Description

ECL Comfort 210 controller
series

ECL Comfort 210

The ECL Comfort 210 is an electronic weather
compensated temperature controller in the ECL
Comfort controller family for use in district heating,
central heating and cooling systems. Energy savings
can be achieved by correct control of the flow tem­perature in heating and cooling systems. Up to 3
circuits can be controlled. The weather compen­sation function in the ECL Comfort controllers
measures the outdoo r temperature and controls the
flow temperature to the h eating system accordingly.
The weather compe nsated heating system increases
the comfort level and saves energy.
The ECL Comfort 210 controller is configured with a
selecte d application by means of an ECL application
key.

ECL Comfort 210 is designed for comfortable
temperatures, optimum energy consumption, easy
installation by means of the ECL application key
(plug-and-play) and user friendly operation.
Improved energy savings are facilitated by weather
compensation, a djustment of temperature according
to schedule, optimization as well as limitation of
return temperat ure, flow and power. Functionalities
such as data logging and alarm functions are
implemented in the controller.

The ECL Comfort 210 is easily operated by means of
a dial (multi-functional knob) or a Remote Control
Unit (RCU). The dial and the backlighted display
guide the user through the text menus in the
selected language.

The ECL Comfort 210 controller has elec tronic output
for motorized valve control (3-point control), relay
outputs for circulation pump / changeover valve
control among others, as well as alarm output.

6 Pt 1000 temperature sensors can b e connected. In
addition, 2 inputs are configured when uploading
the application. The configuration can be Pt 1000
temperature sensor input, analog input (0 – 10 V) or
digital input.

The enclosure is desi gned for mounting on wall and
DIN rail. A variant ECL Comfo rt 210B (without display
and dial) is available. It can be used for mounting
inside a panel and is operated by means of the RCU
ECA 30 / 31 which can be placed in fro nt of the panel.

The ECL Comfort 210 is a stand-alone controller
which communicates with the RCU and other ECL
Comfort 210 / 296 / 310 controllers via the ECL 485
communication bus.

Remote Control Unit (RCU):

The RCUs ECA 30 and ECA 31 are used for room
temperature control a nd override of the ECL Comfort

210. The display has backlight. The RCUs are
connected to the ECL Comfort controll ers by means
of 2 × twisted pair cable for communication and
power supply (ECL 485 communication bus).

The ECA 30 / 31 has a built-in room temperature
sensor. An external room temperature sensor can
be connected substituting the built-in temperature
sensor. Furthermore, the ECA 31 has a built-in
humidity sensor and the relative humidity signal is
used in relevant applications. It is possible to
connect up to 2 RCUs on th e ECL 485 communication
bus. One RCU can monitor max. 10 ECL Comfort
controllers (master / slave system).

Description (continued) ECL application key and applications:

Different ECL application keys make it easy for the
ECL Comfort 210 hardware to run different
applications. The ECL Comfort 210 controller is
loaded with the desired application by means of
the ECL application key, which contains
information about applications (simple
application sketches are shown in the display),
languages, factory settings and firmware.

The ECL application keys for ECL Comfor t 210 can
also be used in ECL Comfort 296 / 310.

The relevant ECL application keys for the ECL
Comfort 210 controller can be found in the
ordering section.

For information, ECL Comfort 296 and ECL Comfort
310 have built-in M-bus communication and TCP/
IP connection for internet in order to connect to
the ECL Portal.

Furthermore, ECL Comfort 310 can be equipped
with extension mo dule ECA 32 for control of 0 - 10
Volt (modulated) controlled actuators.

The application parameters are stored in the
controller and are not affected by power break.

Application examples All mentioned components (S = temperature sensor, P = pump, M = Motorized control valve and so

on) are wired to the ECL Comfort 210.
