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.

ECA 110* Timer program for ECL Comfort 110 (chip card) 087B1248

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

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.
