Always follow the local disposal regulations. Before you start Sketch your application The ECL Comfort controller series is designed for a wide range of heating, domestic hot-water (DHW) and cooling systems with different configurations and capacities. If your system differs from the diagrams shown in section 10, you may want to make a sketch of the system about to be installed. This makes it easier to use the Installer’s Guide, which will guide you step-by-step from installation to final adjustments before the end-user takes over. The controller is pre-programmed with factory settings that are shown in the relevant sections of this guide. However, you might come across some settings that are not listed in this instruction. These settings could be related either to recent updates or the use of optional modules (which are described in the instructions in question). How to use this guide This guide is divided into two parts: • User’s Guide: Yellow sections 1-7 • Installer's Guide: Grey sections 10 and onwards The application C17 is very flexible. These are the basic principles: Typically, the tank temperature (S6) is adjusted according to your requirements. The charging temperature sensor (S2) is the most important sensor. The desired charging temperature at S2 is set in the ECL controller (line C, yellow side). If the measured DHW temperature (S6) is lower than the desired charging temperature minus the cut-in difference, charging starts. The charging pump, P2, is switched ON. When the measured DHW temperature (S5) is higher than the desired charging temperature minus the cut-out difference, charging stops. The motorized control valve (M1) is opened gradually when the charging temperature is lower than the desired charging temperature and vice versa. Typically, the return temperature (S4) to the district heating supply should be as low as possible. If not so, the desired charging temperature can be adjusted. The S1 temperature can correct the proportional band (Xp). Typically, the Xp must be increased at a rising S1 temperature. VI.KT.O1.02 Card C17 2008.07 The S3 temperature gives a feedback to the DHW charging temperature (S2). If the S3 temperature is too low, the desired temperature at S2 will be increased. Installation 10a Identifying the system type The ECL Comfort controller is a universal controller that can be used for various systems. Based on the shown standard systems, it is possible to configure additional systems. In this section you find the most frequently used systems. If your system is not quite as shown below, find the diagram which has the best resemblance with your system and make your own combinations. The functions can only be realized with ECL Comfort 300 and as of controller version 1.08. 10.1 Full installation, external DHW circulation 10.2 Full installation, internal DHW circulation System diagrams in this instruction are principal drawings and do not contain all components which are necessary in your systems. 10b 10.3 Minimum installation Installation 10.4 Minimum installation, district heating System diagrams in this instruction are principal drawings and do not contain all components which are necessary in your systems.

Wire cross section for sensor connections: Min. 0.4 mm2 Total cable length:Max. 125 m (all sensors incl. system device bus) Cable lengths of more than 125 m may cause noise sensibility (EMC). 14b The temperature sensor mentioned below are sensors used for the ECL Comfort 200 and 300 series which not all will be needed for your application! Outdoor temperature sensor (ESMT) The outdoor sensor should be mounted on that side of the building where it is less likely to be exposed to direct sunshine. It should not be placed close to doors, windows or air outlets. Flow temperature sensor (ESMU, ESM-11 or ESMC) Place the sensor max. 15 cm from the mixing point. In systems with heat exchanger, Danfoss recommends that the ESMU-type to be inserted into the exchanger flow outlet. Make sure that the surface of the pipe is clean and even where the sensor is mounted. Return temperature sensor (ESMU, ESM-11 or ESMC) The return sensor should always be placed in / on a pipe with return water flow. Room temperature sensor (ESM-10, ECA 60 / 62 room panel or ECA 61 / 63 remote control) Place the room sensor in the room where the temperature is to be controlled. Do not place it on outside walls or close to radiators, windows or doors. DHW temperature sensor (ESMU or ESMB-12) Place the DHW temperature sensor according to the manufacturer’s specification. Boiler temperature sensor (ESMU, ESM-11 or ESMC) Place the sensor according to the boiler manufacturer’s specification. Flow / air duct temperature sensor (ESM-11, ESMB-12, ESMC or ESMU types) Place the sensor so that it measures a representative temperature. Slab temperature sensor (ESMB-12) Place the sensor in the slab. Valid for ESM-11: Do not move the sensor after it has been fastened in order to avoid damage to the sensor element. Installation It is important that the sensors are mounted in the correct position in your system. 