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).
