Save energy - save money - improve your comfort
temperature
The ECL Comfort controller series is designed by Danfoss
for temperature control of heating, hot-water and cooling
systems.
The ECL Comfort controller ensures you of the following;
• Room, hot-water, or cooling temperatures will be
adjusted to your personal settings.
• Lower temperatures and lower energy consumption
reduce costs and ensure optimum use of energy
resources.
Sketch your application
The ECL Comfort controller series is designed for a wide
range of heating, hot-water, and cooling systems with
different configurations and capacities.
If your system differs from the diagrams shown in section
10, you may want to make a sketch 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 that
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 could be related either
to recent updates or the use of optional modules (which are
described in the instructions in question).
How to use this guide

* The system device bus/room panel/remote control is only active

It is important that the sensors are mounted in the correct
position in your system.
The temperature sensor mentioned below are sensors
used for the ECL Comfort 200 and 300 series which not all
will be needed for your application.
Outdoor temperature sensor (ESM-10)
The outdoor sensor should be mounted on that side of the
building where it is less likely to be exposed to direct
sunshine. It should not be placed close to doors, windows
or air outlets.
Flow temperature sensor (ESMU, ESM-11 or ESMC)
Place the sensor max. 15 cm from the mixing point. In
systems with heat exchanger, Danfoss recommends that
the ESMU type to be inserted into the exchanger flow
outlet.
Make sure that the surface of the pipe is clean where the
sensor is mounted.
Return temperature sensor (ESMU, ESM-11 or ESMC)
The return sensor should always be placed in / on a pipe
with return water flow.
Room panel ECA 60 or remote control ECA 61
Do not place it on outside walls or close to radiators,
windows or doors.
Hot-water temperature sensor (ESMU or ESMB)
Place the hot water sensor according to the
manufacturer’s specification.
Boiler sensor (ESMU, ESM-11 or ESMC)
Place the sensor according to the boiler manufacturer’s
specification.
Flow/air duct temperature sensor
Place the sensor close to the exchanger.
Installation
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.

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.

General principles
When the controller is connected and operating you can
check and adjust all or some of the basic settings on the
grey side of the ECL Card (see the example below).
Use the arrow buttons to move from line to line
of the ECL Card, for example line 2:

In some displays more than one setting or value
can be adjusted. Use the shift button to switch

The circuit selector shifts between circuit I
and II. You can adjust all settings and service
parameters individually in both circuits, ie.
circuit II.

Floor heating systems
This controller is factory set for radiator systems, which are
typically high flow temperature systems.
To control floor heating systems, which are typically low flow
temperature systems, you need to change the heat curve
according to your type of system.

Whether it is reasonable to change the slope or parallel
displacement will depend on the individual heat requirement.
If the requested heating temperature can only be reached in
the long run by a noticable parallel displacement (+) of the
set slope, the slope should be changed.
Small increases or reductions in heating temperature can be
implemented by means of the parallel displacement.

Basic set-up
The room sensor in the reference room
registers the difference between the desired
and the actual room temperature. The flow
temperature reference will be corrected to
eliminate this difference.
B: Reference room 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 min. influence and a
negative value for max. influence.
Example 1
The actual room temperature is 2
o
C too low.
The influence at max. limitation (right corner of the display) is
set to
-20.
The influence at min. limitation (left corner of the display) is
set to 20.
Heat curve H is 1.8.
Result:
The flow temperature reference is changed by

Example 2

Note!
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.

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.

indicator
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.
