With an expansion PCB, it is possible to expand the functions within the control system.
• Connecting an after-heating element (supplied with the heating element)
• Connecting a CO
2
-sensor
• Connecting a joint alarm
Following external functions are connected to the ventilation unit via a Connection Box with a RJ45 connector:
• User selection 1 og 2
• Modbus communcation
• Fire thermostat or external fire automation system
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 con-
nection 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.
If you want to run the cooker hood function simultaneously to the fire automation system, Nilan can supply a
separate Connection box that can be connected up to the Nilan Fire Connection Box.
The box comes with a 2 metres power cable.
If you install the ventilation unit outside the climate screen, it is important to protect the condensate drain
from frost.
Nilan can supply an external heating cable that you run along the exterior of the condensate drain before
insulating it. This way you will have a frost free condensate drain that does not get blocked. The heating
cable has an integral thermostat that regulates the level of heating in accordance with the temperature of
the surroundings.
The cable is available in two lengths: 3 m or 5 m.
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.
