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 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.

However, you might come across some settings that

are not listed in this instruction. These settings are used in

connection with optional modules, and you can find a

description of the settings and the corresponding

parameters in the instruction for optional module in

question.

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:

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 di-

rect sunshine. It should not be placed close to doors or

windows.

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.

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.

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.

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.

ROOM

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.

Line

indicator

Set the proportional band.

A higher value will result in a stable, but slow

regulation of the flow temperature.

Go to line 5.

Set a high integration time constant to obtain a

slow but stable reaction to deviations.

A low integration time constant will make the

controller react fast but with less stability.

Go to line 6.

Set the running time of the motorized valve

according to the example on the opposite page.

This is the time it takes the valve to move from

closed to fully open position.

Go to line 7.

Set the neutral zone to a high value if you can

accept a high variation in flow temperature.

When the actual flow temperature is within the

neutral zone, the controller does not activate the

motorized valve.

Note! The valve is symmetrically around the

flow reference value.

If you want to tune the PI-regulation precisely, you can

use the following method:

• Set the integration time (line 5) to its max. value (999 sec.).

• Decrease the value for the proportional band (Line 4) until

the system starts hunting with a constant amplitude (it might

be necessary to force the system by setting an extreme

value).

• Find the critical time period on the temperature recording or

use a stop watch.

This time period will be characteristic for the system, and you

can evaluate the settings from this critical period.

Integration time = 0.85 x critical time period

Proportional band = 2.2 x proportional band value in the

critical time period.

If the regulation seems to be too slow, you can decrease the

proportional band value by 10%.

Note! Make sure there is a consumption when you set the

parameters.

How to calculate the running time of the motorized valve

The running time of the motorized valve is calculated using the

following methods:

Seated Valves

Running time = Valve stroke (mm) x actuator speed (sec./mm)

Example: 5.0 mm x 15 sec/mm = 75 sec.

Rotating Valves

Running time = Turning degrees x actuator speed (sec./degr.)

Example: 90 degrees x 2 = 180 sec.

The setting of reduced temperature depends on

the outdoor temperature, when the outdoor

temperature is above the set limit.

The lower the outdoor temperature the less the

temperature reduction. When the outdoor

temperature is below the set limit, there is no

temperature reduction.

OFF: The reduced temperature setting will be

constant at all outdoor temperatures.

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.

Service parameters 12-13

In order to avoid load peaks in the supply network, the

flow temperature reference can be set to increase slowly

after a period with reduced temperature. This causes the

valve to open slowly.

In order to shorten the heating-up period after a reduced

temperature period, the flow temperature can be

increased temporarily.

If a room sensor is installed, the boost stops when the

optimising period is over or the room temperature has

been reached.
