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 be increased and/or service costs reduced. The heating and/or cooling installation is made accessible from virtually 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 sensors 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 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. |
|
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. |
|
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. |
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 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 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.
