COMFORT 1200
The Comfort 1200 is a ventilation unit suitable for central ventilation of residential buildings, schools, offices and business facilities with a ventilation requirement of up to 1400 m3/h.
Every component has been carefully selected with a view to unsurpassed quality and each component is tested throughout the
entire production process, as are the finished units before leaving the factory. This quality control reflects our high standards,
which not only exceed market requirements but also take them
several steps further.
Modulating bypass
An automatic bypass valve directs the fresh air past
the heat exchanger when waste heat recovery is not
necessary, thus conserving energy.
Automatic control
The Comfort 1200 is supplied with an integrated CTS 602
control, which is operated by the enclosed control panel.
The modern CTS 602 control communicates Modbus
RTU RS485. A CTS system using this type of
communication can easily be connected to the device.
Filters
The Comfort 1200 is supplied with bag filters. An M5
filter in the air exhaust and an F7 filter for fresh air are
supplied as standard.
The CTS 602 control has a built-in timer controlled
alarm for change of filter. It is possible to install a pressure controlled filter monitor (accessorie).
Doors
The large doors allow easy access for the changing
the filters, as well as for servicing of the unit.
Frost protection
An electric heater can be purchased for frost protection.
This prevents the formation of ice in the counterflow
heat exchanger in the event of long periods of frost.

COMFORT 1200 BY NILAN
Counterflow heat exchanger
Heat recovery is achieved by two counter flow heat
exchangers made of highly corrosion resistant marine aluminium. The counterflow heat exchangers have an energy
efficiency of more than 80% and prevent odours being
transferred from the extracted air to the supply air.
The CTS 602 control allows for cooling recovery.
Plug fans
The two fan sections consist of energy-efficient EC motors
with built-in motor controllers operated by a 0-10V signal.
The efficient fan wheels haverear facing impellers and are
extremely quiet.
Construction
The Comfort 1200 is housed in a strong frame structure
of Aluzinc with 50 mm insulation.
Base
The Comfort 1200 is delivered with a robust, built-in base.
Heating elements
External water or electric heating elements, regulated
by the CTS 602 control, can be purchased.
Pressure control
The extraction and/or supply fan can be operated
with the aid of a pressure transmitter.
The water-heating surface can be built into the unit.

AUTOMATION
CTS602 Control
The Comfort 1200 is controlled using its 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 location, 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.
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
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.
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.

Operation Ice building
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 hand, if
the ventilation is for an office, it may be acceptable to decrease
the operating level at night.

ACCESSORIES
Top cover
If Comfort 1200 is going to be installed outside, it is possible to order a top cover which
protects the unit against rain and snow.
Pressure transmitter
The extraction and/or supply fan can be operated with the aid of one or two pressure
transmitters.
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 unit 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.
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).
Installationset
Vibration absorbers and a water trap for the condensation outlet.
Heating cable
To protect the condensation outlet against frost, a 3 metre-long self-regulating
heating cable can be ordered.

During installation, future service and maintenance should be
taken into account. We recommend a minimum gap in front of
and behind the unit of 96 cm.
Service clearance
(unit shown from above)
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.
The electric heating element must be connected by an authorised electrician.
