

ONSENhotwaterheatersfeatures



 Easytooperate–theoperationsareintelligent,automatic‐controlwiththeadvancedmicrocomputerchips

controllingproportionalvalve,infinitespeed,exhaustfanspeed,andheavyloadcombustiondevice. 

 Rainproofoutdoorinstallation–thewaterheateritselfisinstalled outdoors, with special hermitical

rainproofstructures.Airforcombustionisextractedfromtheatmosphereandtheexhaustemittedbackto

atmosphere. 

 Multiple remote controls (optional) – the hot water heater is capableoftakingupto3remotecontrols

installedatdifferent roomsat the same time. Controlling prioritycanbeswitchedamongalltheremote

controls.

 Non‐polardoublefrequencysignalcarrierremotecontrol(optional)–theadvancedmethodofsignalcarrier

&communicationisusedbetweenthe remotecontrol and waterheatercontrol board.Theinstallationis

easyandconvenientbyusingnon‐polarandlowvoltagewires.

 Automaticerrordetection–whenthehotwaterheaterisinoperation,thecontrolboardwillmonitorthe

workingstateofcontrolcircuits,safetyunits,fan,proportional valve etc. if there is problem, the water

heaterwillstopworking,andanerrorcodewillbedisplayedontheremotecontroliffitted.

 Intelligentoxygen‐supply,safetyprotection–toensureacomplete&highlyefficientcombustionprocessis

maintained,themicrocomputerwillautomaticallydetectiftheoxygencontentandairflowissufficient.Fan

speedwillberaisedautomaticallytoavoidincompletecombustionwhenthereisablockagetoguarantee

smoothventilation.Whenthefanspeedreachesacertainpoint(CO boundary), the intelligent Oxygen

supplysafetyprotectionistriggeredandflameisautomaticallyextinguished.

 Microcomputersmartcontrol–themicrocomputerinthewaterheaterwillworkouttheperfectworking

parameters to ensure constant hot water temperature delivery based on input data such as inlet water

temperature,presettemperatureetc.

 Digitalcontroltemperature–realtimetemperatureismonitoredbyasensorprobeandprovidesfeedback

tomicrocomputer.Anautomaticadjustmentofgasandairsupplyismaintainedaccordingtofeedbackdata

toensureaconstanttemperatureofthewaterdelivery.

 Highenergyefficiency–thewaterheatermicrocomputernotonlypreciselycontrolstheamountofsupply

gasthroughgasregulator,italsoadjuststheamountofairneededforcompletecombustion.ONSENwater

heatershavetwobuilt‐infunctions(intensifiedcombustionandforcedheattransfer)thatallowthewater

heaterratedefficiencytobehigherthannationalstandardrequirements. 
