ECL Comfort 210 / 310, application A214 / A314
2.0 Installation
2.1 Before you start
Typical A214.1 application:
S1
Da nfos s
87H2113.10
The Application Key A214 contains several applications, mainly
related to ventilation systems with heating or cooling or a
combination of these. The applications in the A214 key offer a wide
range of possibilities (see the examples).
ECL 210 / (310)
R4 (R6)
The application A214.1 is very flexible. These are the basic
principles:
M2
Cooling with room temperature control:
S5
Typically, the duct temperature is adjusted according to your
requirements. The duct temperature sensor S3 is the most
important sensor. The desired temperature at S3 is set in the ECL
Comfort controller as the 'Desired balance temperature'.
X3
P2
F1
S3
S4
The motorized control valve M2 (controlling the cooling transfer) is
opened gradually when the duct temperature is higher than the
desired duct temperature and vice versa.
Room temperature:
If the measured room temperature (S4 or ECA 30) does not equal
the desired room temperature, the desired temperature at S3 can
be adjusted.
By means of a week schedule (up to 3 ‘Comfort’ periods / day), the
cooling circuit can be in ‘Comfort’ or ‘Saving’ mode (two different
temperature values for desired room temperature).
The desired room temperature determines a correction of the
desired temperature at S3.
If the room temperature is not measured, the desired room
temperature equals (will be) the desired temperature at S3. In this
case, the setting of the 'Balance temperature' is not considered (or:
has no influence).
The shown diagram is a fundamental and simplified example and does
not contain all components that are necessary in a system.
All named components are connected to the ECL Comfort controller.

If the measured return temperature (S5) does not equal the
limitation value (typically, the return temperature becomes lower
than the limitation value), the desired temperature at S3 can be
adjusted (typically to a higher value). This results in a gradual
closing of the motorized control valve.
(R6)
Relay output, alarm, ECL Comfort 310
The fan (F1) is ON / OFF controlled according to the schedule and
cooling demand. The damper (P2) is ON / OFF controlled according
to schedule. The circulation pump (X3) is ON / OFF controlled
according to cooling demand.
A simple frost protection (via S5) can be established. Furthermore,
it is expected that the cooling exchanger (fan coil) circuit contains
brine.

The cooling section can be passive (re-circulation) or active.
Room temperature:
If the measured room temperature (S4) does not equal the desired
room temperature, the desired temperature at S3 can be adjusted.
A too low room temperature will activate the heating circuit (M1),
whereas a too high room temperature will activate the cooling
circuit (M2).
By means of a week schedule (up to 3 ‘Comfort’ periods / day), the
heating circuit can be in ‘Comfort’ or ‘Saving’ mode (two different
temperature values for desired duct temperature).
The desired duct temperature determines a correction of the
desired temperature at S3 in heating mode. In cooling mode the
cooling is OFF during 'Saving'.
The fan (F1) is ON / OFF controlled according to the schedule and
heating / cooling demand. The damper (P2) is ON / OFF controlled
according to schedule. The circulation pump (X3) is ON / OFF
controlled according to heating demand.
For a description of alarms, compensation temperature, return
temperature limitation (S5) and frost protection (S6 and S7), please

