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.

Functions General functions:

• The ECL Comfort 210 has all the required functions of a modern electronic temperature controller for heating, cooling, ventilation and DHW applications.

• The controller can be used as master or slave in systems with master / slave ECL Comfort 210 / 296 / 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 210 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 can be 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 comfor t or saving mode.

• The ECL Comfort 210 can receive pulses from a heat or ﬂow meter to limit the power or the ﬂow.

• In many applications analog 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).

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 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 210 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 can be 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 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.

• T he anti-bacteria function c an follow a dedicated schedule program.

• The heating circuit can have sliding DHW priority.
