Unit type
Product description
Comfort CT150 / CT200 is a ventilation unit with heat recovery. It is useable for air volumes up to 175 /
200 m 3 /h at 100 Pa external duct pressure.
The unit extracts humid and poor quality air from the home via the bathroom, toilet, kitchen and utility
room, and blows fresh air into rooms such as the lounge, bedrooms and office. Cold outdoor air is
heated in the heat exchanger by the warm extracted air.
Comfort CT150 / CT200 comes as standard with a plate filter for outdoor air and extract air. If you
want to filter pollen from outdoor air, a pollen filter is available for retrofitting.

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.
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.
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.
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.

Side mounted brackets for vertical mounting
For vertical mounting of the unit a wall bracket can be purchased and attached in
which the ducts can also be led and concealed. By vertical mounting the unit
works as a top-unit.
The side panels are prepared for mounting of the display panel.
Rear mounting brackets for vertical mounting
A wall bracket can be purchased and attached for mounting on the back of the
unit. By vertical mounting the unit works as a top-unit.

Installation
Mounting
Positioning of the unit
ATTENTION
When mounting the unit, consideration must always be given to future servicing and
maintenance.
It must be easy to replace filters, and it must be possible to perform tasks such as removing the heat
exchanger, replacing fans and other components.
ATTENTION
A minimum free space in front of the unit of 60 cm is recommended.
Comfort CT150 is a flexible unit which can be mounted horizontally, vertically or at an angle. However,
it is important that the exhaust is always positioned at the bottom (see illustration below).
ATTENTION
The system must be mounted in a level position. If this is not possible, there must be a decline
towards the condense water outlet.
Errors in the installation can cause moisture and water damages.
Systems that are not mounted on a walls or ceiling, MUST be mounted on a level and firm
surface.

Installation rails
Comfort CT150 is always supplied with a set of installation rails.
The rails must be mounted with a space between them of 1045 mm. The unit is then slid between them
and fixed by turning up the ends of the rails.
This is a simple and quick way of mounting the unit without having to hold it while screwing it into
position.
1045 mm
Rear installation (accessories)
It is possible to buy a mounting bracket, for mounting on the back on the unit.
It is a good solution, if the unit has to be installed vertically in a cabinet or a technical room. In this way,
the unit is converted to a "Top unit".

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.
