Mixing controller with PI controlled DHW

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 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, 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 F66 is very exible. These are the basic principles:
Heating:
Typically, the ow temperature is adjusted according to your
requirements.
The ow temperature sensor (S3) is the most important sensor.
The desired ow temperature at S3 is calculated in the ECL
controller, based on the outdoor temperature (S1). The lower the
outdoor temperature, the higher the desired ow temperature.
The motorized control valve (M1) is opened gradually when the
ow temperature is lower than the desired ow temperature and
vice versa.
The return temperature (S4) to the district heating supply should
not be too high. If so, the desired ow 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 ow temperature can be adjusted.
DHW:
If the measured DHW temperature (S5) is lower than the desired
DHW temperature, the motorized control valve (M2) is opened
gradually and vice versa.
If the desired DHW temperature cannot be reached, the heating
circuit can be closed gradually.

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 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 Indirectly connected heating system and DHW
circuit
System settings
Check that the setting in line 24, gear motor / thermo actuator,
is set correctly in both circuits.
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.
