Contractor level parameters
The control unit is equipped with a dynamic burner switching
differentialtooptimisetheselectedburnerswitchingdifferential
atvariousboilerloads.Thisfunctioncorrectstheselectedburner
switchingdifferential(parameterHG01)throughload-dependent
burnerruntimes.Theburnerswitchingdifferentialisreducedtoa
minimumvalueof5K,iftheburneroperatingtimeincreasesuptothe
selectedhysteresistime.Thismakestheselectedburnerswitching
differential effective at low boiler loads (rapid heat-up = short
burnerruntime).Thiseffectivelypreventsshortburnerruntimes
andcycling.Withlongerburnerruntimes(highheatdemand),the
switchingdifferentialwillbereducedto5K.Thispreventstheboiler
beingheatedtounnecessarilyhightemperatures.Thisoptimises
theenergyconsumptionoftheheatingsystem.
Thisfunctionpreventsshortburnerruntimesandfrequentcycling.
Thisprotectstheenvironmentandminimiseswear.

Settingrange:1to30min
Individual setting: ______
Ensurethereturntemperatureisraisedinheatingsystemswith
awatercontentgreaterthan20l/kWoutput.Forboilerswitha
pressure-jetoilburneroratmosphericgasburner,theminimum
return temperature is 30 °C, for boilers with pressure-jet gas
burner40°C.

Theoptionalboilersoftstartprotectstheboileragainstcorrosion
thatcanoccurwhen theboiler isheatedfromacoldstate,i.e.
throughcondensateseparationinthedewpointrange.Theboiler
circuitpumpwillbeswitchedOFF,iftheboilerwatertemperature
falls2KbelowthesetvalueTK-min.Thepumpwillbeenabled
whentheboilerwatertemperaturehasexceededtheminimum
limitTK-min.
