Save energy - save money - improve your comforttemperatureThe ECL Comfort controller is designed by Danfoss fortemperature 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 energyresources.

• The automatic pump motion program protects thecirculation pump against blocking.

Sketch an outline of your heating systemThe ECL Comfort controller is designed for a wide range ofheating systems with different configurations andcapacities.If your heating system differs from the diagrams shown insection 10, you may want to sketch an outline of thesystem about to be installed. This makes it easier to use theInstaller’s Guide, which will guide you step-by-step frominstallation to final adjustments before the end-user takesover.

Note! The controller is pre-programmed with factorysettings which are shown in the relevant sections of thisguide.

However, you might come across some settings thatare not listed in this instruction. These settings are used inconnection with optional modules, and you can find adescription of the settings and the correspondingparameters in the instruction for optional module inquestion.

11aFor easy access, you should mount the ECL Comfortcontroller near the heating unit. Select one of the threefollowing methods:• Mounting on a wall• Mounting on a DIN rail• Mounting in a panel

Screws and rawlplugs are not supplied.

Mounting on a wallSocket 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 thecontroller in the box. Secure the controller with the fixingscrew.

Mounting on a DIN railMounting kit: Order code No. 087B1145.A mounting kit is necessary to mount the box with thecontroller on a DIN rail.

Mounting in a panelConnector set: Order code No. 087B1148.The panel plate thickness must not exceed 3 mm.Prepare a cut-out with the dimensions 92 x 138 mm. Pull offthe right side of the lid by means of a screwdriver.Insert the controller into the panel cut-out and fix it with thetwo locks which are placed diagonally in two corners of thecontroller.

14Placing the temperaturesensorsIt is important that the sensors are mounted in thecorrect 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 sideof the building where it is less likely to be exposed to di-rect sunshine. It should not be placed close to doors orwindows.

Flow temperature sensor(ESMU, ESM-11 or ESMC types)Place the sensor max. 15 cm from the mixing point. Insystems with heat exchanger, Danfoss recommends theESMU-type to be inserted into the exchanger flow outlet.

Make sure that the surface of the pipe is clean at the areawhere the sensor is mounted.Do not move the sensor after it has been fastened inorder 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 cmfrom the mixing point. It should always be placed on a pipein 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 temperatureis to be controlled. Do not place it on outside walls or closeto radiators, windows or doors.

Understanding the ECL CardThe ECL Card contains factory settings for a standardheating system. If the actual heating system differs fromthe standard system, the controller must be adjustedaccordingly. After the adjustment, the new settings shouldbe stored on the ECL Card.

For ECL Card copying and daily use includingadjustment of temperatures and time periods, insert theECL Card with the yellow side facing you.

For system set-up adjustments, the grey side of the ECLCard - the installer’s side - must be facing you.

As a main rule, the ECL Card should always remain inthe 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 systemyou can write a title on the ECL Card with a permanentink pen.

How to insert your ECL Card the first timeAfter the power has been switched on, open the lid on thefront side of the controller.

Place the ECL Card with the yellow side facing you. Thisenables the controller to read the ECL Card data.The controller immediately starts to copy the factorysettings and heating system type from the ECL Card. Aftercopying, the display will show the heating system type thecontroller is set to control. After approx. 10 sec. the displaywill change to display line C.

The controller is now ready to be set to control yourheating system.

This section is only relevant if you have installed a roomsensor. There are two basic principles for control of theroom temperature influence:

A: Max. room temperature limitationUse this limitation if your heating system is fully equippedwith radiator thermostats and you also want to obtain amax. limitation of the room temperature. The controller willallow for free heat gains, i.e. solar radiation or heat from afire place, etc.

The max. influence determines how much theroom temperature should influence the flowtemperature.

Set the proportional band.A higher value will result in a stable, but slowregulation of the flow temperature.

Go to line 5.

Set a high integration time constant to obtain aslow but stable reaction to deviations.A low integration time constant will make thecontroller react fast but with less stability.

Go to line 6.

Set the running time of the motorized valveaccording to the example on the opposite page.This is the time it takes the valve to move fromclosed to fully open position.

Go to line 7.

Set the neutral zone to a high value if you canaccept a high variation in flow temperature.When the actual flow temperature is within theneutral zone, the controller does not activate themotorized valve.

Note! The valve is symmetrically around theflow reference value.

If you want to tune the PI-regulation precisely, you canuse 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 mightbe necessary to force the system by setting an extremevalue).

• Find the critical time period on the temperature recording oruse a stop watch.

This time period will be characteristic for the system, and youcan evaluate the settings from this critical period.

Integration time = 0.85 x critical time periodProportional band = 2.2 x proportional band value in the

critical time period.

If the regulation seems to be too slow, you can decrease theproportional band value by 10%.

Note! Make sure there is a consumption when you set theparameters.

How to calculate the running time of the motorized valve

The running time of the motorized valve is calculated using thefollowing methods:

Seated ValvesRunning time = Valve stroke (mm) x actuator speed (sec./mm)Example: 5.0 mm x 15 sec/mm = 75 sec.

Rotating ValvesRunning time = Turning degrees x actuator speed (sec./degr.)Example: 90 degrees x 2 = 180 sec.

Adapting the ECL Comfort controller to the heatingsystem

29bCheck list

If your heating system differs from the diagram shown onthe overleaf of the cover, you should check and perhapsalter the following service parameter.

To ensure that you have the correct settings see section10 for examples of different heating systems.

✓ Turn the ECL Card so that the grey side facesyou.

Set the time and the date (Line A)See section 17.

Check all settings on the grey side of theECL CardSee sections 20 to 26.

Check all settings in the extended serviceparameters line 10 to 199.

29a Check list

✓ Is the ECL Comfort controller ready for use?

Make sure that the power supply is connected toterminals 1 (Live) and 2 (Neutral).See section 12 or 13.

Check that valves and pumps are connected tothe correct terminals.See section 12 or 13.

Check that all sensors are connected to thecorrect terminals.

Mount the controller, and switch on the power.

Insert the ECL Card with the yellow side facing

you and push , if necessary.

See section 15.

Select manual operation in the controller mode.See section 2 in the user’s guide.

Check that valves open and close, and thatpumps start and stop when operated manually.See section 19.

Check that the temperatures shown in display Aand B match the actual sensors, both for circuitI and circuit II.See section 1 in the user’s guide.
