Save energy - save money - improve your comfort

temperature

The ECL Comfort controller series is designed by Danfoss for

temperature control of heating, hot-water, ventilation and

cooling systems.

The ECL Comfort controller ensures you of the following;

•

Room, hot-water, ventilation or cooling temperatures will

be adjusted to your personal settings.

•

Lower temperatures and lower energy consumption

reduce costs and ensure optimum use of energy resources.

Sketch your application

The ECL Comfort controller series is designed for a wide

range of heating, hot-water, 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).

Basic principles of the L32 application

Typical use:

Typically the  ow temperature is always adjusted according to

comfort requirements. The colder it gets outdoor, the higher

the  ow temperature of the  oor circuit will be. When heating

is required, the heat generator (which typically is the boiler) is

activated.

When the outdoor temperature increases and heating operation

no longer is required, the controller can switch to cooling.

Chilled water is then circulated in the system to keep the room

temperature on the comfort level. When cooling is required,

the cooling generator (a water chiller) is activated. The  ow

temperature is controlled with due consideration to the air

humidity. The controller avoids condensation on the  oor.

Humidity and room temperature are measured by the remote

control ECA 63.

Program for the drying of  oor pavement:

A special program for the drying of newly made concrete  oor

pavement can be activated. For 3 days the  oor temperature will

typically be held at 25

o

C and for the next 4 days typically at

50

o

C. In section 32 you can read more about activation, advice

and settings.

Installation

It is important that the sensors are mounted in the correct

position in your system.

The temperature sensor mentioned below are sensors used

for the ECL Comfort 200 and 300 series which not all will be

needed for your application!

Outdoor temperature sensor (ESMT)

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.

Flow temperature sensor (ESMU, ESM-11 or ESMC)

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

systems with heat exchanger, Danfoss recommends that the

ESMU-type to be inserted into the exchanger  ow outlet.

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

sensor is mounted.

Return temperature sensor (ESMU, ESM-11 or ESMC)

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

return water  ow.

Room temperature sensor (ESM-10, ECA 60 / ECA 62

room panel or ECA 61 / ECA 63 remote control)

Place the room temperature 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.

Hot-water temperature sensor (ESMU or ESMB)

Place the hot water sensor according to the

manufacturer’s speci cation.

Boiler temperature sensor (ESMU, ESM-11 or ESMC)

Place the sensor according to the boiler manufacturer’s

speci cation.

Flow / air duct temperature sensor (ESM-11, ESMB,

ESMC or ESMU types)

Place the sensor close to the exchanger.

Surface temperature sensor (ESMB-12)

Place the sensor in the surface of the  oor.

Valid for ESM-11: Do not move the sensor after it has been

fastened in order to avoid damage to the sensor element.

How to insert your ECL Card the  rst 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 system type and

factory settings from the ECL Card. After copying, the display

will show the system type the controller is set to control. After

approx. 10 sec. the display will change to display line C.

Understanding the ECL Card

The ECL Card contains factory settings for a standard

system. If the actual system di ers 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 cannot be changed after approx.

25 min.

•

The ECL Card must not be exposed to direct heat or

sunshine

If several controllers are installed in the system you can

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

Do not remove the ECL Card while copying!

When you store your personal settings on your ECL Card, your

factory settings will be overridden.

How to determine another heat curve, if necessary:

Choose the calculated  ow temperature for your system and

the determined min. outdoor temperature for your area.

Pick the heat curve closest to the crossing point of these two

values.

The setting of the desired room temperature has an in uence

on the calculated  ow temperature (heat curve), no matter if a

room temperature sensor is connected or not.

Floor heating systems
