Sketch your application
The ECL Comfort controller series is designed for a wide
range of heating, domestic hot-water (DHW) and cooling
systems with dierent congurations and capacities.
If your system diers 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 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 C17 is very exible. These are the basic principles:
Typically, the tank temperature (S6) is adjusted according to your
requirements. The charging temperature sensor (S2) is the most
important sensor. The desired charging temperature at S2 is set in
the ECL controller (line C, yellow side).
If the measured DHW temperature (S6) is lower than the desired
charging temperature minus the cut-in dierence, charging
starts. The charging pump, P2, is switched ON.
When the measured DHW temperature (S5) is higher than the
desired charging temperature minus the cut-out dierence,
charging stops.
The motorized control valve (M1) is opened gradually when the
charging temperature is lower than the desired charging
temperature and vice versa.
Typically, the return temperature (S4) to the district heating
supply should be as low as possible. If not so, the desired
charging temperature can be adjusted.
The S1 temperature can correct the proportional band (Xp).
Typically, the Xp must be increased at a rising S1 temperature.
The S3 temperature gives a feedback to the DHW charging
temperature (S2). If the S3 temperature is too low, the desired
temperature at S2 will be increased.

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 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 ow.
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 specication.
Boiler temperature sensor (ESMU, ESM-11 or ESMC)
Place the sensor according to the boiler manufacturer’s
specication.
Flow / air duct temperature sensor (ESM-11, ESMB-12,
ESMC or ESMU types)
Place the sensor so that it measures a representative
temperature.
Slab temperature sensor (ESMB-12)
Place the sensor in the slab.
Valid for ESM-11: Do not move the sensor after it has been
fastened in order to avoid damage to the sensor element.

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 ope ration
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
inuence from contact resistance, the use of ECA 9010 is
recommended.

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 application type
and factory settings from the ECL Card. After copying, the
display will show you the application type. 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 diers 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 calculate the running time of a motorized
control valve
The running time of the motorized control 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.

7 Neutral zone, Nz
Circuit Setting range Factory setting
I 0 ... 9 K 3 K
Set the neutral zone to a high value if you can
accept a high variation in ow temperature.
When the actual ow temperature is within the
neutral zone, the controller does not activate the
motorized valve.
The neutral zone is symmetrical around the desired ow
temperature value, i.e. half the value is above and half the value is
below this temperature.
Control parameters (lines 4 -7) are overruled if thermo actuator is
chosen (OFF).
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.
Temp.
Critica l time period
Time
This time period will be characteristic for the system, and you can
evaluate the set tings 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%.
Make sure there is a consumption when you set the parameters.

Air duct temperature
Temperature measured in the air duct where the temperature is
to be controlled.
Balance temperature
This setpoint is the basis for the ow / air duct temperature. The
balance temperature can be adjusted by the room temperature,
the compensation temperature and the return temperature.
The balance temperature is only active if a room temperature
sensor is connected.
Comfort operation
Normal temperature in the system controlled by the schedule.
During heating the ow temperature in the system is higher
to maintain the desired room temperature. During cooling the
ow temperature in the system is lower to maintain the desired
room temperature.
Comfort temperature
Temperature maintained in the circuits during comfort periods.
Normally during daytime.
Compensation temperature
A measured temperature inuencing the ow temperature
reference / balance temperature.
Controller mode indicator
Black arrow to the right of the symbols indicating the present
mode.
Desired room temperature
Temperature which is set as the desired room temperature.
The temperature can only be controlled by the ECL Comfort
controller if a room temperature sensor is installed.
If a sensor is not installed, the set desired room temperature
however still inuences the ow temperature.
In both cases the room temperature in each room is typically
controlled by radiator thermostats / valves.
Desired temperature
Temperature based on a setting or a controller calculation.
Dew point temperature
Temperature at which the humidity in the air condensates.
Factory settings
Settings stored on the ECL Card to simplify the set up of your
controller the rst time.
Flow temperature
Temperature measured in the ow at any time.
Flow temperature reference
Temperature calculated by the controller on basis of the
outdoor temperature and inuences from the room and / or
return temperatures. This temperature is used as a reference for
the control.
Heating circuit
The circuit for heating the room / building.
Heating curve
A curve showing the relationship between actual outdoor
temperature and required ow temperature.
DHW circuit
The circuit for heating the domestic hot water (DHW).
7b
Humidity, relative
This value (stated in %) refers to the indoor moisture content
compared to the max. moisture content. The relative humidity
is measured by the ECA 62 / 63 and is used for the calculation of
the dew point temperature.
Limitation temperature
Temperature that inuences the desired ow / balance
temperature.
Pt 1000 sensor
All sensors used with the ECL Comfort controller are based
on the Pt 1000 type. The resistance is 1000 ohm at 0 °C and it
changes with 3.9 ohm / degree.
Optimization
The controller optimizes the start time of the scheduled
temperature periods. Based on the outdoor temperature, the
controller automatically calculates when to start in order to
reach the comfort temperature at the set time. The lower the
outdoor temperature, the earlier the start time.
Return temperature
The temperature measured in the return inuences the desired
ow temperature.
Room temperature sensor
Temperature sensor placed in the room (reference room,
typically the living room) where the temperature is to be
controlled.
Room temperature
Temperature measured by the room temperature sensor, room
panel or remote control. The room temperature can only be
controlled directly if a sensor is installed. The room temperature
inuences the desired ow temperature.
Schedule
Schedule for periods with comfort and setback / saving
temperatures. The schedule can be made individually for each
week day and may consist of up to 3 comfort periods per day.
Setback / saving temperature
Temperature maintained in the heating / DHW circuit during
setback temperature periods.
State / mode indicators
White arrow to the left of the symbols (sun / moon). The white
arrow indicates the present state, comfort (sun) or setback /
saving (moon), when the controller is in scheduled operation
mode.
The black arrow symbol indicates the mode of the controller.
Time line / bar
Line with numbers representing the hours. Below the time
line, time bars represent scheduled periods with comfort
temperature. The bar is divided into half hour sections.
Weather compensation
Flow temperature control based on the outdoor temperature.
The control is related to a user-dened cooling curve.

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 ow temperature
is too low. Increase the desired room temperature (section

temperature (section 20).
The room temperature is too high during saving
periods?
Make sure that the max. ow temperature limitation is not

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 in general

Horizontally the ECL Card is divided into lines that
represent the dierent 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.
