Safety instructions
1. PleasereadandfollowtheInstallationandOperatingInstructionscarefully,toensurethelonglifeandreliableoperation
ofthisappliance
2. Theboilerinstallationandallelectricalconnectionsmustbemadebyanqualifiedperson.
3. Manufacturermaymakeminorchanges,ifnecessaryintheappliancethatwillnotbeshownintheoperatinginstruc-
tions,solongasthemainfeaturesoftheboilerremainthesame.
4. TheControlPanelispre-setbythemanufacturersoitisreadytobeoperated,howeveryoucanadjustthemanufacturer
settingstoyourindividualrequirements.Appropriateprogrammingensurescomfortableandeconomicaloperationof
theboiler.
5. Itisnecessarytocutoffallpowersupplyusingeithertheboilerswitchesorswitchingoffthefusepriortoremovingthe
boilerfrontcasing.
6. Donotdrainthewaterfromcentralheatingsystemaftertheheatingseason.
7. Inbuildingsweretheboilerisoperatedonlyontemporarybasisandtheheatinginstallationcanbeexposedtofrost,
theboilermustbeoperatedatalltimesusinganti-freezemode,ortheheatinginstallationmustbeprotectedusingan

Basic information about the boiler
Theprovidedinstallationandoperatinginstructionsreferstothefollowingboilertypes:
• EKCO.M1z,EKCO.M1Nz,EKCO.TM–wall-mountedelectricboiler,single-functional,withtheweathercompensation,
enabletoco-operatewithoneortwocentralheatingcircuits(e.g.radiatorsandunder-floor),withtheDHWcylinder
andthecentralheatingflowpump.
Theboilersmentionedaboveshallbeoperatedonaclosed(unvented)centralheatinginstallationwithaforced
watercirculation,protectedinaccordancewiththebindingnormsandstandards.Theboilerscanalsoworkon
opened(vented)centralheatinginstallationswithforcedcirculationprotectedinaccordancewiththebindingnorms
andstandards.
Theyareequippedwithafrontcontrolpanel,whichtakesintoconsiderationcurrentoutdoortemperature.This
featureensuresanalmostautomaticoperationoftheboiler.Accuratesettingoftheheatingparametersensures
economicaloperationoftheboiler.
Theboilerisequippedwithacirculatingpump,amanometerandanautomaticventvalve.
Theboilerisalsoequippedwithanumberofothersafetydevices:
• flowcontrolsystem,
• innertemperaturesensor,
• temperaturecut-outandsafetyvalve.
Thepoweroftheboilershouldbeadjustedaccordingtotheheatlossoftheheatedbuilding.

Installation work
1. Hangtheboilerupinaverticalpositiononfixingscrews
with inlet and outlet pipes to the bottom, maintaining
clearancesfromthewallsandtheceiling(seefig.1).
2. Connecttheboilertoacentralheatingsystemequipped
withcut-offvalves(seefig.2&fig.3).
3. Fillthecentralheatingsystemwithatreatedwater,that

Thecontrolpanelallowsforitsco-operationindifferent
centralheatingsystems,howeverthecontrolpanelneeds
tobesetaccurately(see„FrontcontrolPanel”„Extanded

Special start-up procedure for EKCO.TM
Aflowratereadingerrormayoccurifyoustart-upthe
unit at low ambient temperature. This error may occur
becausethephysicalpropertiesofantifreezesolution.
Underthiscircumstances,thespecialstart-upprocedure
willstartifyou:
- activatethecentralheatingorcylinderheatingmodeusing
thecontrolpaneldisplay(seefig.14),
- closetheNAentryonZIOboard(seefig.6),
- noticethe„!”(anexclamationmark)atmainviewpanel
display(see„Failures”page12).
Asaresult,themediumwillbewarmeduptotempera-
turethatenabledyoutoreadtheflowratecorrectly.The
duration of procedure depends on both the installation
capacityandthetemperatureinsidethesystem.
Whenthemainviewpaneldisplay(fig.10,11)andthe
central heating parameters view (fig. 31) shows boiler
powervalue and („-”, „--”)alter-nately it means thatthe
procedureisstarted.
The procedure will switch off automatically and the
unit will start normal operation once the minimal flow
rateisreached.

Electric installation should be equipped with residual
current protective devices and other solutions which
will ensure disconnecting the unit from the source of
power (intervals between all their poles should not be
less than 3 mm).
Note: 4, 6 and 8kW boilers are factory pre-set to work as single phase boilers [figure 5b]. If you
intend to connect the boiler to a three-phase system, take off the [15] wire set.
