does not contain all components that are necessary in a system.
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.

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.
The controller is pre-programmed with factory settings that are
shown in the relevant sections of this guide.
However, you might come across some settings that are not listed
in this instruction. These settings could be related either to recent
updates or the use of optional modules (which are described in
the instructions in question).
How to use this guide
This guide is divided into two parts:
• User’s Guide: Yellow sections 1-7
• Installer's Guide: Grey sections 10 and onwards
The application C67 is very flexible. These are the basic
principles:
Heating:
Typically, the flow temperature is always adjusted according to
your requirements.
The flow temperature sensors S2 (circuit I) and S4 (circuit II) are
the most important sensors. The desired flow temperatures at S2
and S4 are calculated in the ECL controller, based on the outdoor
temperature (S1). The lower the outdoor temperature, the higher
the desired flow temperature.
The motorized control valves M1 (circuit I) and M2 (circuit II) are
opened gradually when the flow temperature is lower than the
desired flow temperature and vice versa.
The return temperature, S3 (circuit I) and (if available) S5 (circuit
II) to the district heating supply should not be too high. If so,
the desired flow temperature can be adjusted (typically to a
lower value), thus resulting in a gradual closing of the motorized
control valve / valves. In boiler-based heating supply the return
temperature should not be too low (same adjustment procedure
as above).
If the measured room temperature does not equal the desired
room temperature, the desired flow temperature / temperatures
can be adjusted.
DHW:
If the measured DHW temperature is lower than the desired DHW
heating temperature minus the cut-in difference, the desired flow
temperature at S2 is increased in order to heat the DHW. DHW
heating can have priority, i.e. pump P3 is ON and the pump P1 is
OFF (or changeover valve is activated and P1 is still ON).
Before you start
Installation
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.

This means that heating circuit II cannot be supplied if heating
circuit I is deactivated.