A214 and A314 in general:
Compensation temperature (optional):
If the measured compensation temperature (S1 or S2) is higher or
lower than the limitation value, the desired temperature at S3 can
be adjusted. The compensation temperature can be measured
by the outdoor temperature sensor or for example an additional
room temperature sensor.
Override possibilities:
Unused input can, by means of an override switch, be used to
override the schedule to a fixed 'Comfort' or 'Saving' mode.
Alarm functions:
The alarm (relay 4 in ECL 210, relay 6 in ECL 310) is activated:
1. If an unaccepted deviation between the desired and actual S3
temperature occurs.
2. If a frost thermostat (S7) is activated.
3. If a frost temperature is detected at S5 or S6.
4. If the fire alarm (S8) is activated.
5. If a temperature sensor or its connection disconnects / short
circuits.
A214.2, A214.3, A214.4, A214.5, A314.1, A314.2 and A314.3:
Return temperature (optional):
If the measured return temperature (S5) does not equal the
limitation value (typically, the return temperature becomes higher
than the limitation value), the desired temperature at S3 can be
adjusted (typically to a lower value). This results in a gradual closing
of the motorized control valve.
Frost protection (optional):
Temperature sensor S6 and / or frost thermostat S7 can protect
the heat exchanger against frost.
Furthermore, if the S5 temperature becomes too low, it also can
enable the frost protection.
An activated frost protection will start the alarm, stop the fan F1,
close the damper P2 and fully open the motorized control valve M1.
Fire alarm (optional):
An activated fire alarm input will start the alarm, stop the fan F1,
close the damper P2 and close the motorized control valves.
The controller is pre-programmed with factory settings that are shown
in the relevant chapters of this guide.

2.2 Identifying the system type
Sketch your application
The ECL Comfort controller series is designed for a wide range
of heating, domestic hot-water (DHW) and cooling systems with
different configurations and capacities. If your system differs
from the diagrams shown here, you may want to make a sketch
of the system about to be installed. This makes it easier to use
the Installation Guide, which will guide you step-by-step from
installation to final adjustments before the end-user takes over.
The ECL Comfort controller is a universal controller that can be
used for various systems. Based on the shown standard systems,
it is possible to configure additional systems. In this chapter you
find the most frequently used systems. If your system is not quite
as shown below, find the diagram which has the best resemblance
with your system and make your own combinations.
The circulation pump(s) in heating circuit(s) can be placed in the flow
as well as the return. Place the pump according to the manufacturer’s
specification.

2.3 Mounting
2.3.1 Mounting the ECL Comfort controller
For easy access, you should mount the ECL Comfort controller near
the system. Select one of the following methods using the same
base part (code no. 087H3220 (ECL Comfort 210) or 087H3230 (ECL
Comfort 310):
•
Mounting on a wall
•
Mounting on a DIN rail (35 mm)
The ECL Comfort 210 can be mounted in the ECL Comfort 210 /
310 base part.
The ECL Comfort 310 can only be mounted in the ECL Comfort
310 base part.
Screws, PG cable glands and rawlplugs are not supplied.
Locking the ECL Comfort controller
In order to fasten the ECL Comfort controller to its base part, secure
the controller with the locking pin.
To prevent injuries to persons or the controller, the controller has to
be securely locked into the base. For this purpose, press the locking
pin into the base until a click is heard and the controller no longer
can be removed from the base.
If the controller is not securely locked into the base part, there is a risk
that the controller during operation can unlock from the base and the
base with terminals (and also the 230 V a.c. connections) are exposed.
To prevent injuries to persons, always make sure that the controller
is securely locked into its base. If this is not the case, the controller
should not be operated!
The easy way to lock the controller to its base or unlock it is to use a
screw driver as lever.

2.4 Placing the temperature sensors
2.4.1 Placing the temperature sensors
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 210 and 310 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 temperature sensor should always be placed so that it
measures a representative return temperature.
Room temperature sensor (ESM-10, ECA 30 / 31 Remote Control
Unit)
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.
Boiler temperature sensor (ESMU, ESM-11 or ESMC)
Place the sensor according to the boiler manufacturer’s
specification.
Air duct temperature sensor (ESMB-12 or ESMU types)
Place the sensor so that it measures a representative temperature.
ESM-11: Do not move the sensor after it has been fastened in order to
avoid damage to the sensor element.
DHW temperature sensor (ESMU or ESMB-12)
Place the DHW temperature sensor according to the manufacturer’s
specification.
Slab temperature sensor (ESMB-12)
Place the sensor in a protection tube in the slab.

