Functions General functions:

• The ECL Comfort 210 has all the required

functions of a modern electronic temperature

controller for heating and DHW applications.

• The controller can be used as master or slave in

systems with master / slave ECL Comfort 210 /

310 controllers.

• The ECL Application Key contains the application

software for exible conguration. Furthermore,

an update of the controller software is done

automatically, if required.

• The ECL Comfort 210 contains, besides the

standard functions, log and alarm functions.

• The built-in Real Time Clock gives automatic

summer / winter time changeover, week and

holiday schedule.

• Motor protection, which ensures stable control

and a long life of the motorized control valve, is

available for most of the applications. In periods

without heat demand, the motorized control

valve is exercised to avoid blocking.

• Scheduled control (Comfort and Saving mode)

is based on a week program. A holiday program

gives the possibility to select days with comfort

or saving mode.

• The ECL Comfort 210 can receive pulses from a

heat or ow meter to limit the power or the ow.

• In many applications analog input (0 – 10 V) is

congured for pressure measuring among

others. The scaling is set in the controller.

• Some applications are congured to handle

digital input. This function can be used to have

an external switch to run comfort or saving mode

or react on a ow switch signal.

• The control parameters, proportional band (Xp),

integration time (Tn), running time of the

motorized control valve and neutral zone (Nz)

can be set individually for each output (3-point

control).

Heating functions:

• The heat curve (relationship between outdoor

temperature and desired ow temperature) is

set by means of 6 coordinate points or a slope

value. Max. / min. limitation of the desired ow

temperature can be set.

• The return temperature limitation can work in

relation to the outdoor temperature or be a xed

value.

• The heating cut-out function can switch OFF the

heating and stop the circulation pump at high

outdoor temperatures.

• Based on the room temperature the ECL Comfort

210 can correct the desired ow temperature in

order to increase the comfort level.

• The optimizer function ensures heating in the

desired periods (the lower outdoor temperature,

the earlier cut-in of the heating).

• The ramping function makes a smooth cut-in of

the heating valuable (district heating

installations).

• The boost function makes a powerful cut-in of

the heating (boiler based installations).

• The circulation pump is controlled in relation to

heat demand and frost protection. In periods

without heat demand, the circulation pump is

exercised to avoid blocking.

• The saving function gives two possibilities:

· reduced ow temperature with xed

reduction or reduction in relation to outdoor

temperature (the lower the outdoor

temperature, the less the reduction),

· heating o, still with active frost protection

DHW functions:

• The Auto Tuning function with automatic setting

of control parameters for constant DHW

temperature is integrated in the application A217

and A266. However, Auto Tuning is only

applicable with valves that are approved for Auto

Tuning, i.e. the Danfoss types VB 2 and VM 2 with

split characteristic as well as logarithmic valves

such as VF and VFS.

• The anti-bacteria function can follow a schedule

program.

• The heating circuit can have sliding DHW priority.

Communication

The ECL Comfort 210 has an ECL 485 communication

bus, which is used for closed communication

between master, slave and RCUs.

Additionally, the ECL Comfort 210 has a non-

galvanically separated RS 485 bus for limited

Modbus communication. A USB connection (type

B) can be used for an ECL Tool.

Master / slave connections

Languages

Menu languages are selectable among approx. 20

languages. See “Language list”.

Furthermore, English is always uploaded in parallel

to the selected language.
