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.

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 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.

10b

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.