14c Installation Override For an active override, you have to choose the mode “scheduled operation”! Input S1 ... S6 (ECL Card C14 only uses S5) can be used for override purposes (section 32, line 141). Connection example without ECA 9010 If the override switch has goldplated contacts, you can choose one of the following solutions or a combination of both: (C14 = 21 only) (C14 = 21 only) Closed switch: Comfort temperature Closed switch: Setback temperature Open switch: Scheduled operation Open switch: Scheduled operation Connection example with ECA 9010 The ECA 9010 module is powered by the system device bus, which means that the bus must be active. The bus is activated by setting the controller address to 15 (line 199). To avoid influence from contact resistance, the use of ECA 9010 is recommended. Red Brown Green S1 ... S6 (C14 = S5 only) Comfort Saving 14c Installation Inserting the ECL Card Installation 15a How to insert your ECL Card the first time After the power has been switched on, open the lid on the front side of the controller. Place the ECL Card with the yellow side facing you. This enables the controller to read the ECL Card data. The controller immediately starts to copy the application type and factory settings from the ECL Card. After copying, the display will show you the application type. After approx. 10 sec. the display will change to display line C. Display example: CPY 0 Software version, ECL Card Line Circuit Time Outdoor temp. C99 Application type C37 05 Software version, controller 109 C 1835 3 0 3 20 6 9 12 15 18 21 Desired room temp. 24 The controller is now ready to be set to control your system. If the display keeps showing CPY, see section 34b. 15b The ECL Card contains factory settings for a standard system. If the actual system differs from the standard system, the controller must be adjusted accordingly. After the adjustment, the new settings should be stored on the ECL Card. For ECL Card copying and daily use including adjustment of temperatures and schedules, insert the ECL Card with the yellow side facing you. For system set-up adjustments, the grey side of the ECL Card - the installer’s side - must be facing you. As a main rule, the ECL Card should always remain in the controller during service, maintenance and setting. If the card is removed or left in the controller with the grey side facing you, please note that: • After approx. 25 min.: - The controller cannot be operated. - The controller reverts to display C (section 1). • The ECL Card must not be exposed to direct heat or sunshine. If several controllers are installed in the system you can write a title on the ECL Card with a permanent ink pen. Do not remove the ECL Card while copying. The data on the ECL Card can be damaged! When you store your personal settings on your ECL Card, the factory settings will be overridden. Installation Understanding the ECL Card 16 Adjusting the ECL Card settings General principles When the controller is connected and operating you can check and adjust all or some of the basic settings. Turn the ECL Card so that the grey side is facing you (see the example below). Use the arrow buttons to move from line to line of the ECL Card, for example line 2: 1 ON Basic set-up Circuit Line 1 2 2 ON 3 ON 2 Setting to be adjusted 40 90 Value in range indicator Use the plus / minus buttons to adjust the settings. In some displays more than one setting or value can be adjusted. Use the shift button to switch between the options. The circuit selector shifts between circuit I and II. You can adjust all settings and service parameters individually. Update of the ECL Card after maintenance and service All new settings can be stored on the ECL Card.

OFF or ON when The motorized actuator (gear motor) closes or opens the controlled unit as long as the relevant button is pushed. If pushed for more than 3 seconds, the actuator continues to close or open the valve. The thermo actuator activates the valve as long as the button is pushed. If pushed for more than 3 seconds, the actuator continues to open the valve. Check the activation direction of the actuator either by looking at it or by feeling whether the temperature of the actual pipe changes as expected. This operation applies to both circuits, if available. During manual operation, all control functions are deactivated.

