Electronic controllers from Danfoss:
Only a few products for an
endless number of applications
Based on the success and benets
of previous generations, the Danfoss
ECL Comfort 210, 296 and 310 controllers ensure comfort and convenience
for heating, cooling and domestic hot
water systems.
The components of ECL Comfort
The ECL Comfort range consists of ECL
Comfort 110, 210, 296 and 310 – each
in an elegant and timeless Scandinavian design.
ECL Comfort 110 is the choice for ba-
sic heating systems, for which the installer or user prefer a traditional operation.
ECL Comfort 210 appeals to users
who prefer an increased number of
options. The series oers many functional options and can be used for
commercial installations. Two control
circuits + thermostatic function, optimizer function, 3-point control of actuators, Modbus communication for
smaller SCADA systems etc.
ECL Comfort 296 covers the same as
ECL Comfort 210 and has in addition
M-bus and Ethernet connections. Furthermore, ECL 296 has the popular
size, 144 x 96 mm.
ECL Comfort 310 is the advanced con-
troller with a large number of functions, such as: Three control circuits
+ thermostatic function, optimizer
function, 3-point control of actuators,
Modbus/M-bus/Ethernet communication etc.
The intelligent key concept for ECL
Comfort 210 / 296 / 310 ensures optimum user-friendliness of these advanced controllers.
The ECL Comfort range also comprises
an elegantly designed remote control
in two versions, which can access all
parameters in the controller.
The future is in the keys
The ECL Comfort range and its advanced software key not only meet
your present demands but also the future requirements you might have for
heating control.
With ECL Comfort 210 / 296 / 310 new
demands are covered by new keys
with new settings. The few basic models and the large variety of ECL keys
give you a considerably better and
quicker overview of the unique application opportunities oered by the
ECL Comfort range. Menus are available in multiple languages.
By means of the chosen key, it is easy
to set the controller and change the
factory settings precisely to the relevant type of system and required settings.
The schedule in the ECL Comfort can
be programmed for each day in the
week. The building will be heated in
the comfort periods you request; also
holidays can be scheduled on beforehand. This is environmentally sound
and saves money.

Automatic setup of DHW parameters
A precondition for a well functioning heating system is that the correct settings
are made before it is put to use. Adjustments are necessary to preset the control
parameters.
Presetting gives the following benets:
A high degree of comfort
Improved protection against lime deposits in DHW heat exchangers
Energy saving
Long operating life
Minimum service
The introduction of automatic setting of control parameters on the controller
itself, i.e. auto tuning and motor protection, gives optimum control of the DHW
system. This ensures a high degree of comfort, stable control during idle operation and, subsequently, longer motor life.
The setting of control parameters can thus be reduced to one easy and reliable
procedure. Auto tuning is especially necessary in DHW systems.

Intelligent communication solutions
Our solutions are wide-ranging – in
every respect. We cover almost every
area of application. From busy cities
and suburbs to idyllic villages – as well
as from public or commercial buildings to residential homes.
Intelligent solutions
– intelligent communication
Danfoss communication solutions provide the ultimate in control. We don’t
just supply controllers, but unique
software which facilitates remote
monitoring and control of district heating systems. Our oering ranges from
standard software fully integratable
with the existing plant and buildings,
to complete systems with full support.
There are many good reasons to
choose a solution which allows you to
monitor, control – and therefore service – your system remotely, regardless
of whether the system services buildings in urban areas or rural communities. Danfoss has – and will supply – an
advantageous solution for you.
Your future communication platform
Remote monitoring and communication is the future as of today. Our solutions cover traditional forms of district
heating and alternatives, such as biomass plants. A Danfoss platform will
provide better, and simplied control
over a system, which not only optimizes the control processes, but also
yields savings and protects the environment. In some networks you have
large pumps and large controllers
leading to substantial energy usage.
Here it is important with an optimized
district heating network. An electronic
controller will not only simplify plant
management, it will also save energy.
Act proactive to service
Danfoss communication solutions enable you to act pro-actively to provide
better service. Thanks to ecient monitoring and alarm systems, they can
isolate and remedy problems – even
before the customer knows they exist.
For example; if the ow temperature is
incorrect, the system will automatically
activate an alarm, to warn about excessive energy consumption.
For optimum control in any system
Your requirements have been combined with our know-how to extend and
innovate our product range. Danfoss markets a comprehensive range of motorized control valves with features that give an optimum t with the ECL Comfort
controller. Our control valves are available in multiple sizes, dierent materials
and with a variety of connections. The range of motorized control valves meet
the requirements in any of these applications:
Terminal and zone
Heating and cooling

ENERGY SAVING AND
COMFORT IS A MATTER OF
OPTIMUM ENERGY CONTROL
When you look at urban and rural areas with varying housing densities,
the selection of heat sources for each
individual building will dier. Where
available, district heating will most often be a part of the solution. District
heating benets the individual homeowner or tenant as well as the society
at large. Where district heating is not
available, individual solutions will be
used – preferably in combination with
renewable energy sources.
One of the solutions for achieving energy savings in any building is the use
6

of electronic controllers for weather
compensation. By letting the ow in
the heating system of the house reect outdoor temperatures, optimum
operation and performance of the
heating installation is obtained.
In a recently published COWI report,
the advantages of weather compensation are sound and clear: In one
family houses, the expected energy
saving is on average 10% – and in
some cases up to 40%.
What role does the ECL Comfort play?
The ECL Comfort is an electronic controller for weather compensation. By
tting typical applications for district
heating, cooling and micro network
systems including communication,
it enables you easily to optimize system performance and operation. This
leads to energy savings and longer
system life.
A correctly installed and commissioned electronic controller is the
prerequisite for a stable and wellfunctioning heating system. Easy installation and an intuitive interface
makes sure that the ECL Comfort controller is always installed correctly for
the maximum benet.

cation in the ECL controller, all without any need for advanced programming. This makes it easy to manage
and adjust your application settings.
In the event of malfunction in the
heating system the application parameters won't be aected by e.g.
power failure since they are stored in
the controller. Besides the data log-
ging facility in the ECL controller facilitates troubleshooting and keeps
system maintenance at a minimum.
The Application Key also facilitates
copying of settings to other ECL controllers in the system. This makes it
easy to adjust settings and helps ensure smooth operation and energy
optimisation for years to come.
