Save energy - save money - improve your comfort
temperature
The ECL Comfort controller series is designed by Danfoss for
temperature control of heating, hot-water, ventilation and
cooling systems.
The ECL Comfort controller ensures you of the following;
•
Room, hot-water, ventilation or cooling temperatures will
be adjusted to your personal settings.
•
Lower temperatures and lower energy consumption
reduce costs and ensure optimum use of energy resources.
Sketch your application
The ECL Comfort controller series is designed for a wide
range of heating, hot-water, and cooling systems with
di erent con gurations and capacities.
If your system di ers 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 nal
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 instruction. These settings could be related either to recent
updates or the use of optional modules (which are described in
the instructions in question).

Basic principles of the L32 application
Typical use:
Typically the ow temperature is always adjusted according to
comfort requirements. The colder it gets outdoor, the higher
the ow temperature of the oor circuit will be. When heating
is required, the heat generator (which typically is the boiler) is
activated.
When the outdoor temperature increases and heating operation
no longer is required, the controller can switch to cooling.
Chilled water is then circulated in the system to keep the room
temperature on the comfort level. When cooling is required,
the cooling generator (a water chiller) is activated. The ow
temperature is controlled with due consideration to the air
humidity. The controller avoids condensation on the oor.
Humidity and room temperature are measured by the remote
control ECA 63.
Program for the drying of oor pavement:
A special program for the drying of newly made concrete oor
pavement can be activated. For 3 days the oor temperature will
typically be held at 25
o
C and for the next 4 days typically at
50
o
C. In section 32 you can read more about activation, advice
and settings.

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 ow outlet.
Make sure that the surface of the pipe is clean 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 ow.
Room temperature sensor (ESM-10, ECA 60 / ECA 62
room panel or ECA 61 / ECA 63 remote control)
Place the room temperature 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.
Hot-water temperature sensor (ESMU or ESMB)
Place the hot water sensor according to the
manufacturer’s speci cation.
Boiler temperature sensor (ESMU, ESM-11 or ESMC)
Place the sensor according to the boiler manufacturer’s
speci cation.
Flow / air duct temperature sensor (ESM-11, ESMB,
ESMC or ESMU types)
Place the sensor close to the exchanger.
Surface temperature sensor (ESMB-12)
Place the sensor in the surface of the oor.
Valid for ESM-11: Do not move the sensor after it has been
fastened in order to avoid damage to the sensor element.

How to insert your ECL Card the rst 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 system type and
factory settings from the ECL Card. After copying, the display
will show the system type the controller is set to control. After
approx. 10 sec. the display will change to display line C.

Understanding the ECL Card
The ECL Card contains factory settings for a standard
system. If the actual system di ers 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 cannot be changed after approx.
25 min.
•
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!
When you store your personal settings on your ECL Card, your
factory settings will be overridden.

How to determine another heat curve, if necessary:

Pick the heat curve closest to the crossing point of these two
values.
The setting of the desired room temperature has an in uence
on the calculated ow temperature (heat curve), no matter if a
room temperature sensor is connected or not.
Floor heating systems
This controller is factory set for radiator systems, which typically
are high ow temperature systems.
To control oor heating systems, which typically are low ow
temperature systems, you need to change the heat curve
according to your type of system.
