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 and hot water temperatures will be adjusted to

yourpersonal 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 will guide you step-by-step from

installation to final adjustments before the end-user takes

over.

Note! The controller is pre-programmed with factory

settings which are shown in the relevant sections of this

guide.

• 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.

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 at the area

where the sensor is mounted.

Do not move the sensor after it has been fastened in

order to avoid damage to the sensor element.

Placing the temperature

sensors

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:

Return temperature sensor

(ESMU, ESM-11 or ESMC types)

The return sensor should always be placed max. 15 cm

from the mixing point. It should always be placed on a

pipe in which the water flow never stops.

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 or close

to radiators, windows or doors.

Outdoor temperature sensor

(ESM-10 type)

The outdoor sensor should be mounted on the north side of

the building where it is less likely to be exposed to direct

sunshine. It should not be placed close to doors or

windows.

Inserting the ECL Card

How to insert your ECL Card the first time

After the power has been switched on, open the lid on the

front side of the controller.

Place the ECL Card with the yellow side facing you. This

enables the controller to read the ECL Card data.

The controller immediately starts to copy the factory

settings and heating system type from the ECL Card. After

copying, the display will show the heating system type the

controller is set to control. After approx. 10 sec. the display

will change to display line C.

The controller is now ready to be set to control your

heating system.

Installation

Understanding the ECL Card

The ECL Card contains factory settings for a standard

heating system. If the actual heating system differs from

the standard system, the controller must be adjusted

accordingly. After the adjustment, the new settings should

be stored on the ECL Card.

For ECL Card copying and daily use including

adjustment of temperatures and time periods, insert the

ECL Card with the yellow side facing you.

For system set-up adjustments, the grey side of the ECL

Card - the installer’s side - must be facing you.

As a main rule, the ECL Card should always remain in

the controller during service, maintenance and settings.

If the card is removed please note that:

• The controller settings are locked after approx. 10 min.

• The ECL Card must not be exposed to direct heat or

sunshine

If several controllers are installed in the heating system

you can write a title on the ECL Card with a permanent

ink pen.

Installation

Adjusting the ECL Card

settings

Update of the ECL Card after maintenance and

service

All new settings can be stored on the ECL Card. For

details about copying, see section 34. Insert the ECL

Card with the yellow side facing you.

When the copying is finished display line C will appear

You can make other changes in the day plan, set

time and date or change settings

(see User’s Guide).

General principles

When the controller is connected and operating you

can check and adjust all or some of the basic settings

on 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

settings.

In some displays more than one setting or

value can be adjusted. Use the shift button to

switch between the possibilities.

The circuit selector shifts between circuit I

and II. You can adjust all settings and service

parameters individually in both circuits, ie.

circuit II.

Go to line 9 (bottom line)

Accept to copy as indicated. No other keys are

active.

Basic set-up

Setting the time and date -

Line A

In case of a power failure which lasts longer than 12 hours,

the time and the date have to be set again.

All other settings are stored as programmed.

Basic set-up

Monitoring temperatures and

system units - Line B

Go to line B.

The activity of the motorized valve is shown as arrows

below the valve symbol. When the circulation pump is

operating, it is indicated as ON below the pump symbol.

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

will indicate it as “

- -”.

If the sensor is short-circuited, the display will indicate it as

“

- - - “.

If you are in doubt, remove the controller and check the

ohmic value between the relevant terminals.
