How to use this guide
This guide is divided into two parts:
• Daily Use (Turn the guide over)
Yellow sections 01 - 09
• Installation and maintenance:
Grey sections 10 and onwards
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
Installers 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.

Note!
System diagrams in this instruction are principal drawings and
do not contain all components which are necessary in heating
systems.
Identifying the system type
10
In this section you find the most frequently used systems. If
your system is not quite as shown below, find the diagram
which has the best resemblance to your system and make
your own combinations.
Check the setting of line 24 in circuit I (gear motor / thermo
actuator).
Heating system type 1
Indirectly connected heating circuit and PI-regulated hot
water service circuit
Heating system type 2
Directly connected heating circuit and indirectly connected
PI-regulated hot water service circuit
Check the setting of line 24 in circuit I (gear motor / thermo
actuator).
Alternatives using the same settings:
Heat exchanger or direct district heating
Installation
Installation
Mounting the ECL Comfort
controller
11
For easy access, you should mount the ECL Comfort
controller near the heating unit. Select one of the three
following methods:
Mounting on a wall
Mounting on a DIN rail
Mounting in a panel
Screws and rawlplugs are not supplied.
Mounting on a wall
Socket for mounting on wall: Order code No. 087B1149.
Mount the terminal box on a wall with a smooth surface.
Establish the electrical connections and position the
controller in the box. Secure the controller with the fixing
screw.
Mounting on a DIN rail
Mounting kit: Order code No. 087B1145.
A mounting kit is necessary to mount the box with the
controller on a DIN rail.
Mounting in a panel
Connector set: Order code No. 087B1148.
The panel plate thickness must not exceed 3 mm.
Prepare a cut-out with the dimensions 92 x 138 mm. Pull off
the right side of the lid by means of a screwdriver.
Insert the controller into the panel cut-out and fix it with the
two locks which are placed diagonally in two corners of the
controller.

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:
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.
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.
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.

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 installers 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

The max. influence determines how much the
room temperature should influence the flow
temperature.
The grey side of the ECL Card.
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.
Go to line 3.

When the actual flow temperature is within the
neutral zone, the controller does not activate the

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.

A low integration time constant will make the
controller react fast but with less stability.

Set the neutral zone to a high value if you can
accept a large variation in flow temperature.
When the actual flow temperature lies within the
neutral zone, the controller does not
activate the motorized valve.

Check list
Is the ECL Comfort controller ready for use?
Make sure that the power supply is connected to
terminals 1 (Live) and 2 (Neutral).
See section 12 or 13.
Check that valves and pumps are connected to
the correct terminals.
See section 12 or 13.
Check that all sensors are connected to the
correct terminals.
Mount the controller, and switch on the power.
Insert the ECL Card with the yellow side facing
you, and push
, if necessary.
See section 15.
Select manual operation in the controller mode.
See section 2 in the users guide.
Check that valves open and close, and that
pumps start and stop when operated manually.
See section 19.
Check that the temperatures shown in display A
and B match the actual sensors, both for circuit
I (heating) and circuit II (hot water).
See section 1 in the users guide.
If your heating system differs from the diagram
shown on the overleaf of the cover, you should
check and perhaps alter the service parameters.
Please pay special attention to line 35 and 36.
