User’s Guide
Before you start
Save energy - save money - improve your
comfort temperature
The ECL Comfort controller is designed by Danfoss for the
automatic temperature control of heating sys tems.
The advantages of the ECL Comfort controller system are
the security of your heating control and the op ti mum use
of energy resources.
Seasonal changes and variations in outdoor temperatures
are mon i tored by the control system.
Decreased temperatures and low energy consumption
while you are out or asleep save heating costs.
The temperature programming provides comfort and
the au to mat ic pump motion program protects against
blocking.
Time control of the ECL Comfort 100M controller
When an analog clock is mounted the controller can
reduce or increase the room temperature automatically.
This ensures comfortable temperatures when you are at
home and helps you save energy and thus reduce costs
while you are out.

Clock (optional)
A clock can be mounted when an automatic change between
comfort temperature and reduced temperature is desired.
Setting the clock
Turn the minute hand to set the actual week day (7-day clock)
and time.
Note!
You will move the entire outer ring of the clock with its sliders,
just by turn ing the minute hand. Turn the minute hand until
the white ar row points at the actual week day and hour in the
outer ring.
Note!
Do not turn anti-clockwise, as this may damage the clock.
Summer time setting
Remember to set summer- and wintertime +/- 1 hour.
Individual comfort and reduced
tem per a ture periods
Determine in which periods of time you want comfort
temperature or reduced temperature. Look at the week
days and hours written in the outer ring of the clock. You
can choose heating at comfort temperature by set ting the
slid ers in the outer ring to point towards the cen ter. If you set
the slid ers to point outwards, you set the heat ing sys tem to
re duce temperature at the cor re spond ing pe ri od of time.

Adjustments
• With room sensor.
If the wanted comfort temperature is not reached?
Make sure that the radiator thermostat/valve is fully open in the
room with the room sensor.
• Without room sensor.
The rooms seem to be too cold?
Before adjusting the comfort temperature on the controller it
is advisable to check and perhaps adjust the settings of your
radiator thermostats/valves.
If you are not able to obtain the desired temperature by these
adjustments, the fl ow temperature is too low. Increase the
value.
See also page 12: Setting the heat curve.
Temperature setting without room sensor
(parallel displacement of the heat curve)
If you have no room sensor installed, your system will not
know the exact room temperature. Therefore you can only
use the temperature setting button to change the fl ow
temperature. This cor re sponds approx. to a possible change
in room temperature of +/- 8 °C.
Temperature setting with room sensor
If you have a room sensor installed, the midpoint of the
temperature setting button will correspond to a room
temperature of 20 °C. The room temperature can be set in a
range from 12 to 28 °C.

Save energy - save money - improve your
comfort temperature
The ECL Comfort controller is designed by Danfoss for
tem per a ture con trol of heating systems.
The ECL Comfort ensures you of the following;
• Room temperatures will be ad just ed to your personal
set tings.
• 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.

of system compositions.
If your system is not quite as the diagrams of the most
frequently used systems, fi nd the diagram with the best
resemblance with your system and make your own
combinations.

You should mount the ECL Comfort controller for easy
access near the heating unit. You can choose between three
methods:
• Mounting in a panel
• Mounting on a wall
• Mounting on a DIN rail
Screws and rawlplugs are not supplied with this pack age.
Mounting the controller
Mounting in a panel
Order mounting kit No. 087B1148.
The panel plate thickness must not exceed 3 mm. Prepare
a cutout measuring 92 x 138 mm. Establish the electrical
con nec tions. Insert the controller into the panel cutout and
fi x it with the two locks which are placed diagonally in the
two corners of the controller.
Mounting on a wall
Order mounting kit No. 087B1154.
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 by the fi xing screw.
Mounting on a DIN rail
Order mounting kit No. 087B1145.
A mounting kit is necessary to mount the box with the
controller on a DIN rail.

It is important that the sensors are mounted in the correct
position in your heating system.
Outdoor temperature sensor
(ESMT type)
The outdoor sensor should be mounted on the north side
of the building where it is less likely to be exposed to direct
sun shine. 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 fl ow outlet. Make sure
that the surface of the pipe is clean where the sen sor is to be
mounted.
Placing the tem per a ture sensor types
Room temperature sensor
(ESM-10, ECA 60 and 61 remote controls)
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.
Note!
Valid for ESM-11: Do not move the sensor after it has been
fastened in order to avoid damage to the sensor element.

Constant light:
The fl ow temperature is in the neutral zone
and the motor does not receive sig nals. The valve is not
activated.

Test of controller and sensors
Turn the function switch in position
. After about fi ve
sec. the lamp will fl ash and show the test result. The result
is shown every third sec.
No light:
The controller is defective or the fl ow
temperature sen sor is not mount ed.
Constant light with 1, 2 or 3 intervals:
The number of

Communication
The ECL Comfort controller can be connected to
external units via the ECL Comfort BUS.
Master / slave systems
If the controller is part of a larger system with several
controllers, you can connect the controllers with each other
and send information to them using the same outdoor sensor.
The controller which is physically connected with the out door
sensor is the master of the entire system and gets the address
15. The other controllers in the system can be addressed with
a slave number and receive information from the outdoor
sensor through the master.
If a slave has an address higher than 0, a reference
temperature demand can be sent to the master. The master
sends an outdoor temperature signal to the slaves. When a
slave has the address 0, only the outdoor temperature signal
is transferrred from the master to the slave.

Power back-up for your ECL Comfort controller
To ensure power back-up there is a battery placed above the
clock. Normally this battery is not in operation.
However Danfoss recommends to replace it every 2 years. Use
an Alcaline AAA 1.5 V type.
Remove the battery holder and replace the battery.
Remount the holder again.

Heating circuit
The circuit for heating the room/building.
Pt 1000 ohm sensor
All sensors used with the ECL Comfort controller is based on
the Pt 1000 ohm type. The resistance is 1000 ohms at 0 °C and
it changes with 3.9 ohms/degree C.
Reduced temperature
A period with decreased temperature.
Room sensor
A sensor placed in the room where the temperature is to be
controlled. The sensor is based on the Pt 1000 ohm type.
Room temperature
The temperature measured with the room sensor. The room
temperature can be controlled only when the sensor is
installed.
Weather compensation
A facility that enables the controller to take the outdoor
temperature into consideration for heat ing con trol.
This control is based on a user defi nable heat curve which
determines what the fl ow temperature should be when the
outdoor temperature varies.
Defi nitions
Actual flow temperature
The temperature that is measured in the fl ow at any
time.
Comfort period
A period of the day where comfort temperature is
selected.
Comfort temperature
The temperature maintained in the heating or hot water
circuits during comfort periods, which normally means
during daytime.
Function selector
A facility which makes it possible to override the mode of the
controller.
