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.
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.
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.
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.
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.
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)
ECL Comfort 310 controller, Remote Control Units ECA 30 / 31 and Application keys
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.

DEN-SMT/DK
ECL Comfort 310 controller, Remote Control Units ECA 30 / 31 and Application keys
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.
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:
·
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.