2.6.2 ECL Application Key, copying data
General principles
When the controller is connected and operating, you can check
and adjust all or some of the basic settings. The new settings can
be stored on the Key.
Factory settings can always be restored.
How to update the ECL Application Key after settings have
been changed?
All new settings can be stored on the ECL Application Key.
How to store factory setting in the controller from the
Application Key?
Please read the paragraph concerning Application Key, Situation
1: The controller is new from the factory, the ECL Application Key
is not inserted.
Make a note of new settings in the 'Settings overview' table.
How to store personal settings from the controller to the Key?
Please read the paragraph concerning Application Key, Situation 3:
A copy of the controllers settings is needed for configuring another
controller
Do not remove the ECL Application Key while copying. The data on
the ECL Application Key can be damaged!
As a main rule, the ECL Application Key should always remain in
the controller. If the Key is removed, it is not possible to change
settings.
Danfoss District Energy
It is possible to copy settings from one ECL Comfort controller to
another controller provided that the two controllers are from the same
series (210 or 310).

3.4 Monitoring temperatures and system components
This section describes the function in general for the ECL Comfort
210 / 310 series. The shown displays are typical and not application
related. They might differ from the displays in your application.
Heating circuit
The overview display in the heating circuit ensures a quick
overview of the actual and (desired) temperatures as well as the
actual state of the system components.
Display example:
49 °C
(31)
24 °C
(50)
Flow temperature
Desired flow temperature
Return temperature
Return temperature limitation
Input overview
Another option to get a quick overview of measured temperatures
is the 'Input overview' which is visible in the common controller
settings (how to enter the common controller settings, see
‘Introduction to common controller settings’.)
As this overview (see display example) only states the measured
actual temperatures, it is read-only.

3.5 Influence overview
This section describes the function in general for the ECL Comfort
210 / 310 series. The shown displays are typical and not application
related. They might differ from the displays in your application.
The menu gives an overview of the influences on the desired
flow temperature. It differs from application to application which
parameters are listed. It can be helpful in a service situation to
explain unexpected conditions or temperatures among others.
If the desired flow temperature is influenced (corrected) by one or
more parameters, it is indicated by a small line with arrow-down,
arrow-up or double-arrow:
Arrow-down:
The parameter in question reduces the desired flow temperature.
Arrow-up:
The parameter in question increases the desired flow temperature.
Double-arrow:
The parameter in question creates an override (e.g. Holiday).
Straight line:
No active influence.
In the example, the arrow in the symbol points downwards for
'Room lim.'. This means that the actual room temperature is
higher than the desired room temperature which again results in a
decrease of the desired flow temperature.

5.2 Room limit
This section is only relevant if the A214 application works with
room temperature signal (a room temperature sensor or a Remote
Control Unit) is used. The applications are: A214.1, A214.3, A214.5,
A314.2 and A314.3.
Influence
‘Infl. - min.’ (min. limitation)
Desired room temperature
Actual room temperature
The controller adjusts the desired flow / duct temperature to
compensate for the difference between the desired and the actual
room temperature.
‘Infl. - max.’ (max. limitation)
If the room temperature is higher than the desired value, the
desired flow temperature can be reduced.
The ‘Infl. - max.’ and 'Infl. - min.' determine how much the room
temperature should influence the desired flow / duct temperature.
The 'Infl. -max.' (Influence, max. room temp.) determines how
much the desired flow temperature should be reduced.
Use this influence type to avoid a too high room temperature.
If the room temperature is lower than the desired value, the desired
flow temperature can be increased.
The 'Infl. -min.' (Influence, min. room temperature) determines
how much the desired flow temperature should be increased.
If the ‘Infl.’ factor is too high and / or the ‘Adapt. time’ too low, there is
a risk of unstable control.
Example 1:
The actual room temperature is 2 degrees too high.
The ‘Infl. - max.’ is set to -4.0.
The ‘Infl. - min.’ is set to 3.0.
Result:
The desired flow / duct temperature is decreased by 2 x -4.0 = 8.0
degrees.
Use this influence to avoid a too low room temperature. The
controller will allow for free heat gains, i.e. solar radiation etc.
A typical setting will be -4.0 for 'Infl. -max.' and 4.0 for 'Infl. -min.'
Example 2:
The actual room temperature is 3 degrees too low.
The ‘Infl. - max.’ is set to -4.0.
The ‘Infl. - min.’ is set to 3.0.
Result:
The desired flow / duct temperature is increased by 3 x 3.0 = 9.0
degrees.

