Data sheet
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.
• 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.

Boiler-based heating circuit
VD.KT.C11.02
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.
