Before you start
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 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 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.
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.
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 the optional module in
question.
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).
Both sides of the ECL Card are divided into lines
representing the different options of control and
programming.

14
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.
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 flow outlet.
Make sure that the surface of the pipe is clean where the
sensor is mounted.
Note!
Valid for ESM-11: 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.

The influence at min. limitation (left corner of the display) is
set to 20.
Heat curve H is 1.8.
Result:
The flow temperature reference is changed by
2 x 20 x 0.1 x H = 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

Heat curve H is 1.8.
Result:
The flow temperature reference is changed by
2 x (-35) x 0.1 x H = -12.6 degrees.
Basic set-up
This section is only relevant if you have installed a room
sensor or ECA 60 / 61. 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.
Select the max. influence.

Basic set-up
If you want to tune the PI-regulation precisely, you can
use the following method:
• Set the integration time (line 5) to its max. value (999 sec.).
• Decrease the value for the proportional band (Line 4) until
the system starts hunting with a constant amplitude (it might
be necessary to force the system by setting an extreme
value).
• Find the critical time period on the temperature recording or
use a stop watch.
This time period will be characteristic for the system, and you
can evaluate the settings from this critical period.
Integration time = 0.85 x critical time period
Proportional band = 2.2 x proportional band value
in the critical time period.
If the regulation seems to be too slow, you can decrease the
proportional band value by 10%.
Note! Make sure there is a consumption when you set the
parameters.

Critical time period
How to calculate the running time of the motorized valve
The running time of the motorized valve is calculated using the
following methods:
Seated valves
Running time = Valve stroke (mm) x actuator speed (sec./mm)
Example: 5.0 mm x 15 sec./mm = 75 sec.
Rotating valves
Running time = Turning degrees x actuator speed (sec./degr.)
Example: 90 degrees x 2 = 180 sec.

A higher value will result in a stable, but slow
regulation of the flow temperature.
Go to line 7.
Set the neutral zone to a high value if you can
accept a large variation in flow temperature.
When the actual flow temperature lies within the
neutral zone, the controller does not activate the
motorized valve.
Note! The neutral zone is symmetrical around
the flow reference value.
Go to line 6.
Set the running time of the motorized valve
according to the example on opposite page. This
is the time it takes the valve to move from closed
to fully open position.
Go to line 5.
Set a high integration time constant to obtain a
slow but stable reaction to deviations.
A low integration time constant will make the

The setting of the reduced temperature
depends on the outdoor temperature, when the
outdoor temperature is higher than the set limit.
The lower the outdoor temperature, the less the
temperature reduction. When the outdoor tem-
perature is below the set limit, there is no tem-
perature reduction.
OFF: The reduced temperature setting will be
constant at all outdoor temperatures.

Set the influence of the min. return temperature
limitation.
If the displayed value does not equal 0, the
function prevents the return temperature from
getting below the setting in line 30.
Influence higher than 0:
The reference for the
flow temperature is increased, when the return
temperature gets below the setting in line 30.
Influence lower than 0:
The reference for the flow
temperature is decreased, when the return
temperature gets below the setting in line 30.
Adjust the adaptive function of the return
limiter. The setting will eliminate the difference
between the accepted and actual return
temperature by integrating the difference and
adjusting the reference for the flow temperature.
OFF: The flow temperature reference will not
be adjusted any further.
1: The flow temperature reference will be
adjusted quickly.
50: The flow temperature reference will be
adjusted slowly.
Service parameters 36-37
When the limit of the return temperature is exceeded, the
controller automatically changes the flow temperature
reference to obtain a set reference of the required return
temperature. The factors for the definite function of the
return limiter are set in lines 35 and 36.
Extended service
Set the acceptable return temperature limit.
Set the influence of the max. return temperature
limitation.
If the displayed value does not equal 0, the
function prevents the return temperature from
getting above the setting in line 30.
Influence higher than 0:
The reference value for
the flow temperature is increased when the
return temperature gets above the setting in line
30.
Influence lower than 0:
The reference value for