5.4 Return limit
This section describes the function in general for the ECL Comfort
210 / 310 series. The shown displays are typical and not application
related. They might differ from the displays in your application.
The return temperature limitation is based on a constant
temperature value.
Influence
‘Infl. - min.’ > 0
The controller automatically changes the desired flow temperature
to obtain an acceptable return temperature when the return
temperature falls below or gets higher than the set limit.
‘Limit’
‘Infl. - max.’ > 0
Return temperature
This limitation is based on a PI regulation where P ('Infl.' factor)
responds quickly to deviations and I ('Adapt. time') responds
slower and over time removes the small offsets between the
desired and actual values. This is done by changing the desired
flow temperature.
‘Infl. - max.’ < 0
‘Infl. - min.’ < 0
If the ‘Infl.’ factor is too high and / or the ‘Adapt. time’ too low, there is
a risk of unstable control.

Combination of two compensation temperature limit points:
Compensation 1 and 2 can be combined to give a compensation at
2 different compensation temperatures. This can for instance be
used to avoid a too big difference between the indoor and outdoor
temperatures.
Regarding compensation temperatures, example 1 shows that
below Comp. 1 and above Comp. 2, the desired flow temperature
will be increased, but with different values.
Example 1:
Example 1:
Comp. 1 value is set to 21 °C and Comp. 2 value is set to 25 °C.

'Infl. min.' for Comp. 1 is set to 2.5 and 'Infl. max.' for Comp. 1 is
set to 0.0.

'Infl. min.' for Comp. 2 is set to 0.0 and 'Infl. max.' for Comp. 2 is
set to 1.5.
The desired flow temperature is kept on a constant level as long
as the compensation temperature is between 21 and 25 °C, but
the desired flow temperature will rise if the the compensation
temperature gets above 25 °C or below 21 °C.

of a stop watch.
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.)

If you want to tune the PI regulation precisely, you can use the following method:
•
Set the ‘Tn’ (integration time constant) to its max. value (999 sec.).
•
Decrease the value for the ‘Xp’ (proportional band) until the system starts hunting (i.e. gets unstable) with a constant amplitude (it
might be necessary to force the system by setting an extreme low value).
•
Find the critical time period on the temperature recorder or use a stop watch.

Time
This critical time period will be characteristic for the system, and you can evaluate the settings from this critical period.
‘Tn’ = 0.85 x critical time period
‘Xp’ = 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.

Wind influence on fan speed
A wind speed sensor can be connected to the ECL controller in
order to control the fan speed. Typically, the more windy, the
higher the fan speed.
The signal from the wind speed sensor is a 0-10 volt signal which
is applied directly to input S10. The voltage rises at higher wind
speed.
The measured voltage on input S10 must be converted to a wind
speed value by the controller.
The following procedure sets up the scaling.

Typical alarms, type 1:
•
Actual S3 temperature differs from the desired S3 temperature.
•
Activation of a frost thermostat (S7).
•
Detection of frost temperature at S5 or S6.
•

the ECL 485 communication bus (cable type: 2 x twisted pair), the
master controller will broadcast the following signals to the slave
controllers:
•
Outdoor temperature (measured by S1)
•
Time and date
•
DHW heating activity
Furthermore, the master controller can receive information about
the desired flow temperature (demand) from slave controllers.

