16. Ventilation module
105
Follow the steps below to install the module:
A ventilation unit can generally be connected in two different ways:
• With two-wire control, you connect the common terminal from the ventilation unit in between two control wires.
If no control wire is selected, the ventilation system will function at the lowest setting.
• With three-wire control, you connect the common terminal from the ventilation unit in between three control wires.
Each control wire represents one specific ventilation setting.
1 Press the module onto the DIN rail until it clicks into place.
2 Connect ventilation setting ‘low’ (eco) to screw terminal 1’ (only for systems with three-wire control), ‘medium’ to
screw terminal 2’ and ‘high’ to screw terminal 3’.
3 Connect the common terminal from the ventilation unit to the L screw terminals.
4 Connect the ventilation module to the module before it. Slide the sliding contact of this module to the right until it
clicks into the ventilation module. This will ensure that the bus and the power supply voltage are connected.
Programming the ventilation module
Use the programming software to select when and for how long the ventilation system should remain activated for each
setting, i.e. ‘low’ (eco), ‘medium’ and ‘high’. You can also select how long the highest setting should remain activated in
boost mode. Furthermore, ventilation control can be incorporated in other Niko Home Control functions, such as the
eco-function or calendar-based functions.
Error codes
When the module is functioning properly, the STATUS LED will light up in TEST mode only. If one or several errors occur,
the LED will blink to indicate the error code of the error with the highest priority. The table below provides an overview of
all error codes.
• Ensure that the installation is disconnected from the mains.
• Refer to the manual of the ventilation unit to check whether it should be connected using two or three
control wires.
