Description
ECL Comfort 310 controller
series
The ECL Comfort 310 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 4 circuits can be controlled.
The weather compensation function in the ECL
Comfort controllers measures the outdoor
temperature and controls the flow temperature
to the heating system accordingly. The weather
compensated heating system increases the
comfort level and saves energy.
The ECL Comfort 310 controller is configured with
a selected application by means of an ECL
Application Key.
The web based ECL Portal communicates with the
ECL Comfort 310 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 be
increased and/or service costs reduced. The
heating and/or cooling installation is made
accessible from virtually anywhere at any time via
laptops or Smartphones which increases service
level and reduces response time to alarms.
The ECL Tool software for ECL Comfort 310 offers
possibilities for an alternative remote control in
relation to ECL Portal and OPC server software.

ECL Comfort 310 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, adjustment of
temperature according to schedule, optimization
as well as limitation of return temperature, flow
and power.
The ECL Comfort 310 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 310 controller has electronic
output for motorized valve control, relay output
for circulation pump / changeover valve control
among others, as well as alarm output.
6 Pt 1000 temperature sensors can be connected.
In addition, 4 inputs are configured when
uploading the application. The configuration can
be Pt 1000 temperature sensor input, analogue
input (0 – 10 V) or digital input.
Depending on application, the internal extension
module ECA 32 (inserted into the controllers base
part) can give additional input and output signals.

Description (continued)
The enclosure is designed for mounting on wall
and DIN rail. A variant ECL Comfort 310B (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 front
of the panel.
The ECL Comfort 310 can work as a stand-alone
controller and communicate with up to two RCUs
and an extension module ECA 32 with additional
inputs / outputs.
The ECL Comfort 310 can also work with up to 2 x
RCUs, ECA 32 and other ECL Comfort 210 / 310
controllers via the ECL 485 communication bus.
Ethernet connection 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.
Remote Control Unit (RCU):
The RCUs ECA 30 and ECA 31 are used for room
temperature control and override of the ECL
Comfort 310. The display has backlight. The RCUs
are connected to the ECL Comfort controllers 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 relative
humidity sensor and the 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 Application Key and applications:
Different ECL Application Keys make it easy for the
ECL Comfort 310 hardware to run different
applications. The ECL Comfort 310 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 and
factory settings.
The ECL Application Keys, series A2xx can be used
in ECL Comfort 210 and ECL Comfort 310. Most of
the A2xx application keys give extended
functionalities when used in ECL Comfort 310, such
as additional temperature sensors and M-bus
communication.
The ECL Application Keys, series 3xx can be used
in ECL Comfort 310 only.
The application parameters are stored in the
controller and are not affected by power break.
The relevant ECL Application Keys for the ECL
Comfort 210 / 310 controller can be found in the
ordering section.

The graphical monochrome display (A) shows all
temperature values as well as status information
and is used for the setting of control parameters.
The display has backlight. Different favorite
displays can be selected. Navigation, browsing
and selecting the current item in the menus is
done by means of the dial (multi-functional knob
(B)).
The RCUs ECA 30 / 31 are used for remote setting
and override of ECL Comfort controller. By means
of the built-in room temperature sensor, the flow
temperature can be corrected to keep a constant
room temperature at comfort or saving
temperature. The ECA 30 / 31 is operated as an ECL
Comfort 310 with dial and backlighted display.

ECL Comfort 310 controller, Remote Control Units ECA 30 / 31 and Application keys
Functions
General functions:
•The ECL Comfort 310 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 flexible configuration. Furthermore,
an update of the controller software is done
automatically, if required.
•The ECL Comfort 310 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 310 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).
•Motorized control valves in some applications
can be controlled with a 0 - 10 V signal.
•Several applications fulfil the demand for refill
water function and / or 2-pump control.
Communication
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.
In some application sub-types (for example A337,
A347, A367, A375 and A377) the desired flow
temperature can be set by means of a voltage in
the range 0 - 10 volt.
•The return temperature limitation can work in
relation to the outdoor temperature or be a fixed
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
310 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 fixed
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 application
A217, A266, A368 and A376. 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.
The ECL Comfort 310 has:
• ECL 485 bus, non-galvanic isolated, for 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).
• Ethernet, RJ 45, for TCP communication to
SCADA systems.
