Domestic hot-water (DHW) controller

The shown diagram is a fundamental and simplied example and
does not contain all components that are necessary in a system.
If the system you are about to install diers from the shown
diagram of a standard 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, domestic hot-water (DHW) and cooling
systems with dierent congurations and capacities.
If your system diers 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 nal
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 C17 is very exible. These are the basic principles:
Typically, the tank temperature (S6) is adjusted according to your
requirements. The charging temperature sensor (S2) is the most
important sensor. The desired charging temperature at S2 is set in
the ECL controller (line C, yellow side).
If the measured DHW temperature (S6) is lower than the desired
charging temperature minus the cut-in dierence, charging
starts. The charging pump, P2, is switched ON.
When the measured DHW temperature (S5) is higher than the
desired charging temperature minus the cut-out dierence,
charging stops.
The motorized control valve (M1) is opened gradually when the
charging temperature is lower than the desired charging
temperature and vice versa.
Typically, the return temperature (S4) to the district heating
supply should be as low as possible. If not so, the desired
charging temperature can be adjusted.
The S1 temperature can correct the proportional band (Xp).
Typically, the Xp must be increased at a rising S1 temperature.
The S3 temperature gives a feedback to the DHW charging
temperature (S2). If the S3 temperature is too low, the desired
temperature at S2 will be increased.

Installation
Identifying the system type
10a
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 congure additional systems.
In this section you nd the most frequently used systems. If
your system is not quite as shown below, nd 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.
10.1 Full installation, external DHW circulation
10.2 Full installation, internal DHW circulation
System diagrams in this instruction are principal drawings and do
not contain all components which are necessary in your systems.

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 xing
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 o
the right side of the lid by means of a screwdriver.
Insert the controller into the panel cut-out and x it with the
two locks which are placed diagonally in two corners of the
controller.
