Save energy - save money - improve your comfort
temperature
The ECL Comfort controller is designed by Danfoss for
temperature control of heating systems.
The ECL Comfort controller ensures you of the following;
• Room and hot water temperatures will be adjusted to your
personal settings.
• Lower temperatures and lower energy consumption
reduce costs and ensure optimum use of energy
resources.
• The automatic pump motion program protects the
circulation pump against blocking.
Sketch an outline of your heating system
The ECL Comfort controller is designed for a wide range of
heating systems with diff erent confi gurations and
capacities.
If your heating system diff ers from the diagrams shown in
section 10, you may want to sketch an outline of the
system about to be installed. This makes it easier to use the
Installer’s Guide, which will guide you step-by-step from
installation to fi nal adjustments before the end-user takes
over.
The controller is pre-programmed with factory
settings which are shown in the relevant sections of this guide.
However, you might come across some settings that
are not listed in this instruction. These settings are used in
connection with optional modules, and you can fi nd a description
of the settings and the corresponding parameters in the
instruction for the optional module in question.
How to use this guide

Installation
Installation
It is important that the sensors are mounted in the correct
position in your heating system.
Special attention should be paid to the following sensors:
Outdoor temperature sensor
(ESMT type)
The outdoor sensor should be mounted on the north side
of the building where it is less likely to be exposed to direct
sunshine. It should not be placed close to doors or windows.
Flow temperature sensor
(ESMU, ESM-11 or ESMC types)
Place the sensor max. 15 cm from the mixing point. In
systems with heat exchanger, Danfoss recommends the
ESMU-type to be inserted into the exchanger fl ow outlet.
Make sure that the surface of the pipe is clean at the area
where the sensor is mounted.
Do not move the sensor after it has been fastened in
order to avoid damage to the sensor element.
Return temperature sensor
(ESMU, ESM-11 or ESMC types)
The return sensor should always be placed max. 15 cm from
the mixing point. It should always be placed on a pipe in
which the water fl ow never stops.
Room temperature sensor
(ECA 60 and 61 remote control)
Place the room sensor in the room where the temperature is
to be controlled. Do not place it on outside walls or close to
radiators, windows or doors.

How to insert your ECL Card the fi rst time
After the power has been switched on, open the lid on the
front side of the controller.
Place the ECL Card with the yellow side facing you. This
enables the controller to read the ECL Card data.
The controller immediately starts to copy the factory
settings and heating system type from the ECL Card. After
copying, the display will show the heating system type the
controller is set to control. After approx. 10 sec. the display
will change to display line C.

The controller is now ready to be set to control your heating
system.
Inserting the ECL Card
15a
Understanding the ECL Card
The ECL Card contains factory settings for a standard
heating system. If the actual heating system diff ers from the
standard system, the controller must be adjusted
accordingly. After the adjustment, the new settings can be
stored on the ECL Card.
For ECL Card copying and daily use including
adjustment of temperatures and time periods, insert the
ECL Card with the yellow side facing you.
For system set-up adjustments, the grey side of the ECL
Card - the installer’s side - must be facing you.
As a main rule, the ECL Card should always remain in the
controller during service, maintenance and settings.
If the card is removed please note that:
• The controller settings are locked after approx. 10 min.
• The ECL Card must not be exposed to direct heat or
sunshine
If several controllers are installed in the system you can
write a title on the ECL Card with a permanent ink pen.

This section is only relevant if you have installed ECA 60 / ECA 61
/ ECA 62 / ECA 63. There are two basic principles for control of the
room temperature infl uence:
A: Max. room temperature limitation
Use this limitation if your heating system is fully equipped
with radiator thermostats and you also want to obtain a max.
limitation of the room temperature. The controller will allow
for free heat gains, i.e. solar radiation or heat from a fi re place,
etc.

The max. infl uence determines how much the room
temperature should infl uence the desired fl ow temperature.
Example
The actual room temperature is 2 degrees too high.
The infl uence at max. limitation (right corner of the display) is
set to -40.
The infl uence at min. limitation (left corner of the display) is set
to 0.
Heat curve H is 1.8.
Result:
The desired fl ow temperature is changed by
2 x -40 x 1.8 x 0.1= -14.4 degrees.

B: Reference room temperature control
Used if your heating system is not equipped with radiator
thermostats and you select the room with room sensor as a
temperature reference for the rest of the rooms.
(However, should you have a few radiator thermostats
installed, make sure that they are fully open).
Set a positive value for the min. infl uence and a
negative value for the max. infl uence.
The room sensor in the reference room registers
the diff erence between the desired and the actual
room temperature. The desired fl ow temperature
will be corrected to eliminate this diff erence.
Example 1
The actual room temperature is 2 degrees too low.
The infl uence at max. limitation (right corner of the display) is
set to -35.
The infl uence at min. limitation (left corner of the display) is set
to 20.
Heat curve H is 1.8.
Result:
The desired fl ow temperature is changed by
2 x 20 x 1.8 x 0.1= 7.2 degrees.
Example 2
The actual room temperature is 2 degrees too high.
The infl uence at max. limitation (right corner of the display) is
set to -35.
The infl uence at min. limitation (left corner of the display) is set

Setting the PI regulation -
lines 4-7
26a
If you want to tune the PI regulation precisely, you
can use the following method:
• Set the integration time (line 5) to its max. value (999 sec.).
• Decrease the value for the proportional band (line 4) until the
system starts hunting with a constant amplitude (it might be
necessary to force the system by setting an extreme value).
• Find the critical time period on the temperature recording or
use a stop watch.
Temperature
Critical time period
Critical time period
Critical time period
Critical time period
Time
Time
This time period will be characteristic for the system, and you can
evaluate the settings from this critical period.
Integration time = 0.85 x critical time period
Proportional band = 2.2 x proportional band value in the
critical time period.
If the regulation seems to be too slow, you can decrease the
proportional band value by 10%.
Make sure there is a consumption when you set the parameters.

The running time of the motorized valve is calculated using the
following methods:
Seated valves
Running time = Valve stroke (mm) x actuator speed (sec. / mm)
Example: 5.0 mm x 15 sec. / mm = 75 sec.
Rotating valves
Running time = Turning degrees x actuator speed (sec. / degr.)
Example: 90 degrees x 2 = 180 sec.

-29 to +10 °C:
The setting of reduced temperature depends
on the outdoor temperature, when the outdoor
temperature is higher than the set limit.
The lower the outdoor temperature the less the
temperature reduction. When the outdoor
temperature is below the set limit, there is no
temperature reduction.

Set the percentage at which you want the fl ow
temperature increased temporarily.
In order to shorten the heating-up period after a reduced
temperature period, the fl ow temperature can be increased
temporarily.
If a room temperature sensor is installed, the boost stops
when the optimising period is over or the room temperature
has been reached.

Set the opening time you want the valve to use.
In order to avoid load peaks in the supply network, the fl ow
temperature reference can be set to increase slowly after a
period with reduced temperature. This causes the valve to
open slowly.
