Unit type
Product description
Comfort 200 Top is a ventilation unit with heat recovery. The unit is intended for air volumes up to 308
m3/h3/h at 100 Pa external duct pressure.
The unit extracts humid and vitiated air from the dwelling via the bathroom, the lavatory, the kitchen
and the utility room. It blows fresh outdoor air into living areas such as the living room, bedrooms and
the home-office. Cold outdoor air is heated in the heat exchanger by warm extract air.
As a standard, Comfort 200 Top is supplied with plate filters in outdoor air and extract air. If you want
to filter out pollen from the outdoor air, a pollen filter can be purchased as an accessory and be
retrofitted.

Accessories
Electrical pre-heating element for frost protection
In longer periods of sub-zero temperatures, the high-efficiency counterflow heat
exchanger will ice up. To avoid icing, it is recommended that an electrical
preheating element is mounted.
The pre-heating element uses very little energy, but it ensures efficient heat
recovery without de-icing. You therefore achieve an overall reduction of energy
consumption.
Water after-heating element incl. regulation
With a water after-heating element you can increase the supply air temperature
to the desired level. The water after-heating element is for duct mounting and
should be connected to the primary heat supply.
It is supplied with a two-way regulation valve, a temperature sensor and a frost
thermostat.
Electrical after-heating element
With an electrical after-heating element you can increase the supply air
temperature to the desired level. Electrical after-heating elements are supplied
for mounting in the supply air duct. Included are the necessary sensors.
EM-box
With an EM box it is possible to divide the extract air between the kitchen and the
bathroom.
If a cooker hood is connected to the unit and is switched on, extract air from the
bathroom will be reduced slightly to allow sufficient air for the cooker hood to
extract kitchen fumes.
The EM-box has a fitted metal filter that clears the air in the cooker hood of
grease particles effectively, and thereby protects the unit.
DTBU-damper
If there is insufficient space in the installation to fit an EM-box, Nilan can provide
aDTBU-damper that can be fitted between kitchen and bathroom. It has the
same function as the EM-box, but you will have to run longer wires.
10

Pollen filter
As a standard, the unit is supplied with a plate filter.
If anyone in the household suffers from a pollen allergy, you can install a pollen
filter in the outdoor air intake to minimize the proportion of pollen in the indoor
air.
A pollen filter also removes approx. 50 % of harmful particles in outdoor air, so a
pollen filter is recommended if you live in a large city or close to a motorway.
Water trap
To ensure that condensate water can drain freely, a water trap must be installed.
You should check regularly that there is water in the trap. The water trap may
dry out during late spring, summer and autumn, when no condensation is formed.
If the water trap dries out, air will be sucked into the unit and condensate water
will not be able to drain. This will cause water damage.
Nilan’s water trap contains a ball that ensures that no air is sucked into the unit
and that condensate water can drain freely.
Vibration absorbers
Four vibration absorbers are placed under the unit to ensure effective softening
of the vibrations of the unit against its foundation.
Flexible sound damper
To make it easy to service the unit in the future, we recommend that you fit a
flexible connection between the unit and the duct system.
Nilan's flexible sound damper absorbs sounds effectively from both the duct
system and from roof stacks.
CO2-sensor
With a CO2-sensor installed, the fan speed can be pre-programmed to run at a
higher level when there is high CO2 - level in the extract air. CO2 level can be
programmed.
The CO2 -sensor must be ordered factory-fitted.

Set up
Installation
Positioning of the unit
ATTENTION
When positioning the unit, you should always consider future services and maintenance.
It must be easy to change filters, and it must, for instance, be possible to remove the heat
exchanger, and to replace fans or other components.
ATTENTION
An open space of minimum 60 cm in front of the unit is recommended.
ATTENTION
The unit must be level to enable proper drainage from the condensate tray.
The unit makes little noise and produces only weak vibrations, but you should still take into account
potential vibrations that can spread from the unit to individual building components. In order to
separate the unit from its foundation, it is therefore recommended that you install vibration absorbers
under the unit. There should be approx. 10 mm distance to other building components and to
permanent fixtures.

Electrical connection accessories
Connection to user selection and Modbus
User selection: Connection to user selection can be used, for instance, for controlling a cooker hood.
This happens via a potential free contact in the cooker hood that sends a signal to the unit, which, in
turn, increases ventilation when the cooker hood is on. You connect it using pin 4 and 5 in the 8 pole
plug of the control panel.
User selection can also be used for other functions such as to create imbalance in supply air and extract
air ventilation.
Modbus: You can communicate with the unit via Modbus, which can be connected in pin 1 (GND), pin 6
(A1) and pin 7 (B1) in the 8 pole plug of the control panel.
Please, consult user manual for software settings etc.

External electrical pre-heating element
If your unit is not the Polar version with an integrated pre-heating element, you can purchase and
retrofit an external electrical pre-heating element.
The electric preheating element is mounted in the outdoor air duct before the unit with the necessary
temperature sensor.
1x230V ~ 50 Hz max. 16A

Min. 25 cm
T
It is important that the sensor is placed at least 32 cm from the preheating element to achieve correct
regulation.
The pre-heating element has a three-step safety system that prevents
overheating.
1. An operating thermostat regulates the heating and ensures that the supply air
temperature does not fall below -1 °C
2. Should the temperature exceed 50 °C, a max. thermostat switches off the pre-
heating element. (If installed vertically with downward airflow, the pre-heating
element switches off at 70 °C)
3. A safety thermostat switches off the pre-heating element if the temperature
exceeds 100 °C. Then, you must reset it manually.
ATTENTION
The heating element must be insulated with a fire retardant insulation material. The cover of
the connection box, however, must not be insulated.
