COMFORT 300 TOP BY NILAN
The large door provides easy access
for changing filters and cleaning the
unit.
Intelligent humidity sensors provide
an option for controlling the ventilation as required, based on the average
air humidity in the home.
Counterflow heat exchanger made of
polystyrene, which has a higher temperature efficiency than aluminium
exchangers.
The unit comes with a clear and
user-friendly operating panel.
The powder-coated condensate drain
prevents the formation of “acid water”
and allows the condensate to be
drained away.
The modern CTS 602 control panel
runs Modbus communication.
Filter monitor with timer.
The efficient fans are powered by
energy-saving EC motors.
G4 filters are supplied as standard, but it is
also possible to buy a duct mounted F7
pollen filter as an accessory.
They provide a constant air volume
with a four-step adjustment.
The automatic bypass damper makes
the outdoor air bypass the heat
exchanger when heat recovery is not
required, thereby saving energy.
The CTS602 control can control an
external water-based or electrical
heating element.
Bypass cooling as an option.

AUTOMATION
CTS 602 Control
The Comfort 300 Top is controlled by using the CTS 602 operating panel, featuring a wide range of functions, e.g., menu-controlled operation, weekly programme settings, filter monitor
with timer, fan speed adjustment, summer bypass (free cooling), post-heating element control, error messages etc.
The CTS 602 comes with factory settings, including a default
setting which can be customised to operational requirements
to achieve optimum operation and utilisation of the system.
The operating panel must be placed in a dry, frost-free loction,
at least 1.5 m above floor level and at least 0.5 m from any
corner. Avoid placing the panel on an external wall or in areas in
direct sunlight.
Operating instructions for the CTS 602 can be found in a separate user manual supplied with the unit.

COMMUNICATION
External communication
The CTS 602 control unit communicates by default with
Modbus RTU RS485 communication. A CTS system using this
form of communication can easily be connected to the unit.
Nilan units have an open Modbus communication, i.e. not only
can the unit be monitored, but its operation can also be set in
the same way as it can via the operating panel.
CTS / Computer
Konverter
Modbus
The protocol is set up by default for a Modbus RTU 30
address, but can be set to a value between 1 and 247.
A Modbus converter allows you to connect one or more units
to a computer to monitor and control the unit.
OPERATION
Intelligent humidity control
Nilan’s humidity control automatically adapts to the needs of
the family or the building.
This ensures that the unit always runs at its most efficient,
based on the actual air humidity level and not on a theoretical
one.
This helps save energy because it automatically adapts to the
requirements in the home. Whether a large family or a single
person is living in the building has a considerable influence on
how much humidity is produced.
The unit also adjusts automatically to summer and
winter level.
Immediately change in % of RH
The intelligent CTS 602 control unit does not need to have a set
level input for air humidity (RH) to control the air exchange. By
using the integrated humidity sensor, the control unit calculates the average level itself for the last 24 hours. The average
level provides a basis for deciding whether to change the air
exchange if the air humidity fluctuates.

OPERATION
COMFORT 300 TOP BY NILAN
Frost protection
All ventilation units with a counterflow heat exchanger will ice
up if the outdoor temperature is below freezing for a
prolonged period.
ɳt[%]
Consideration must be given to whether the unit’s operation
can be protected during a lengthy period of frost or whether it
is acceptable to decrease its operation.
With pre-heater
Temperature efficiency
The extracted air condenses when it is cooled down during heat
recovery. The high temperature efficiency will slowly turn the
condensate to ice, which will block up the counterflow heat
exchanger unless action is taken to remedy this.

In homes which are occupied at night, it would be advisable
to protect the unit against frost when the outdoor temperature is coldest by using a pre-heating element. On the other

ACCESSORIES
Water heating element incl. regulation
The supply temperature can always be raised to the required level using a water
heating element. The water heating element is designed to be built into the duct and
must be connected to the primary heating supply. Supplied with two-way adjustment valve, temperature sensor and frost thermostat.
Electrical heating surface incl. regulation
When you fit an electrical heating surface, you can raise the fresh air temperature
to the desired level at any time. The electrical heating surface is supplied ready to
fit into the fresh air duct and, for easy fitting, the device is pre-fitted with all the
required sensors.
Electrical pre-heating element (Frost protection)
An electrical pre-heating element heats up the outdoor air before it enters the unit.
This avoids having to defrost the unit, resulting in a loss of power.
There are temperature sensors supplied to be fitted in the ducts.
EM-box
An EM-box allows heat recovery from the air from the range hood and thereby helps
to heat the supply air. The EM-box is equipped with a special filter which efficiently
cleans the range hood air of fat particles and thereby protects the system.
Expansion PCB
The expansion PCB provides additional functions for the CTS 602 control unit, e.g.,
controlling the EM box (see list of functions on page 7).
Pollen filter box
Insulated pollen filter box with F7 pollen filter and Ø160 mm connection pieces. The
pollen filter box must be installed on the inlet duct after the Comfort 300 Top unit.
Installation kit
The installation kit comprises of four vibration absorbers and a water trap for the
condensation outlet. The water trap can be ordered separately.
Heating cable
To protect the condensation outlet against frost, a 3 metre-long self-regulating
heating cable can be ordered.

DELIVERY
AND HANDLING
COMFORT 300 TOP BY NILAN
Transport and storage
Comfort 300 Top comes in factory packaging that protects it during transport and storage.
Comfort 300 Top must be stored in a dry place in its original packaging until installation.
The packaging should only be removed immediately prior to installation.
Installation conditions
During installation, future service and maintenance should be
taken into account. We recommend a minimum gap in front of
the unit of 60 cm.
Min. 50 cm
Min. 60 cm
The unit must be installed level for the sake of the

Installation of electric
heating element
Electric heating elements (accessories) are fitted in the duct. The
fitter should ensure that there is a safe distance of at least 15
cm between the electric heating element and any inflammable
material. The heating element must be insulated using
fire-resistant insulation material.

NILAIR
NilAIR is installed together with a ventilation unit,which in simple
terms consists of distribution boxes from which tubes are led out
to air extraction and air supply boxes in the individual rooms.
NilAIR can be installed in ceilings, walls or floors. The lightweight
tubes can be used for even the most complicated tube alignments, where e.g. traditional spiral ducts cannot be used.
Advantages
Enabling the impossible
• Flexible and space-saving solution
• Rapid and simple installation with a click system
• Dimensionally stable and corrosion-resistant quality material
• Simple regulation of the air supply volume
Traditional air distribution systems take up a lot of space and
often make special building structures impossible. NilAIR virtually eliminates this problem, due to the tubes’ size and flexibility.
• Low weight
• Airtight
• Easy to clean
• Easy to handle and transport
• Prevents sound travelling from room to room
NilAIR is already installed in thousands of European homes and
since its introduction more than ten years ago its use has steadily increased, due to the rapid and easy installation without any
special tools being required.
