, thus making the
drying process of the area possible.

The bioxX dehumidifying controller bx-ESG can be used in both home and the commercial
sector. Ensure that dampness due to defective construction parts, gutters, roofs etc.
is avoided; this can be achieved by routine repairs. The bx-ESG can also be used for
temperature control of cellars, restaurants, o󰀩ces and dwellings (minimum and maximum
temperature).
Home/Oce
• Ventilating of rooms with high air humidity (e.g. Laundry rooms)
• Dehumidifying of dampness due to dense construction cover
• Dehumidifying of condensation on walls, oors and construction units that don’t t ush.
• Basic ventilation for humidity purposes (living spaces)
Commercial Sector
Additionally the dehumidifying controller can be used to operate industrial aerators and
ventilation systems up to an output of 1800 W humidity.
1.3 Warranty and Adhesion
bioxX system GmbH o󰀨ers a two years warranty on factory defects and components of the
controller.
Repairs and maintenance should only be done by professionals.

4. Initial Setup
Test the functionality by rst plugging the sensors into the power supply, before beginning the
complete assembly.

The controller is to be attached to a dry wall where it is well accessible and close to a wall
socket.
The external sensor must be rain-protected and above the splash-water range (50 cm),
preferably at the north side.
Direct sun exposure misrepresents the result of measurement due to heating.
The interior sensor must be attached in the area with the largest humidity load. This also
applies to the optional 2nd interior sensor.
When using the bx-ESG as temperature control the interior sensor must be in the area with
the largest thermal load (e.g. to attach within the upper part of the room).
4.2 Assembly
• Mark the wall where holes should be drilled
• Drill and insert expansion anchors
• Turn provided screws into the two upper holes and let the screws stand out 3 mm
• Hang the controller on the screws
• Loosen the two lower screws on the housings, which removes the lower cover to open
the housing
• Turn the bottom two screws in to x the housing to the wall
• Connect the potential-free contact (as a rule the live wire) to the lustre terminal
(see connection diagram)
• Pull the live wire from the lustre terminal to the air ventilation system
• Attach Sensor cables
• Raise the cover cap on the sensor to open it
• Fasten the sensors with the enclosed expansion anchors and screws
• Fasten the sensor cables
• Input the cables into the sensor and close the cap
• Plug in power supply
• Press the red button with the gears on it on the controller to get to the basic installation
• Exit the basic installation menu by pressing the red button with the gears on again