7.2 Frequently asked questions
The definitions apply to the Comfort 210 as well as ECL Comfort
310 series. Consequently, you might come across expressions
that are not mentioned in your guide.
The time shown in the display is one hour off?
See ‘Time and Date’.
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 72 hours.
Go to the 'Common controller settings' and 'Time & Date' to set
the correct time.
The ECL Application Key is lost?
Switch the power off and on again to see the system type and the
software generation of the controller or go to 'Common controller
settings' >'Key functions' > 'Application'. The system type (e.g.
TYPE A266.1) and the system diagram is displayed.
Order a replacement from your Danfoss representative (e.g. ECL
Application Key A266).
Insert the new ECL Application Key and copy your personal
settings from the controller to the new ECL Application Key, if
required.
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 (display with desired
room temperature). If this does not help, adjust the ‘Heat curve’
(‘Flow temp.’).
The room temperature is too high during saving periods?
Make sure that the min. flow temperature limitation ('Temp. min.')
is not too high.
The temperature is unstable?
Check that the flow temperature sensor is correctly connected
and in the right place. Adjust the control parameters ('Control
par.').
If the controller has a room temperature signal, see 'Room limit'.
The controller does not operate and the control valve is
closed?
Check that the flow temperature sensor is measuring the correct
value, see 'Daily use' or 'Input overview'.
Check the influence from other measured temperatures.
How to make an extra comfort period in the schedule?
You can set an additional comfort period by adding new ‘Start’
and ‘Stop’ times in ‘Schedule’.
How to remove a comfort period in the schedule?
You can remove a comfort period by setting start and stop times
to the same value.
How to restore your personal settings?
Please read the chapter concerning ‘Inserting the ECL Application
Key’.
How to restore the factory settings?
Please read the chapter concerning ‘Inserting the ECL Application
Key’.
Why can’t the settings be changed?
The ECL Application Key has been removed.

How to react on alarms?
An alarm indicates that the system is not operating satisfactorily.
Please contact your installer.
What does P and PI control mean?
P control: Proportional control.
By using a P control, the controller will change the flow
temperature proportional to the difference between a desired
and an actual temperature, e.g. a room temperature.
A P control will always have an offset which not will disappear
over time.
PI control: Proportional and Integrating control.
A PI control does the same as a P control, but the offset will
disappear over time.
A long ‘Tn’ will give a slow but stable control, and a short ‘Tn’ will
result in a fast control but with a higher risk of unstability.

7.3 Definitions
The definitions apply to the Comfort 210 as well as ECL Comfort
310 series. Consequently, you might come across expressions
that are not mentioned in your guide.
Air duct temperature
Temperature measured in the air duct where the temperature
is to be controlled.
Alarm function
Based on the alarm settings, the controller can activate an output.
Anti-bacteria function
For a defined period, the DHW temperature is increased in order
to neutralize dangerous bacteria, e.g. Legionella.
Balance temperature
This setpoint is the basis for the flow / 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 flow temperature in the system is higher to
maintain the desired room temperature. During cooling the flow
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 influencing the flow temperature
reference / balance temperature.
Desired flow temperature
Temperature calculated by the controller on basis of the outdoor
temperature and influences from the room and / or return
temperatures. This temperature is used as a reference for the
control.
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 influences the flow 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.
DHW circuit
The circuit for heating the domestic hot water (DHW).
Factory settings
Settings stored on the ECL Application Key to simplify the set up
of your controller the first time.
Flow temperature
Temperature measured in the flow at any time.

temperature.
Log function
The temperature history is displayed.
Master / slave
Two or more controllers are interconnected on the same bus,
the master sends out e.g. time, date and outdoor temperature.
The slave receives data from master and sends e.g. desired flow
temperature value.
Pt 1000 sensor
All sensors used with the ECL Comfort controller are based on the
Pt 1000 type (IEC 751B). 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.
Outdoor temperature trend
The arrow indicates the tendency, i.e. whether the temperature
rises or falls.
Refill water function
If the measured pressure in the heating system is too low (e.g.
due to a leakage), water can be supplemented.
Return temperature
The temperature measured in the return influences the desired
flow 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 or
the Remote Control Unit. The room temperature can only be
controlled directly if a sensor is installed. The room temperature
influences the desired flow temperature.
