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.
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 instruc tion. 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
This guide is divided into two parts:
• User’s Guide: Yellow sections 1-7
• Installer's Guide: Grey sections 10 and onwards
The application C25 is very flexible. These are the basic
principles:
Heating:
Typically, the flow temperature is always adjusted according to
your requirements.
The flow temperature sensor (S5) is the most important sensor.
The desired flow temperature at S5 is calculated in the ECL
controller based on the outdoor temperature (S1). The lower the
outdoor temperature, the higher the desired flow temperature.
The boiler is switched ON when the flow temperature is lower
than the desired flow temperature and vice versa. A switching
difference determines the ac tion.
The return temperature (S4) to the boiler should not be too low.
If so, the desired flow temperature can be adjusted, typically to a
higher value.
If the measured room temperature does not equal the desired
room temperature, the desired flow temperature can be adjusted.
DHW:
If the measured DHW temperature is lower than the desired DHW
temperature, the desired flow temperature at S5 is increased in
order to heat the DHW. DHW heating has priority, i.e. pump P2 is
ON and pump P1 is OFF (or changeover valve is activated and P1
is still ON).

Installation
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 (ESMT)
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 and even
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 temperature sensor (ESM-10, ECA 60 / 62 room
panel or ECA 61 / 63 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.
DHW temperature sensor (ESMU or ESMB-12)
Place the DHW temperature sensor according to the
manufacturer’s specification.
Boiler temperature sensor (ESMU, ESM-11 or ESMC)
Place the sensor according to the boiler manufacturer’s
specification.
Flow / air duct temperature sensor (ESM-11, ESMB-12,
ESMC or ESMU types)
Place the sensor so that it measures a representative
temperature.
Surface temperature sensor (ESMB-12)
Place the sensor in the surface of the floor.
Valid for ESM-11: Do not move the sensor after it has been
fastened in order to avoid damage to the sensor element.

Connecting the room panel / remote control
The ECA 60 / 61 / 62 / 63 is activated by the setting in line 10
(section 32).
The ECA 60 / 61 / 62 / 63 is powered by the system device bus
which means that the bus must be active. The bus is activated by
setting the controller address to 15 (section 32, line 199).
Override
For an active override, you have to choose the mode
“scheduled operation”! Input S1 ... S6 (ECL Card C14 only uses
S5) can be used for override purposes (section 32, line 141).
Connection example without ECA 9010
If the override switch has goldplated contacts, you can
choose one of the following solutions or a combination of
both:
(C14 = 21 only) (C14 = 21 only)
Closed switch: Closed switch:
Comfort temperature Setback temperature
Open switch: Open switch:
Scheduled op eration Scheduled operation
Connection example with ECA 9010
The ECA 9010 module is powered by the system device bus,
which means that the bus must be active. The bus is activated
by setting the controller address to 15 (line 199). To avoid
influence from contact resistance, the use of ECA 9010 is
recommended.

Installation
Understanding the ECL Card
The ECL Card contains factory settings for a standard
system. If the actual 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 schedules, 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 setting.
If the card is removed or left in the controller with the grey
side facing you, please note that:
• After approx. 25 min.:
- The controller cannot be operated.
- The controller reverts to display C (section 1).
• The ECL Card must not be exposed to direct heat or
sunshine.
If several controllers are installed in the system you can
write a title on the ECL Card with a permanent ink pen.
Do not remove the ECL Card while copying. The data on the
ECL Card can be damaged!
When you store your personal settings on your ECL Card, the
factory settings will be overridden.

How to determine another heat curve, if necessary:
Choose the calculated flow temperature for your system and
the determined min. outdoor temperature for your area.
Pick the heat curve closest to the crossing point of these two
values.
The setting of the desired room temperature has an influence
on the calculated flow temperature (heat curve), no matter if
a room temperature sensor is connected or not.
Floor heating systems
This controller is factor y set for radiator systems, which typically
are high flow temperature systems.
To control floor heating systems, which typically are low flow
temperature systems, you need to change the heat curve
according to your type of system.
Slope
Circuit Setting range Typical setting
I / (II) 0.2 ... 3.4 1.0 / (1.0)
Whether it is reasonable to change the slope or parallel

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.
Influe nce

limita tion
The max. influence determines how much the room
temperature should influence the desired flow temperature.
Example
The actual room temperature is 2 degrees too high.
The influence at max. limitation (right corner of the display) is
set to -40.
The influence at min. limitation (left corner of the display) is set
to 0.
Heat curve H is 1.8.
Result:
The desired flow temperature is changed by
2 x -40 x 1.8 x 0.1 = -14.4 degrees.

23b
B: Reference room temperature 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 the min. influence and a negative
value for the max. influence.
The room sensor in the reference room registers the
difference between the desired and the actual room
temperature. The desired flow temperature will be corrected
to eliminate this difference.
Example 1
The actual room temperature is 2 degrees too low.
The influence at max. limitation (right corner of the display) is
set to -35.
The influence at min. limitation (left corner of the display) is set
to 20.
Heat curve H is 1.8.
Result:
The desired flow temperature is changed by
2 x 20 x 1.8 x 0.1 = 7.2 degrees.
Example 2
The actual room temperature is 2 degrees too high.
The influence at max. limitation (right corner of the display) is
set to -35.
The influence at min. limitation (left corner of the display) is set
to 20.
Heat curve H is 1.8.
Result:
The desired flow temperature is changed by
2 x (-35) x 1.8 x 0.1 = -12.6 degrees.

The time shown in the display is one hour off?
See the summer time changeover in line 198, section 32.
The time shown in the display is not correct?
The internal clock may have been reset, if there has been a
power break for more than 12 hours.
Set time and date.
See section 17.
The ECL Card is lost?
Switch the power off and on again to see the
system type and the software generation of the controller.
Order a replacement from your Danfoss representative.
Insert the new ECL Card with the yellow side facing you and
make sure that you copy your personal settings from the
controller to the ECL Card.
See section 34.
The room temperature is too low?
Make sure that the radiator thermostat does not limit the
room temperature.
If you still cannot obtain the desired room temperature by
adjusting the radiator thermostats, the flow temperature
is too low. Increase the desired room temperature (section
3). If this does not help, adjust the heat curve / balance
temperature (section 20).
The room temperature is too high during setback
periods?
Make sure that the min. flow temperature limitation is not too
high. See section 22.
The temperature is unstable?
Check that the flow temperature sensor is correctly
connected and in the right place. Adjust the control
parameters (section 26).
If the controller has a room temperature signal, see section
23.
The controller does not operate and the control
valve is closed?
Check that the flow temperature sensor is measuring the
correct value, see section 1.
Check the influence from other measured temperatures.

Save energy - save money - improve
your comfort temperature
The ECL Comfort controller is designed by Danfoss for
the automatic temperature control of heating, hot-water,
ventilation and cooling systems.
Some of the advantages of the ECL Comfort controller system
are:
• Secure control and the optimum use of energy resources.
• Control of system temperatures according to seasonal
changes and variations in outdoor temperatures.
• Setback temperature periods and low energy consumption
while you are out or asleep save heating costs.
Operating the ECL Comfort controller
When operating the controller it is advisable to keep the lid
open in order to view the entire display.
During operation the ECL Card must be inserted with the
yellow side facing you.
The ECL Card, which is equipped with a memory chip, is
simple and easy to understand.
The ECL Card is divided vertically into two columns each
representing a circuit.
Horizontally the ECL Card is divided into lines that
represent the different control and programming options
for the two circuits. Each line is shown in the display of the
controller, which gives you an instant overview of the
operation, settings etc.
