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 different configurations and
capacities.
If your heating system differs 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 final adjustments before the end-user takes
over.
Note! 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 find a
description of the settings and the corresponding
parameters in the instruction for the optional module in
question.

Placing the temperature
sensors
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
(ESM-10 type)
The outdoor sensor should be mounted on the north side
of the building where it is less likely to be exposed to di-
rect 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 flow 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 flow never stops.
Room temperature sensor
(ESM-10, 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.

Understanding the ECL Card
The ECL Card contains factory settings for a standard
heating system. If the actual heating system differs 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 ECL 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 heating system
you can write a title on the ECL Card with a permanent
ink pen.

Inserting the ECL Card
How to insert your ECL Card the first 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.

This section is only relevant if you have installed a room
sensor. There are two basic principles for control of the
room temperature influence:
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
fire place, etc.
The max. influence determines how much the
room temperature should influence the flow
temperature.
Go to line 3.
Select the max. influence.

Set the proportional band.
A higher value will result in a stable, but slow
regulation of the flow temperature.
Go to line 5.
Set a high integration time constant to obtain a
slow but stable reaction to deviations.
A low integration time constant will make the
controller react fast but with less stability.
Go to line 6.
Set the running time of the motorized valve
according to the example on the opposite page.
This is the time it takes the valve to move from
closed to fully open position.
Go to line 7.
Set the neutral zone to a high value if you can
accept a high variation in flow temperature.
When the actual flow temperature is within the
neutral zone, the controller does not activate the
motorized valve.
Note! The valve is symmetrical around the
flow reference value.
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.
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 %.
Note! Make sure there is a consumption when you set the
parameters.

How to calculate the running time of the motorized valve
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.

Auto Tuning
The Auto Tuning function automatically determines the PI-
control parameters for domestic hot water control. Thus you
do not need to set the parameter lines 4, 5, 6, and 7 in
circuit II, as they are automatically set to the Auto Tuning
function.
Auto Tuning is typically used in connection with the
installation of the controller, but it can be activated when
needed, e.g. for an extra check of the control parameters.
Before starting the Auto Tuning, the tapping flow should be
adjusted to the relevant value (see table below).
If possible, any additional hot water consumption should
be avoided during the Auto Tuning process. Should the
tapping load vary too much, the Auto Tuning and controller
will return to the default settings.
Auto Tuning is set to ON/OFF by using the service
parameter line 173 in circuit II, press
(ON) and
(OFF). When the Auto Tuning is ended, the service
parameter is automatically set to OFF (default setting). This
will be indicated in the display.
Typically, the Auto Tuning process takes 7-14 minutes but
can sometimes take up to 25 minutes.
Important!
In order to meet the summer-/winter variations, the ECL
clock must be set to the correct date for an successful Auto
Tuning. The motor protection function (line 174) has to be
deactivated during Auto Tuning.
During tuning the circulation pump for tap water service
must be turned off. This is done automatically if the pump is
controlled by the ECL controller.
