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
• weathercompensatedowtemperature
control (heating)
• constanttemperaturecontrol(domestichot
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,theowtemperatureisadjusted
accordingtothedesiredow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.
• Returntemperaturelimitation
The return temperature to the district heating
supply should not be too high. If so, the
desiredow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user-
defined value (factory setting: 20 °C).

Key functions Flow temperature control
• Returntemperaturelimitation
The controller automatically changes the
desiredowtemperaturetoobtainan
acceptable return temperature when the
return temperature falls below or gets higher
than the set value. The return temperature
inuencecanbelimitedbythemin./max.

Optimization
• Autotuning
A function for automatically setting the
proportional band (Xp) and integration time
constant (Tn).
Safety functions
• Frostprotection
The controller automatically switches
thecirculationpumpONwhentheow
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
actuator.
• Pumpexercise
Exercise of the pump to avoid blocking in
periods without heat demand.
