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 C37 is very flexible. These are the basic
principles:
Heating:
Typically, the flow temperature is always adjusted according to
your requirements.
The flow temperature sensor (S3) is the most important sensor.
The desired flow temperature at S3 is 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 valve (M1) is opened gradually when the
flow temperature is lower than the desired flow temperature and
vice versa.
The return temperature (S4) 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. 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 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 S3 is increased in order to heat the DHW. DHW
heating can have priority, i.e. pump P2 is ON and 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.

Installation
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. Secure the controller with the fixing
screw.
Mounting on a DIN rail
Mounting kit: Order code No. 087B1145.
A mounting kit is necessary to mount the box with the
controller on a DIN rail.
Mounting in a panel
Connector set: Order code No. 087B1148.
The panel plate thickness must not exceed 3 mm.
Prepare a cut-out with the dimensions 93 x 139 mm. Pull off
the right side of the lid by means of a screwdriver.
Insert the controller into the panel cut-out and fix it with the
two locks which are placed diagonally in two corners of the
controller.
