[. . . ] Necessary assembly, start-up, and maintenance work must be performed by qualified and authorized personnel only. This guide is associated with ECL Card 087B4974 Installer: By: Date: The shown diagram is a fundamental and simplified example and does not contain all components that are necessary in a system. = Closes If the system you are about to install differs from the shown diagram of a standard heating system, feel free to sketch an outline for comparison. Adaptation of systems, see section 10.

Please note that the room panel / remote control is only active if the system device bus is active. The bus is active when the outdoor temperature sensor is connected. 0 Line Value 10 Range indicator Now you can move to any line of your choice. Choose between 0: Room temperature sensor (no room panel / remote control) 1: Room panel ECA 60 / 62 or remote control ECA 61 / 63 with address A 2: Room panel ECA 60 / 62 or remote control ECA 61 / 63 with address B 3 . . . You can select any of the two circuits no matter what line you are in. You will not necessarily enter the same line number. This is done by integrating the difference and adjusting the desired flow temperature. 1: 30: The desired temperature is adapted quickly. The desired temperature is adapted slowly.

I ON / OFF Decide whether you want a total stop during the setback temperature period. OFF: The desired flow temperature in circuit I is not influenced by any other controller (slave or circuit II). 20: The desired flow temperature is increased by the set value (line 17), if the demand of a slave / circuit II is higher. Temp. Setting line 17 ON: The desired flow temperature is lowered to 10 °C. setting of the flow temperature (line 2, section 22) is overruled. Desired flow temp. (°C) Tflow. ref(I) 10 °C Tflow. ref(II) Time Time OFF: No total stop Desired flow temp. (°C) Example: If a slave controller (or circuit II) demands a higher temperature than that of the master controller (Tflow. ref(I)), the temperature of the master will be increased accordingly (Tflow. ref(II)) + the setting (line 17). The function of line 17 can compensate for heat losses between master and slave controlled systems. 10 °C Extended service Extended service 20 Optimization based on room / outdoor temperature Circuit Setting range Factory setting I ON / OFF OFF The optimized start and stop time can be based on either room or outdoor temperature. Time ON: Optimization based on room temperature, if measured. OFF: Optimization based on outdoor temperature. Use this setting if the room temperature is not measured.

Circuit Setting range II 10 . . . 110 °C 50 °C Set the return temperature you accept for the heating / DHW circuit. ON: The pump is switched ON for 1 minute every third day around noon. Set the acceptable return temperature limit. [. . . ] In the DHW circuit, however, the DHW temperature is controlled according to the setback temperature. The setting of the desired room temperature is important even if a room temperature sensor / room panel / remote control is not connected. 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.
