How to use this guide
This guide is divided into two parts:
• Daily Use (turn the guide over)
Yellow sections 1-7
• 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 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 diagram 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 guides 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 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 are used in
connection with optional modules, and you can find a
description of the settings and the corresponding
parameters in the instruction for optional module in
question.
Operating the ECL controller and the ECL Card
The ECL Card has a yellow side for the daily use and a
grey side for the installation and maintenance.
Both sides of the card are divided into lines representing
the different options of control and programming.
Select the side of the ECL Card you want to
operate.
The light diode below the inserted ECL Card
indicates the chosen side, ie. left light for daily use
and right light for the installation and maintenance.
(See sections 15 and 16).

Mounting the ECL Comfort
controller
11a
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 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.
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.

Adapting the ECL Comfort
controller
While the set-up is in operation, the data transfer-display
will appear.
After initialising, the display will return to the standard
display line C of the yellow side of the ECL Card.
The controller is now ready to control the selected
heating system. You can make your own adjustments/
settings for daily use in the basic set-up and change the
extended service settings.
Open the lid and switch on the controller. The display
shows the heating system type.

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 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.
Boiler sensor
(ESMU, ESM-11 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, ESM-11 or ESMC types)
The return sensor should always be placed in/on a pipe
with return water flow.
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 nor
close to radiators, windows or doors.
Insert the ECL Card with the grey side facing you.
See section 16 for general principles of operation and
section 17 for setting the time and date.
Select the grey side of the ECL Card for the
basic set-up and the extended service
parameters.

permanent ink pen.
Changing from one side of the ECL Card to the other
When changing from the grey side of the ECL Card to the
yellow side, you will always enter line C and the standard
display.
Changing from the yellow side to the grey side, you will
always enter line A - Time and date.
See opposite page.
General principles
When the controller is connected and operating you can
check and adjust all or some of the basic settings
referring to the grey side of the ECL Card. Select the grey
side of the ECL Card.
Use the arrow buttons to move from line to line
of the ECL Card, for example line 2:
Use the minus/plus buttons to adjust the
setting(s).
In some displays more than one setting or
value can be adjusted. Use the shift button to
switch between the options. The chosen value
flashes in the range indicator.

ROOM
Max. limitation
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.

The adaptive function will eliminate the difference between
the required and actual room temperature by integrating
the difference and adjusting the reference for the flow
temperature.

OFF: The adaptive function is cancelled.
1: The desired temperature is adapted
quickly.
30: The desired temperature is adapted
slowly.
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
optimisation period is over or the room temperature has
been reached.

When the boiler is heated up from a temperature below
the set minimum limit, ie. the shift from reduced temperature
to comfort temperature, the heating up period must be as
short as possible to reduce the time of possible
condensation in the furnace.
This prevention is obtained by allowing the smallest
possible removal of heat from the boiler (the circulation
pump is stopped).
When the minimum temperature limit +4 K is reached, the
circulation pump starts again. If the temperature decreases
below the minimum temperature, the pump is stopped
again.
These conditions apply for high thermic capacity boilers.

The circulation pump can be stopped to prevent condensation
in the boiler during heating up.

The boiler circuit pump can be stopped at certain
conditions during comfort and reduced temperature
periods.
ON: The circulation pump is controlled
according to extended conditions;
• Pump is OFF when Troom. is > Troom.set
+ 1K and Tref. < Tmin. This means that
the room temperature will not be too
high even if Tref. is limited by the
minimum setting of the boiler circuit.
OFF: The circulation pump is controlled
according to normal conditions.
Normally the boiler circuit pump is ON when the boiler
temperature is >20 °C or the outdoor temperature is <2 °C.
