ECL Comfort 110
230 V a.c. and 24 V a.c.
Description and application
ECL Comfort 110 The ECL Comfort 110 is a universal 1-circuit
controller for use in district heating substations
and district heating systems as well as boilerbased systems.
The product is an electronic controller for
• weather compensated flow temperature
control (heating)
• constant temperature control (for example
Domestic Hot Water, DHW)
• constant temperature control (DHW on
demand)
In heating applications the ECL Comfort 110 can
be integrated with the Danfoss Link™ solution
via the DLG interface for use in single-family
applications.
The controller is designed for easy installation:
one cable, one connector.
The ECL Comfort 110 controller has a customdesigned display with backlight. For a quick
overview, the display readouts are based on
graphic symbols as well as text in various
languages.
The controller has triac outputs for motorized
control valve and relay outputs for pump
control.
It is possible to connect up to 4 temperature
sensors (Pt 1000 types) and it has 1 input for
override.
The ECL Comfort 110 controller can be used as
master or slave in ECL 100, ECL 110, ECL 200,
ECL 300 and ECL 301 systems.
It is prepared for mounting on a DIN rail, a wall
or in a panel.
ECL Comfort 110 works with a limited range of
Danfoss actuators. See list.

Domestic hot water (DHW)
(Application 116)
Application 116, example 1
Constant DHW temperature control with heat e xchanger
Basic principles Constant DHW temperature control with heat
exchanger or storage tank
Application 116, example 2:
Typically, the flow temperature is adjusted
according to the desired flow temperature.
• Adjustment of DHW temperature
If the measured DHW temperature is lower
than the desired temperature, the motorized
control valve is opened gradually and vice
versa.
S2
• Return temperature limitation
The return temperature to the district
heating supply should not be too high. If so,
the desired flow temperature can be
adjusted (typically to a lower value) thus
resulting in a gradual closing of the
motorized control valve. In boiler-based
heating supply the return temperature
should not be too low (same adjustment
procedure as above).
• Circulation pump control
The circulation pump is ON when the desired
DHW temperature is higher than a userdefined value (factory setting: 20 °C).

Data sheet ECL Comfort 110
Basic principles Desired DHW temperature, for example 55 °C, is
controlled as long as a flow is detected by flow
switch FS.
The temperature at S2 corrects the set
Proportional band (Xp) in order to achieve stable
control at different supply temperatures.
Key functions Flow temperature control
• Return temperature limitation
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 value. The return temperature
influence factor is set in the ECL 110.
Optimization
• Auto tuning
A function for automatically setting the
proportional band (Xp) and integration time
const ant ( Tn).
Heating
(Application 130)
When no DHW flow is detected, the ECL 110 can
maintain a minimum supply temperature at S2.
DHW circulation temperature, for example 55 °C,
can be maintained.
Safety functions
• Frost protection
The controller automatically switches the
circulation pump ON when the flow
temperature is lower than a user-defined
value (factory setting: 10 °C).
• Motor protection
The controller prevents unstable
temperature control thus resulting in a
longer life of the motorized control valve and
actuator.
• Pump exercise
Exercise of the pump to avoid blocking in
periods without heat demand.

Data sheet ECL Comfort 110
Basic principles Control of district heating circuits with or without
heat exchanger and for boiler-based heating
circuits
Application with
Danfoss Link™
Typically, the flow temperature is adjusted
according to the desired room temperature.
The desired room temperature (Comfort and
Setback) can be determined by the week
schedule.
• Adjustment of flow temperature
The desired flow temperature is calculated in
the ECL Comfort controller, based on the
outdoor temperature. The lower the outdoor
temperature, the higher the desired flow
temperature.
The heat curve (relationship between outdoor
temperature and desired flow temperature) is
set by means of a slope value. Max. / min.
limitation of the desired flow temperature can
be set.
The motorized control valve is opened gradually
when the flow temperature is lower than the
desired flow temperature and vice versa.
• Return temperature limitation
The return temperature to the district heating
supply should not be too high. If so, the desired
flow temperature can be adjusted (typically to
a lower value) thus resulting in a gradual closing
of the motorized control valve. In boiler-based
heating supply the return temperature should
not be too low (same adjustment procedure as
above).
• Room temperature limitation
If the measured room temperature does not
equal the desired room temperature, the
desired flow temperature can be adjusted.
• Circulation pump control
The circulation pump is ON when the desired
flow temperature is higher than a user-defined
value (factory setting: 20 °C ) or the outdoor
temperature is lower than a user-defined value
(factory setting: 2 °C).
• The heating cut-out function can switch OFF
the heating and stop the circulation pump at
high outdoor temperatures.
