How to identify your 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.
Heating system 1:
District heating circuit with heat exchanger
Heating system 2:
Boiler-based heating circuit

How to determine another heat curve, if necessary:
Choose the calculated flow temperature for your system and the determined min.
outdoor temperature for your area. Pick the heat curve closest to the crossing point of
these two values.
The setting of the desired room temperature has an influence on the calculated flow
temperature (heat curve), no matter if a room temperature sensor is connected or not.
Floor heating systems
This controller is factory set for radiator systems, which typically are high flow temperature
systems. To control floor heating systems, which typically are low flow temperature systems,
you need to change the ‘Slope’ according to your type of system (typical setting: 1.0).