Set a long integration time to obtain a slow but stable reaction to deviations. A short integration time will make the controller react fast but with less stability 6 Running time of the motorized control valve Circuit Setting range Factory setting I 5 ... 250 sec. 35 sec. Set the running time of the motorized control valve according to the example. This is the time it takes the controlled unit to move from fully closed to fully open position. How to calculate the running time of a motorized control valve The running time of the motorized control valve is calculated using the following methods: Seated valves Running time = Valve stroke (mm) x actuator speed (sec. / mm) Example: 5.0 mm x 15 sec. / mm = 75 sec. Rotating valves Running time = Turning degrees x actuator speed (sec. / degr.) Example: 90 degrees x 2 = 180 sec. The grey side of the ECL Card 26b 7 Neutral zone, Nz Circuit Setting range Factory setting I 0 ... 9 K 3K Set the neutral zone to a high value if you can accept a high variation in flow temperature. When the actual flow temperature is within the neutral zone, the controller does not activate the motorized valve. Control parameters (lines 4-7) are overruled if thermo actuator is chosen (OFF). If you want to tune the PI regulation precisely, you can use the following method: • Set the integration time (line 5) to its max. value (999 sec.). • Decrease the value for the proportional band (line 4) until the system starts hunting with a constant amplitude (it might be necessary to force the system by setting an extreme value). • Find the critical time period on the temperature recording or use a stop watch. Temp. Critical time period Time This time period will be characteristic for the system, and you can evaluate the settings from this critical period. Integration time = 0.85 x critical time period Proportional band = 2.2 x proportional band value in the critical time period. If the regulation seems to be too slow, you can decrease the proportional band value by 10%. Make sure there is a consumption when you set the parameters. The grey side of the ECL Card Basic set-up The neutral zone is symmetrical around the desired flow temperature value, i.e. half the value is above and half the value is below this temperature. 27a Cut-in and cut-out temperature at DHW charging - lines 1-2 The controller can control the DHW temperature with either one or two tank temperature sensor(s). The controller will automatically register the number of sensors. 1 Cut-out temperature difference - (lower sensor)* Circuit Setting range Factory setting I 1 ... 99 K 15 K Set the difference between the desired charging temperature and cut-out temperature (charging stop) . Basic set-up Set the difference. Example: Desired charging temperature (section 3): 60 °C Cut-out difference: 15 K Calculated cut-out temperature (60-15) = 45 °C 2 Cut-in temperature difference - (upper sensor)* Circuit Setting range Factory setting I 1 ... 99 K 20 K Set the difference between the desired charging temperature and cut-in temperature (charging start). Set the difference. Example: Desired charging temperature (section 3): 60 °C Cut-in difference: 20 K Calculated cut-in temperature (60-20) = * In case of two sensors.

Circuit Setting range Factory setting I -9.9 ... 0 ... 9.9 0.0 Set the influence from the return temperature on the desired DHW charging temperature. Set the influence of the max. return temperature (set in line 30). Influence higher than 0: The desired DHW charging temperature is increased, when the return temperature gets higher than the set limit. Influence lower than 0: The desired DHW charging temperature is decreased, when the return temperature gets higher than the set limit. Influence 0 Max. limitation > 0 Limit Max. limitation < 0 Return temp. Example The limitation temperature is set to 25 °C. The influence is set to -2.0. The actual return temperature is 2 degrees too high. Extended service Result: The desired DHW charging temperature is changed by -2.0 x 2 = -4 degrees.

