Before you start

How to use this guide

This guide is divided into two parts:

• Daily Use (turn the guide over)

Yellow sections 01 - 09

• Installation and maintenance:

Grey sections 10 and onwards

Save energy - save money - improve your comfort

temperature

The ECL Comfort controller is designed by Danfoss for

temperature control of heating systems.

The ECL Comfort controller ensures you of the following;

• Room temperatures will be adjusted to your personal

settings

• Lower temperatures and lower energy consumption

reduce costs and ensure optimum use of energy

resources.

• The automatic pump motion program protects the

circulation pump against blocking.

Sketch an outline of your heating system

The ECL Comfort controller is designed for a wide range of

heating systems with different configurations and

capacities.

If your heating system differs from the diagrams shown in

section 10, you may want to sketch an outline of the system

about to be installed. This makes it easier to use the

Installer’s Guide, which guides you step-by-step from

installation to the final adjustments before the end-user

takes over.

Note! The controller is pre-programmed with factory

settings that are shown in the relevant sections of this

guide.

Operating the ECL Controller and the ECL Card

The ECL Card has a yellow side for the daily use and a

grey side for the installation and maintenance.

Both sides of the ECL Card are divided into lines

representing the different options of control and

programming.

Select the side of the ECL Card you want to

operate.

The light diode below the inserted ECL Card

indicates the chosen side, ie. left light for daily use

and right light for the installation and maintenance.

(See sections 15 and 16).

Placing the temperature

sensors

Room temperature sensor

(ESM-10, ECA 60 and 61 remote control)

Place the room sensor in the room where the temperature

is to be controlled. Do not place it on outside walls nor

close to radiators, windows or doors.

It is important that the sensors are mounted in the correct

position in your heating system.

Special attention should be paid to the following sensors.

Outdoor temperature sensor

(ESM-10 type)

The outdoor sensor should be mounted on that side of the

building where it is less likely to be exposed to direct

sunshine. It should not be placed close to doors, windows

or air outlets.

Return temperature sensor

(ESMU, ESM-11 or ESMC types)

The return sensor should always be placed in/on a pipe

with return water flow.

Installation

Flow temperature sensor

(ESMU, ESM-11 or ESMC types)

Place the sensor max. 15 cm from the mixing point. In

systems with heat exchanger, Danfoss recommends the

ESMU-type to be inserted into the exchanger flow outlet.

Make sure that the surface of the pipe is clean where the

sensor is mounted.Do not move the sensor after it has

been fastened in order to avoid damage to the sensor ele-

ment.

Adapting the ECL Comfort

controller

While the set-up is in operation, the data transfer-display

will appear.

After initialising, the display will return to the standard dis-

play line C of the yellow side of the ECL Card.

The controller is now ready to control the selected

heating system. You can make your own adjustments/

settings for daily use in the basic set-up and change the

extended service settings.

Installation

Open the lid and switch on the controller. The display

shows the heating system type and the software version.

settings

If several controllers are installed in the heating system you

can write a title on the ECL Card with a permanent ink pen.

Changing from one side of the ECL Card to the other

When changing from the grey side of the ECL Card to the

yellow side, you will always enter line C and the standard

display.

Changing from the yellow side to the grey side, you will al-

ways enter line A - Time and date. See opposite page.

General principles

When the controller is connected and operating you can

check and adjust all or some of the basic settings

referring to the grey side of the ECL Card. Select the grey

side of the ECL Card.

Use the arrow buttons to move from line to line

of the ECL Card, for example line 2:

Use the minus/plus buttons to adjust the

setting(s).

In some displays more than one setting or

value can be adjusted. Use the shift button to

switch between the options. The chosen value

flashes in the range indicator.

When the circulation pump is operating, the activation

direction of the valve is indicated with arrows below the

pump symbol.

If a sensor is not mounted or is disconnected, the display

will indicate it as “

Room temperature influence -

Line 3

This section is only relevant if you have installed a room

sensor. There are two basic principles for control of the

room temperature influence:

A: Max. room temperature limitation

Use this limitation if your heating system is fully equipped

with radiator thermostats and you also want to obtain a

max. limitation of the room temperature. The controller will

allow for free heat gains, i.e. solar radiation or heat from a

fire place, etc.

The max. influence determines how much the

room temperature should influence the flow

temperature.

Go to line 3.

Select the max. influence.

The bar below the range indicator flashes in

the right side of the display.

Adjust the max. influence.
