ECA 9010 override module Application
The override module ECA 9010 is used for the override of the clock in the ECL Comfort 200 controller (with the ECL Cards P20 and P30) as well as ECL Comfort 300 (with the ECL Cards C14, C25, C35, C37, C47, C55, C60, C62, C66, C67 and C75). The module can override periods with comfort temperature to periods with setback temperature or vice versa. The override signal can be activated by means of a normal on-off switch (make- function).
Delimitations
The function is only possible if the controller version is 1.06 or higher. The version of the controller can be seen on the back of the controller.
A vacant sensor terminal could be available in systems without a room temperature sensor S2 connected to terminal 18 or a return temperature sensor connected to terminals 20/22.
Furthermore, a vacant sensor terminal is required. Function The override function is only active if the controller mode of the ECL Comfort controller is set to scheduled operation (automatic change-over to and from periods with comfort or setback temperature)
Setting of service parameter line 141 in the ECL Comfort controller Override, sensor signal ECL Comfort 200: OFF, 1, 2, 3 or 4 ECL Comfort 300: OFF, 1, 2, 3, 4, 5 or 6 1, 2, 3, 4, 5 or 6 refer to sensors S1, S2, S3, S4, S5 or S6.
Comfort
Setback
When terminal 2 and 3 of the module is short-circuited by means of an external switch, the clock in the controller is overridden to comfort temperature, and when terminal 1 and 3 is short-circuited, the clock is overridden to setback temperature.

Constant DHW temperature control with heat exchanger
Basic principles
Constant DHW temperature control with heat exchanger or storage tank Typically, the flow temperature is adjusted according to the desired flow temperature. • Adjustment of DHW temperature If the measured DHW temperature is lower than the desired temperature, the motorized control valve is opened gradually and vice versa.
2
VD.KT.C4.02 © Danfoss 12/2012
• Return temperature limitation The return temperature to the district heating supply should not be too high. If so, the desired flow temperature can be adjusted (typically to a lower value) thus resulting in a gradual closing of the motorized control valve. In boiler-based heating supply the return temperature should not be too low (same adjustment procedure as above). • Circulation pump control The circulation pump is ON when the desired DHW temperature is higher than a userdefined value (factory setting: 20 °C).
DH-SMT/DK
Data sheet
ECL Comfort 110
Key functions
Flow temperature control • Return temperature limitation The controller automatically changes the desired flow temperature to obtain an acceptable return temperature when the return temperature falls below or gets higher than the set value. The return temperature influence can be limited by the min. / max. flow limitation. Optimization • Auto tuning A function for automatically setting the proportional band (Xp) and integration time constant (Tn).
Safety functions • Frost protection The controller automatically switches the circulation pump ON when the flow temperature is lower than a user-defined value (factory setting: 10 °C). • Motor protection The controller prevents unstable temperature control thus resulting in a longer life of the actuator. • Pump exercise Exercise of the pump to avoid blocking in periods without heat demand.

Basic principles
Control of district heating circuits with or without heat exchanger and for boiler-based heating circuits Typically, the flow temperature is adjusted according to the desired flow temperature. • Adjustment of flow temperature The desired flow temperature is calculated in the ECL Comfort controller, based on the outdoor temperature. The lower the outdoor temperature, the higher the desired flow temperature. The motorized control valve is opened gradually when the flow temperature is lower than the desired flow temperature and vice versa.

Description ECL Comfort 210 controller series
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 measure the outdoor temperature and control the flow temperature to the heating system accordingly. The weather compensated heating system increases the comfort level and saves energy. The ECL Comfort 210 controller is configured with a selected 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, adjustment of temperature according to schedule, optimization as well as limitation of return temperature, 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 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, 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 designed for mounting on wall and DIN rail. A variant ECL Comfort 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 front of the panel. The ECL Comfort 210 is a stand-alone controller which communicates with the RCU and other ECL Comfort 210 / 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 and override of the ECL Comfort 210. 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).

Functions
General functions: • The ECL Comfort 210 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 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 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 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).
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. • 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 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 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 schedule program. • The heating circuit can have sliding DHW priority.
The ECL Comfort 210 has an ECL 485 communication bus, which is used for closed communication between master, slave and RCUs. Additionally, the ECL Comfort 210 has a nongalvanically separated RS 485 bus for limited Modbus communication. A USB connection (type B) can be used for an ECL Tool.

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 control 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.

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.
