Description
ECL Comfort 296
controller series
ECL Comfort 296 controller:
The ECL Comfort 296 is an electronic weather
compensated temperature controller in the ECL
Comfort controller family for use in district
heating, central heating, cooling and ventilation
systems.
Energy savings can be achieved by correct control
of the flow temperature in heating and cooling
systems. The controller has 2 control circuits and
one additional thermostatic function.
The weather compensation function in the ECL
Comfort controllers measures the outdoor
temperature and controls the flow temperature
to the heating system accordingly. In case it is
available it also controls the domestic hotwater
installation.
The weather compensated heating system
increases the comfort level and saves energy.
The ECL Comfort 296 controller is configured with
a selected application by means of an ECL
Application Key.
The web-based ECL Portal communicates with
the ECL Comfort 296 controller for an effective
and easy-to-use turnkey SCADA (Supervisory
Control And Data Acquisition) tool for all users,
service personnel and at commissioning.
Service level can b e increased and/or service costs
reduced. The heating and/or cooling installation
is made accessible from vir tually anywhere at any
time via i.e. laptops or Smartphones which
increases service level and reduces response time
to alarms.
The ECL Tool software for ECL Comfort 296
controller offers possibilities for an alternative
remote control in relation to the ECL Portal and
OPC server software.
The ECL Comfort 296 controller is designed for
comfortable temperatures, optimum energy
consumption, easy installation by means of the
ECL Application Key (Plug-and-Play) and userfriendly operation.
Improved energy savings are facilitated by
weather compensation, adjustment of
temperature according to schedule, optimization
as well as limitation of return temperature, flow
and power.
The ECL Comfort 296 controller 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 296 controller has electronic
output for motorized valve control, relay output
for circulation pump / changeover valve control
among others, as well as alarm output.
Six Pt 1000 temperature se nsors can be connected.
In addition, two inputs are configured when
uploading the application. The configuration can
be Pt 1000 temperature sensor input, analogue
input (0 – 10 V) or digital input.

Description (continued)
The enclosure is designed for panel mounting, on
a wall and DIN rail.
The ECL Comfort 296 can work as a stand-alone
controller and communicate with up to two RCUs.
The ECL Comfort 296 can also work with other ECL
Comfort 296 / 210 / 310 controllers via the ECL 485
communication bus.
Ethernet connec tion is integrated in the controller.
Furthermore, Modbus communication to SCADA
systems (Supervisory Control And Data
Acquisition) and M-bus communication to heat
meters are integrated.
ECL Application Key and applications:
Different ECL Application Keys make it easy for
the ECL Comfort 296 hardware to run different
applications. The ECL Comfort 296 controller is
loaded with the desired application by means of
the ECL Application Key, which contains
information about applications (basic application
sketches are shown in the display), languages,
factory settings and firmware.
The ECL Application Keys, series A2xx can be used
in the ECL Comfort 296.
Remote Control Unit (RCU):
The RCUs ECA 30 and ECA 31 are used for room
temperature control and override of the ECL
Comfort 296. The display has backlight. The RCUs
are connected to the ECL Comfort controllers by
means of 2 × twisted p air 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 the ECL 485 communication bus.
One RCU can monitor max. 10 ECL Comfort
controllers (master / slave system).
ECL 296 controls 3-point based actuators:
If need for control of 0 - 10 Volt based actuators,
the ECL 310 and extension module ECA 32 or ECA
35 is recommended for dedicated applications.
Here the 0 - 10 Volt signal comes from the
extension module.
The application parameters are stored in the
controller and are not affected by power break.
The relevant ECL Application Keys for the ECL
Comfort 296 controller can be found in the
ordering section.
In addition to the above selected application keys
can run and log a temperature / time controlled
floor (screed) drying process for floor heating
applications.

ECL Comfort 296 controller, Remote Control Units ECA 30 / 31 and Application Keys
Functions General functions:
• The ECL Comfort 296 has all the required
functions of a modern electronic temperature
controller for heating, cooling and DHW
applications.
• The controller can be used as master or slave
in systems with master / slave ECL Comfort
296 / 210 /310 controllers.
• The ECL Application Key contains the
application software for flexible configuration.
Furthermore, an update of the controller
software is done automatically, if required.
• The ECL Comfort 296 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.
• If applicable in the application key the ECL
Comfort 296 can receive pulses from a heat or
flow meter to limit the power or the flow.
Alternatively, the data can come from heat or
flow meter via the M-bus connection.
• In many applications analogue input (0 – 10 V)
is configured for pressure measuring among
others. The scaling is set in the controller.
• Some applications are configured to handle
digital input. This function can be used to
have an external switch to run comfort or
saving mode or react on a flow 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).
• Dedicated applications fulfil the demand for
refill water function and / or 2-pump control.
Heating functions:
• The heat curve (relationship between outdoor
temperature and desired flow temperature) is
set by means of 6 coordinate points or a slope
value. Max. / min. limitation of the desired
flow temperature can be set.
• The return temperature limitation can work in
relation to the outdoor temperature or be a
set 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 296 can correct the desired flow
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 flow temperature with set
reduction or reduction in relation to outdoor
temperature (the lower the outdoor
temperature, the less the reduction),
· heating off, 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
applications 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 week
schedule.
• The DHW circuit can have full or sliding
priority.
Communication The ECL Comfort 296 has:
• ECL 485 bus, non -g alvanic isolated, f or closed
communication between master, slave and
RCUs.
• RS 485 bus, galvanic isolated, for Modbus
communication.
• M-bus, non-galvanic isolated, for M-bus
communication with meters.
• USB, type B, for ECL Tool (software for PC /
laptop).
• Ethernet, RJ 45, for TCP/IP communication to
Internet (ECL Portal) and SCADA systems.
Languages Most application keys contain up to 22
languages. See language list.