Miscellaneous The yellow side of the ECL Card 7a Definitions Air duct temperature Temperature measured in the air duct where the temperature is to be controlled. Balance temperature This setpoint is the basis for the flow / air duct temperature. The balance temperature can be adjusted by the room temperature, the compensation temperature and the return temperature. The balance temperature is only active if a room temperature sensor is connected. Comfort operation Normal temperature in the system controlled by the schedule. During heating the flow temperature in the system is higher to maintain the desired room temperature. During cooling the flow temperature in the system is lower to maintain the desired room temperature. Comfort temperature Temperature maintained in the circuits during comfort periods. Normally during daytime. Compensation temperature A measured temperature influencing the flow temperature reference / balance temperature. Controller mode indicator Black arrow to the right of the symbols indicating the present mode. Desired room temperature Temperature which is set as the desired room temperature. The temperature can only be controlled by the ECL Comfort controller if a room temperature sensor is installed. If a sensor is not installed, the set desired room temperature however still influences the flow temperature. In both cases the room temperature in each room is typically controlled by radiator thermostats / valves. Desired temperature Temperature based on a setting or a controller calculation. Dew point temperature Temperature at which the humidity in the air condensates. Factory settings Settings stored on the ECL Card to simplify the set up of your controller the first time. Flow temperature Temperature measured in the flow at any time. Flow temperature reference Temperature calculated by the controller on basis of the outdoor temperature and influences from the room and / or return temperatures. This temperature is used as a reference for the control. Heating circuit The circuit for heating the room / building. Heating curve A curve showing the relationship between actual outdoor temperature and required flow temperature. DHW circuit The circuit for heating the domestic hot water (DHW). 7b Humidity, relative This value (stated in %) refers to the indoor moisture content compared to the max. moisture content. The relative humidity is measured by the ECA 62 / 63 and is used for the calculation of the dew point temperature. Limitation temperature Temperature that influences the desired flow / balance temperature. Pt 1000 sensor All sensors used with the ECL Comfort controller are based on the Pt 1000 type. The resistance is 1000 ohm at 0 °C and it changes with 3.9 ohm / degree. Optimization The controller optimizes the start time of the scheduled temperature periods. Based on the outdoor temperature, the controller automatically calculates when to start in order to reach the comfort temperature at the set time. The lower the outdoor temperature, the earlier the start time. Return temperature The temperature measured in the return influences the desired flow temperature. Room temperature sensor Temperature sensor placed in the room (reference room, typically the living room) where the temperature is to be controlled. Room temperature Temperature measured by the room temperature sensor, room panel or remote control. The room temperature can only be controlled directly if a sensor is installed. The room temperature influences the desired flow temperature. Schedule Schedule for periods with comfort and setback / saving temperatures. The schedule can be made individually for each week day and may consist of up to 3 comfort periods per day. Setback / saving temperature Temperature maintained in the heating / DHW circuit during setback temperature periods. State / mode indicators White arrow to the left of the symbols (sun / moon). The white arrow indicates the present state, comfort (sun) or setback / saving (moon), when the controller is in scheduled operation mode. The black arrow symbol indicates the mode of the controller. Time line / bar Line with numbers representing the hours. Below the time line, time bars represent scheduled periods with comfort temperature. The bar is divided into half hour sections. Weather compensation Flow temperature control based on the outdoor temperature. The control is related to a user-defined cooling curve. The definitions apply to the Comfort 200 as well as ECL Comfort 300 series. Consequently, you might come across expressions that are not mentioned in your guide. 6a Hot points The time shown in the display is one hour off? See the summer time changeover in line 198, section 32. The time shown in the display is not correct? The internal clock may have been reset, if there has been a power break for more than 12 hours.

Order a replacement from your Danfoss representative. Insert the new ECL Card with the yellow side facing you and make sure that you copy your personal settings from the controller to the ECL Card. See section 34. The room temperature is too low? Make sure that the radiator thermostat does not limit the room temperature. If you still cannot obtain the desired room temperature by adjusting the radiator thermostats, the flow temperature is too low. Increase the desired room temperature (section 3). If this does not help, adjust the heating curve / balance temperature (section 20). The room temperature is too high during saving periods? Make sure that the max. flow temperature limitation is not too low. See section 22. The temperature is unstable? Check that the flow temperature sensor is correctly connected and in the right place. Adjust the control parameters (section 26). If the controller has a room temperature signal, see section 23. The controller does not operate and the control valve is closed?
