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, 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 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 301 and as of controller version 2.00. 10.
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.

14a 14b Connecting and placing the temperature sensors It is important that the sensors are mounted in the correct position in your system. 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.
14c Installation Installation Connecting the room panel / remote control The ECA 60 / 61 / 62 / 63 is activated by the setting in line 10 (section 32). The ECA 60 / 61 / 62 / 63 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 (section 32, line 199). Override For an active override, you have to choose the mode “scheduled operation”! Input S1 ...
15a 15b Inserting the ECL Card Installation 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.

Copy personal settings to additional controller(s) in identical systems Insert the ECL Card with the yellow side facing you. Ensure that the other controller(s) use(s) the same ECL Card type. (If this is not the case, please read section 15). Go to line 8 (is not displayed), which is the first line below line 7.
7a 7b Definitions Air duct temperature Humidity, relative Temperature measured in the air duct where the temperature is to be controlled. 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. Balance temperature This setpoint is the basis for the flow / air duct temperature.
