Arelaychinhu chemagetsi chinoshandisa misimboti yemagetsi kana zvimwe zvinokanganisa muviri kuti zviite "otomatiki on/off" yemasekete. Basa rayo guru nderekudzora on-off yemasekete makuru emagetsi/akakwira nemagetsi madiki/masaini, ukuwo zvichiita kuti magetsi aparadzane pakati pemasekete kuti ave nechokwadi chekuti mugumo wekudzora wakachengeteka.

Mabasa ayo makuru anogona kupatsanurwa muzvikamu zvitatu:

1. Kudzora uye Kuwedzera: Inogona kushandura masaini ekudzora asina simba (akadai semagetsi emumiampere-level anoburitswa nema microcomputer nemasensa e-single-chip) kuita masaini akasimba anokwana kufambisa zvishandiso zvine simba guru (senge mota nemaheater), zvichishanda se "signal amplifier". Semuenzaniso, mudzimba dzakangwara, masaini madiki emagetsi anotumirwa nemaapplication efoni anogona kudzorwa kuburikidza nemarelay kuti abatidze uye adzime simba rema air conditioner nemarambi epamba.

2. Kupatsanurwa kwemagetsi: Hapana kubatana kwemagetsi kwakananga pakati pedunhu rekudzora (voltage yakaderera, small current) nedunhu rinodzorwa (high voltage, large current). Mirayiridzo yekudzora inongotumirwa chete kuburikidza nemasaini emagetsi kana emaziso kudzivirira high voltage kuti isapinde mu control terminal uye kukuvadza michina kana kuisa njodzi kuchengetedzeka kwevashandi. Izvi zvinowanzo kuwanikwa mumadunhu ekudzora ezvishandiso zvemaindasitiri nemidziyo yemagetsi.

3. Kurongeka uye Dziviriro: Inogona kubatanidzwa kuti iite logic yakaoma yedunhu, senge kuvharirana (kudzivirira mamota maviri kuti asatange panguva imwe chete) uye kunonoka kudzora (kunonoka kubatana kwemutoro kwenguva yakati mushure mekubatidzwa). Mamwe marelay akatsaurirwa (akadai serelay dzinopfuura mwero uye relay dzinopisa zvakanyanya) anogonawo kutarisa kusarongeka kwedunhu. Kana magetsi ari makuru zvakanyanya kana tembiricha yakakwira zvakanyanya, anozodzima dunhu otomatiki kudzivirira michina yemagetsi kubva mukukuvadzwa zvakanyanya.
