MAKING MODERN LIVING POSSIBLE
One Product – Numerous Applications
Electronic Controllers for Heating, Cooling,
Ventilation and Air Condition
Electronic Controllers from Danfoss:
Only a Few Products for an Endless Number
of Applications
The ECL Comfort and ECL Apex 10
product ranges consist of electronic
controllers for temperature control in
heating and domestic hot water (DHW)
systems. The controllers ensure a high
comfort level and optimum energy
utilization.
The components of ECL Comfort
The ECL Comfort range consists of ECL
Comfort 100, 200 and 300 – each in an
elegant and timeless design.
ECL Comfort 100 is the choice for
simple heating systems, for which the
installer or user prefers the traditional,
plain and analog operation.
ECL Comfort 200 appeals to users
who prefer a digital user interface
and the increased number of options
this provide. The series offers many
functional options and can be used
for commercial installations.
ECL Comfort 300 is the advanced
controller with a large number of
functions, such as: Two control circuits
+ thermostatic function, optimizer
function, 3 point control, LON
communication etc. The intelligent
card concept ensures optimum
user-friendliness of this advanced
controller.
2
The range also comprises an elegantly
designed remote control in two
versions, which is connected to the
controller via a two-wire cable.
ECL Comfort
– The future is in the Cards
The ECL Comfort range and its
advanced chip card not only meet
your present demands but also the
future requirements you might have
for heating control.
With ECL Comfort 300 new demands
are covered by new cards with new
settings. The few basic models and
the large variety of ECL Cards give you
a considerably better and quicker
overview of the unique application
opportunities offered by the ECL
Comfort range.
Some advantages of ECL Comfort:
Optimizer and boost function
Return temperature limitation
based on outdoor temperature
Frost protection
Heating cut–out function
Year clock and automatic changeover between summer and winter
time
Copy function to/from the
intelligent ECL Card
Anti-bacteria function (DHW circuit)
Communication via the
standardized LonTalk Protocol,
RS 232, and M-bus options
By means of the chosen card, it is easy
to set the controller and simple to
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. This
is environmentally sound and saves
money.

Flexibility and Easy Operation
Auto tuning and motor protection
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 benefits:
A high degree of comfort
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 simple and
reliable procedure. Auto tuning is
especially necessary in DHW systems.
Improved protection against lime
deposits in DHW heat exchangers
All applications, updates and other
information are placed on the Danfoss
Heating Portal from where it can be
downloaded.
Remote service possibilities with
WebAccess
The WebAccess makes your ECL
Comfort 200 and 300 accessible via
Internet or modem.
Energy saving
Long operating life
Minimum service
You can define different levels of access
going from monitoring to wide control
of parameters in the ECL controller.
Some advantages of the
ECL Apex 10:
Temperature, pressure and
flow control
The WebAccess is used in a LON network – communicating with up to
4 ECL controllers. Other components
such as energy meters can also be
monitored via the WebAccess.
Data logging facilities
Alarm functions associated to
either system, application or
monitoring failures
ECL Apex 10 – configurable controller
The ECL Apex 10 is a dedicated district
heating controller preprogrammed
with all relevant control functions and
applications. The controller is applicable
in large substations and distributor
stations and can be connected as stand
alone or in network.
Easy and cost-effective
commissioning and service;
a variety of application templates
are ready for use
