Page 5 The instructions can be downloaded from www.nilan.dk. If you have questions regarding installation and operation of the unit after having read the instructions, please contact your nearest Nilan dealer. A list of Nilan dealers is available on www.nilan.dk. ATTENTION The unit must be started up immediately after installation and connection to the duct system.

Page 10 If you want to adjust the fan speed level in accordance with the level of use of the dwelling/building (amount of people), you can retrofi t a CO sensor. Nilan’s CO sensors calibrate automatically. On the control panel, you select the CO level you want.
Page 11 Fire connection box The Comfort ventilation unit has a function in its control system that can control 1-2 fi re dampers. If you want to activate this function, Nilan can supply you with a Fire Connection Box, with the following connection options: •...
Page 12 You can control your ventilation unit with a smartphone app via a gateway connection. Connect the Nilan Gateway to a CTS400 or a CTS602 control system. This way, a cloud connection to the unit can be established. The Gateway is available in two different versions - with either a LAN or a WiFi...
Page 13 Set-up Installation Positioning of the ventilation unit Positioning of the ventilation unit ATTENTION When positioning the unit, you should always consider future service and maintenance. Therefore, we recommend that ﬂ exible connections be fi tted between the ventilation unit and the duct system so that the unit can be easily removed.
Page 14 It is important that the unit is mounted on a surface level. Duct connections Duct connections An inlet ring needs to be fi tted (not supplied by Nilan). 1. Use size Ø160mm inlet ring. The Polar version is delivered 2. Press the inletrings fi rmly into the ventilation nozzles.
Page 15 Electrical installation Electrical connections Safety Safety ATTENTION All work must be carried out by qualifi ed persons and in compliance with existing legislation and regulations. ATTENTION It is important that the power is off, if you do work to the electrical components of the unit. It is important to check that wires are not damaged or squeezed during connection and use.
Page 16 Nilan offers a connection cable with RJ12 plug of 15 m. It is also possible to customize a cable up to 50 m in length. A standard LAN cable is used for this.
Page 17 Wall bracket Wall bracket Mount the HMI panel on the wall using the integrated wall bracket. The panel should be placed in a visible spot so it is possible to change settings and to monitor warnings or alarms regarding ope- ration of the unit.
Page 18 If you adapt an RJ45 cable yourself, be aware that wire 8 (Brown) can become live with 12V and must not be short circuited. In Nilan’s LAN cable the wires that are not used are not connected up to the RJ45 connector. With Nilan’s LAN cable there is therefore no risk of short circuits.
Page 19 There you can then have a switch that is activated and the ventilation is increased e.g. for an hour before it then goes back into operation. Connection via Nilan Functional cable Green/white Green...
Page 20 The CTS602Light control system has open Modbus RS485 communication that allows you to communicate with and control the ventilation unit via external control systems. Please consult the software instructions and the Modbus protocol for further information on settings and registers. Connection via Nilan Functional cable Green/white Green...
Page 21 EM-Box (damper option) EM-box (damper option) Dimensional drawing: If it is desired to run the cooker hood over the ventilation system, it may in some cases be diffi cult to get enough air for the cooker hood. With an EM box installed and when the cooker hood is in operation, you can regulate the extraction so that less air is extracted out of the other rooms, e.g.
Page 22 DTBU (damper option) DTBU (damper option) If it is desired to run the cooker hood over the ventilation system, it may in some cases be diffi cult to get enough air for the cooker hood. To solve that challenge, an EM-box solution can be used. However, if there is not enough space in the installation for an EM box, you can alternatively connect a DTBU damper in the duct system, which has the same function, except that it does not have a built-in dirt fi lter.
Page 23 5. Connect the wires up in accordance with the wiring diagram. ATTENTION The expansion PCB and the connections must be installed by a certifi ed electrician. The expansion PCB is an accessory for the CTS602 circuit board. Nilan does not supply external components.
Page 24 External electrical pre-heating element External electrical pre-heating element It is possible to purchase an external electrical pre-heating element for frost protection of the ventilation unit. The electrical pre-heating element is mounted in the outdoor air duct before the unit with the necessary temperature sensor. If it is desired to see the actual outdoor air temperature on the control panel, the temperature sensor T1 / T8 must be led out into the duct before the pre-heating element.
Page 25 Electrical after-heating element Electrical after-heating element If you want to control the supply air temperature, you will need an after-heating element. You can purchase an electrical after-heating element for installation in the supply air duct. It comes with the required sensor, an expansion PCB and connection to the ventilation unit.
Page 26 Water after-heating element Water after-heating element If you want to control the supply air temperature, you will need an after-heating element. You can purchase a water after-heating element for installation in the supply air duct. It comes with the required sensor, an expansion PCB and connection to the ventilation unit.
Page 27 sensor sensor If the extent to which a dwelling/building is used varies considerably, you will benefi t from installing a CO -sensor to control the air exchange. The CO -sensor measures the CO -level in the extract air. It then regulates the fan speed level accordingly. ATTENTION In order to be able to connect up a CO -sensor, the ventilation unit must have an expansion PCB.
Page 28 USEFUL INFORMATION As an accessory, Nilan can supply a water trap with ball. When the water trap dries out, the ball closes it off and ensures that air cannot be drawn into the ventilation unit. When condensate water is formed again, it will lift the ball, and the water will be able to drain away without problems.

If the water trap is placed outside the climate screen, it should be protected against frost. Water trap and accessories: 1.

Page 33 Note that the two extra wires from dampers (S3 and S5) are not used. Connect the supply voltage from Neutral and relay 5 in a parallel circuit. Mount junctions in an external junction box (not supplied by Nilan). Connect up S1-S6 to Nilan’s Fire Connection Box as shown under “Connecting fi re dampers”. Fire damper 1 Fire damper 2...
Page 34 Start-up and annual testing Start-up and annual testing It is necessary to carry out a complete test of functions after installation of the fi re protection automation system. If everything has been installed in accordance with the guidelines and regulations, and the test reveals no errors, the display will show “OK”. If the test fails, the display will show “ERROR”.
Page 35 Schedule for functional testing Schedule for functional testing ATTENTION DS 428 requires written documentation of the annual test of the Fire automatic system. Date: Comments: Tested by:...
Page 36 Nilan can supply Soundﬂ ex tubes that you can use as ﬂ exible connections between the ventilation unit and the duct system. They will also reduce sounds from the system considerably.
Page 37 Supply air Supply air Install supply air valves in living areas. Place them strategically so they cause minimum discomfort. It is, for instance, not recom- mended that you install supply air valves in areas where people are inactive, as the supply air may be experienced as draughty. Living areas may be, for example: •...
Page 38 Balancing Important information Important information ATTENTION To ensure the ventilation system operates optimally, it is important that it is balanced correctly. We recommend that experts do this. It is important to measure the total supply air and the total extract air. The system must have a minimum vacuum, which means it draw out more air than it blows in.
