Description and application The controller is designed for easy installation:
one cable, one connector.
The ECL Comfort 110 controller has a custom-
designed display with backlight. For a quick
overview, the display readouts are based on
graphic symbols as well as text.
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. Room panel or remote control (ECA 60
/ 61) can be connected.
The ECL Comfort 110 controller can be used as
master or slave in controller systems.
It is prepared for mounting on a DIN rail, a wall
or in a panel.
The ECL Comfort 110 is a universal 1-circuit
controller for use in district heating substations
and district heating systems as well as boiler-
based systems.
The product is an electronic controller for
• weathercompensatedowtemperature
control (heating)
• constanttemperaturecontrol(domestichot
water e.g.)
and prepared for new applications by means of
chip card and communication interface.

The ECA 110 is a supplement to the ECL Comfort 110 versions without a timer program, e.g., the code nos. 087B1261 and
087B1251 (see page 1). With the ECA 110 it will be possible to set personal schedules in terms of start and stop times of
the system and thereby optimize the energy supply.

Constant DHW temperature control with heat exchanger
Basic principles Constant DHW temperature control with heat
exchanger or storage tank
Typically,theowtemperatureisadjusted
accordingtothedesiredowtemperature.
• AdjustmentofDHWtemperature
IfthemeasuredDHWtemperatureislower
than the desired temperature, the motorized
control valve is opened gradually and vice
versa.
• Returntemperaturelimitation
The return temperature to the district heating
supply should not be too high. If so, the
desiredowtemperaturecanbeadjusted
(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
adjustmentprocedureasabove).
• Circulationpumpcontrol
The circulation pump is ON when the desired
DHWtemperatureishigherthanauser-
defined value (factory setting: 20 °C).

Key functions Flow temperature control
• Returntemperaturelimitation
The controller automatically changes the
desiredowtemperaturetoobtainan
acceptable return temperature when the
return temperature falls below or gets higher
than the set value. The return temperature

owlimitation.
Optimization
• Autotuning
A function for automatically setting the
proportional band (Xp) and integration time
constant (Tn).
Safety functions
• Frostprotection
The controller automatically switches
thecirculationpumpONwhentheow
temperature is lower than a user-defined
value (factory setting: 10 °C).
• Motorprotection
The controller prevents unstable temperature
control thus resulting in a longer life of the
actuator.
• Pumpexercise
Exercise of the pump to avoid blocking in
periods without heat demand.

Basic principles Control of district heating circuits with or
without heat exchanger and for boiler-based
heating circuits
Typically,theowtemperatureisadjusted
accordingtothedesiredowtemperature.
• Adjustmentofowtemperature
Thedesiredowtemperatureiscalculated
in the ECL Comfort controller, based on the
outdoor temperature. The lower the outdoor
temperature,thehigherthedesiredow
temperature.
The motorized control valve is opened
graduallywhentheowtemperatureislower
thanthedesiredowtemperatureandvice

• Returntemperaturelimitation
The return temperature to the district heating
supply should not be too high. If so, the
desiredowtemperaturecanbeadjusted
(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
adjustmentprocedureasabove).
• Roomtemperaturelimitation
If the measured room temperature does not
equal the desired room temperature, the
desiredowtemperaturecanbeadjusted.
• Circulationpumpcontrol
The circulation pump is ON when the desired
owtemperatureishigherthanauser-dened
value (factory setting: 20 °C ) or the outdoor
temperature is lower than a user-defined
value (factory setting: 2 °C).
