Table of Contents Sections in the Installer’s Guide The documentation for the ECL Comfort controller is composed of numbered sections. Only sections relevant to your ECL Comfort controller are included here. Before you start Installation 10 11 12 14 15 Identifying the system type Mounting the ECL Comfort controller Electrical connections 230 V a.c.
Before you start Sketch your application The ECL Comfort controller series is designed for a wide range of heating, hot-water 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 1.08.

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.
