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 the 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.

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.
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 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.

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:
Room temperature sensor
(ESMR, 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 nor
close to radiators, windows or doors.
Boiler sensor
(ESMU, ESMA or ESMC types)
Place the sensor according to the boiler manufacturer’s
specification.
Do not move the sensor after it has been fastened in
order to avoid damage to the sensor element.
Return temperature sensor
(ESMU, ESMA or ESMC types)
The return sensor should always be placed in/on a pipe
with return water flow.
Hot water temperature sensor
(ESMU or ESMB types)
Place the hot water sensor according to the
manufacturer’s specification.
Outdoor temperature sensor
(ESMT type)
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.

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 the heating system type from the ECL Card. After
copying, the display will show the heating system type the
controller is set up to control. After approx. 10 sec. the dis-
play will change to display line C.
The controller is now ready to be set to control your
heating system.

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.

ROOM
This section is only relevant if you have installed a room
sensor. There are two basic principles for control of the
room temperature influence:
The max. influence determines how much the
room temperature should influence the flow
temperature.
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.

The lower the outdoor temperature the less
the temperature reduction. When the outdoor

Adjusting the service
parameters
In addition to the settings in line 1 to 7 on the grey side
of the ECL card, there is an extended service menu
from line 10 and onwards.
When you have entered all your personal settings, turn
the ECL Card over so that the yellow side faces you.
If you want to copy the new settings to the ECL Card
(recommended by Danfoss), see section 34 “Copying
data with the ECL Card”.
Make a note of your new settings on the parameter list
in section 31.
Push repeatedly to reach the lines
numbered 10 and onwards.
Now you can move to any line of your choice.
Set the parameter value.
You can select any of the two circuits no
matter what line you are in. You will not
necessarily enter the same line number.

Service parameter 12
In order to shorten the heating-up period after a reduced
temperature period, the flow temperature can be increased
temporarily.
If a room sensor is installed the boost stops when the
optimising period is over or the room temperature has
been reached.
Shortens the heating-up period by increasing the flow tempera-
ture by the percentage you set.

Set the percentage at which you want the flow
temperature to be changed temporarily.
The adaptive function will eliminate the difference
between the required and the actual room temperature by
integrating the difference and adjusting the reference for
the flow temperature.
Dimensioning temperature: The lowest outdoor
temperature at which the heating system can obtain
the desired temperature.
OFF: The adaptive function is cancelled.
1 : The desired temperature is adapted
quickly.
30 : The desired temperature is adapted
slowly.
Controls how fast the room temperature adapts to the
desired temperature.

OFF: No optimisation. The heating starts and stops at
the times set in the week plan.

Adjust the optimising time constant. The value
consists of a number of two digits. You can select
the following values:
11, 12, ..... 59.

Select total stop function.
ON: Total stop function is ON. At total stop the
flow temperature reference is lowered to
10°C, and the minimum setting of the flow
temperature limit of line 2 (see section
22) is overruled in the reduced
temperature period.
OFF: No total stop

This function is used if circuit I is the main supply for toher
mixing circuits.
The temperature reference in heating circuit I can be influenced by
another external. The set number determines the influence of the
flow temperature reference in circuit I or the reference signal by
any other connected controller.
