5.2 OPERATION
Thepumpcanoperatein5differentmodes.Wecansetthepumpinthemostappropriatemode,dependingonthe
systemwherethepumpoperates.
Thepumpmodes:
 Automaticmode(factorydefault),
 Proportionalpressure,
 Constantpressure,
 Constantspeed,
 Combinedmode(allmodeindicatorsareoff)–onlyavailableonNMT(D)MAXC.

Automatic mode
Inautomaticmodethepumpautomaticallysetstheoperatingpressure,dependingonthehydraulicsystem.
Bydoingso,thepumpfindstheoptimaloperatingposition.
Thismodeisrecommendedinmostsystems.
Theparameterscannotbeset;theycanonlybescrolledthrough.

Proportional pressure
Thepumpmaintainsthepressurewithrelationtothecurrentflow.The
pressureisequaltothesetpressure(Hsetonthedrawing)atmaximumpower;at
0flowitisequaltoHQ%(default50%,HQ%canbesetonthepumpwebpage)of
thesetpressure.Inbetween,thepressurechangeslinearly,relativetotheflow.
Inregulatedmodewecanonlysetthepumppressure(Hsetonthedrawing).We
canonlyscrollthroughtheotherparameters.


Constant pressure
Thepumpmaintainsthecurrentlysetpressure(Hsetonthedrawing),from0flow
tomaximumpower,wherethepressurebeginstodrop.
Atconstantpressure,wecanonlysetthepressure(Hsetonthedrawing)whichthepump
willmaintain.Wecanonlyscrollthroughtheotherparameters.

Constant speed
Thepumpoperateswiththecurrentlysetspeed(RPMsetonthedrawing).
Intheunregulatedmode,wecanonlysetthespeedatwhichthepumpwilloperate.We
canonlyscrollthroughtheotherparameters.

Combined mode
Multiplelimitscanbesetonlyoverthewebinterface.Noneoftheothermodesareon.
Night mode
Whenthepumpisoperatinginnightmode,itautomaticlyswitchesbetweenthecurrentmodeandnight
mode.Switchoccursbasedonthetemperatureofthemedium.
Whileinnightmodeitsiconisturnedonandthepumpoperatesinchosenmode.Ifthepumpsensesdropin
temperatureofthemediumfor15‐20°C(intimeframeof2hours),iconstartstoblinkandthepumpswitchesto
nightmode.Whenthetemperatureofthemediumrises,blinkingstopsandthepumpgoesbacktopreviously
chosenoperationmode.
Nightmodecanonlyworkincomplimenttoothermodesandisnotamodethatcanrunbyitself.
