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 and hot water 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 will guide 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 which are shown in the relevant sections of this

guide.

Identifying the system type

In this section you find the most frequently used systems. If

your system is not quite as shown below, find the diagram

two locks which are placed diagonally in two corners of the

controller.

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 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.

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:

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.

Boiler sensor

(ESMU, ESM-11 or ESMC types)

Place the sensor according to the boiler manufacturer’s

specification.

Do not move the sensor after it has been fastened in

order to avoid damage to the sensor element.

Return temperature sensor

(ESMU, ESM-11 or ESMC types)

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

with return water flow.

Hot water temperature sensor

(ESMU or ESMB types)

Place the hot water sensor according to the

manufacturer’s specification.

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.

Installation

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 the heating system type from the ECL Card. After

copying, the display will show the heating system type the

controller is set up to control. After approx. 10 sec. the dis-

play will change to display line C.

The controller is now ready to be set to control your

heating system.

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

Setting the time and date -

In case of a power failure which lasts longer than 12

hours, the time and date have to be set again.

This section is only relevant if you have installed a room

The max. influence determines how much the

room temperature should influence the flow

temperature.

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 setting of reduced temperature depends

on the outdoor temperature, when the outdoor

temperature is higher than the set limit.

The lower the outdoor temperature the less

the temperature reduction. When the outdoor

temperature is lower than the set limit, there is

no temperature reduction.

Adjusting the service

parameters

In addition to the settings in line 1 to 7 on the grey side

of the ECL card, there is an extended service menu

from line 10 and onwards.

When you have entered all your personal settings, turn

the ECL Card over so that the yellow side faces you.

If you want to copy the new settings to the ECL Card

(recommended by Danfoss), see section 34 “Copying

data with the ECL Card”.

Make a note of your new settings on the parameter list

in section 31.

Push repeatedly to reach the lines

numbered 10 and onwards.

Now you can move to any line of your choice.

Set the parameter value.

You can select any of the two circuits no

matter what line you are in. You will not

necessarily enter the same line number.

See the service parameters in section 31.
