Disposal instruction: This product should be dismantled and its components sorted, if possible, in various groups before recycling or disposal. 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.
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.

Installation 11a Mounting the ECL Comfort controller For easy access, you should mount the ECL Comfort controller near the system. Select one of the three following methods: • Mounting on a wall • Mounting on a DIN rail • Mounting in a panel Screws and rawlplugs are not supplied. Mounting on a wall Socket for mounting on wall: Order code No. 087B1149. Mount the terminal box on a wall with a smooth surface. Establish the electrical connections and position the controller in the box.

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.
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).
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.
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.
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.
17 Setting the time and date line A Actual time A 1035 Year 108 0527 Month, day Use the shift button to switch between minutes, hours, years, months and days. Set the correct time and date. Use the yellow side of the card to change the schedules. See User’s Guide, section 4. The grey side of the ECL Card Basic set-up In case of a power break, which lasts longer than 12 hours, the time and the date have to be set again. All other settings are stored as programmed.

(S3) Basic set-up Push and hold the shift button to see: - the desired DHW charging temperature - the desired DHW temperature. The activity of the motorized control valve is shown as arrows below the valve symbol. When the circulation pump is operating, it is indicated as ON below the pump symbol.

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.

29a Check list Is the ECL Comfort controller ready for use? Make sure that the correct power supply is connected to terminals 1 (Live) and 2 (Neutral). See section 12 or 13. Check that the required actuators, pumps, fans, dampers and burners are connected to the correct terminals. See sections 12 or 13. Check that all sensors are connected to the correct terminals. See section 14. Mount the controller and switch on the power. Insert the ECL Card with the yellow side facing you and push , if necessary.
29b Adapting the ECL Comfort controller to the system Turn the ECL Card so that the grey side faces you and push , if necessary. Set the time and the date (line A). See section 17. Check that all settings in the controller (sections 30 and 31) are set or that the factory settings comply with your requirements. If your system differs from the diagram shown on the cover, you should check and alter your service parameters, if necessary.
