Save energy - save money - improve your comfort
temperature
The ECL Comfort controller is designed by Danfoss for
temperature control of heating and hot water 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.

Optional
Make sure that the surface of the pipe is clean at the area
where the sensor is mounted.
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.
14
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
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 flow outlet.

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
should 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 heating system
you can write a title on the ECL Card with a permanent
ink pen.
15a
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.

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 min. influence and a
negative value for max. influence.
This section is only relevant if you have installed a room
sensor or ECA 60/61. 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.
The bar below the range indicator flashes in the
right side of the display.
Adjust 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 small integration 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.
Basic set-up
Basic set-up
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.

The controller with the ECL Card C37 can control the hot
water temperature with either one or two sensor(s). The
controller will automatically register the number of
sensors.
Select circuit II
Note!
If only one sensor is mounted, the hot water temperature
difference is equal to the cut-out temperature minus the
cut-in temperature.
Example: 45 °C minus 40 °C = 5 K
