nector:
• User selection 1 og 2

There is a 0.5 meter cable from the box to an RJ45 plug, which is connected directly to the ventilation unit.
The Comfort ventilation unit has a function in its control system that can control 1-2 fire dampers.
If you want to activate this function, Nilan can supply you with a Fire Connection Box, with the following
connection options:
• Connection of 1-2 fire dampers
• Connection of external fire thermostat
• Connection of user selection 1 (cooker hood)
• Connection of Modbus communication to, for instance, CTS unit
You connect the box up with the supplied 1 m cable with RJ45 connector.
It is important to ensure that the ventilation unit does not transfer vibrations to the building. The ventilation
unit should therefore be placed on a vibration absorbing material.
Nilan can supply effective vibration absorbers to place under the ventilation unit. They are sold in packs of 4.
To make it esay to service the unit in the future, we recommend that you fit a flexible connection between the
unit and the duct system.
Nilan flexible sound damper absorbs sounds effectively from both the duct system and from roof stacks.
The ventilation unit comes, as standard, with a plate filter to protect the unit.
If the dwelling is used by anybody with, for instance, pollen allergies, you may benefit from purchasing a
pollen filter. This should be placed in the outdoor air intake, which will reduce the pollen count in the dwelling.
If the extract air needs extra filtration, Nilan can supply a Cooker hood filter box.
This can provide extra protection of the ventilation unit if you connect a cooker hood that has not got good
filters. It can also help air extraction from, for instance, dormitory rooms where cooker hoods are rarely
installed.
