I-thermostate eyonakele
I-thermostat iyisici esilula sesistimu yokupholisa, kodwa ngenxa yokungasebenzi kahle komsebenzi, idala izinkinga ezinkulu.
Ilimele endaweni evaliwe, empeleni ayikuvumeli ukushayela, futhi endaweni evulekile ngaso sonke isikhathi, kunciphisa kakhulu ukunethezeka kokushayela.
Akunakwenzeka ukungaboni umonakalo ku-thermostat endaweni evaliwe. Uphawu lokuqala ukuthi izinga lokushisa lingena endaweni ebomvu ngokushesha okukhulu. Uma umshayeli ekushaya indiva lokhu, kuzovela amafu entuthu futhi injini izobanjwa.
Ukushisa ngokweqile kungenzeka ngemva kwamakhilomitha ambalwa. Ukuxilonga le nkinga kulula. Uma izinga le-fluid livamile, i-V-belt yepompo yamanzi igxiliwe ngendlela efanele, izinga lokushisa le-radiator aliphezulu kakhulu, futhi inzwa ibonisa izinga lokushisa eliphezulu, bese 
I-thermostat inecala ngalesi simo. Akufanele nakancane ukuthi isivalo serediyetha sikhishwe uma izinga lokushisa lenjini liphezulu, njengoba lokhu kuzodala ukuphuma kungazelelwe koketshezi noma umhwamuko, okungadala ukusha okukhulu.
I-thermostat nayo ingalimala endaweni evulekile. Ukungasebenzi kahle okunjalo akuyingozi kangako enjinini, njengoba kukhona uketshezi olusakazwa kakhulu ngaso sonke isikhathi futhi injini ayikho engozini yokushisa ngokweqile. Kodwa-ke, ukushisa okuncane okuhlala isikhathi eside kunomthelela omubi ekusebenzeni kwenjini. Ehlobo, isici esinjalo cishe singabonakali, futhi ekwindla nasebusika sibonakala ngokucacile. Lokhu kunciphisa kakhulu ukunethezeka kokushayela, njengoba ukushisa kungasebenzi. Injini esebenza ngaso sonke isikhathi emjikelezweni ophezulu, i.e. ngokusetshenziswa ngokugcwele kwe-cooler emazingeni okushisa aphansi, izoshisa ngokuhlelekile. Lokhu kuholela ekwenyukeni okukhulu kokusetshenziswa kukaphethiloli.
Leli phutha futhi kulula kakhulu ukulixilonga. Enye indlela ukuhlola izinga lokushisa. Uma injini ifinyelela izinga lokushisa lokusebenza endaweni yokupaka noma esiminyaminyeni sethrafikhi, futhi ngenkathi ishayela yehla ibe encane, lokhu kubonisa umonakalo ku-thermostat. Ungahlola futhi 
lapho injini ifudumala, izinga lokushisa lamapayipi enjoloba anikeza uketshezi kurediyetha. Uma zombili zisezingeni lokushisa elifanayo, i-thermostat ayinasici.
Yenza izivivinyo ezengeziwe, i.e. khipha i-thermostat bese uhlola emanzini ashisayo uma ivula, akufanelekile. Lokhu kuwukumosha isikhathi nemali.
I-thermostat yamamodeli ajwayelekile ibiza ukusuka ku-PLN 20 kuye ku-50, ngakho-ke uma usola ukuthi ayisebenzi kahle, kufanele ishintshwe. Lapho ushintsha i-thermostat, kufanele futhi unqume ukushintsha isipholile. Lapho uqaqa i-thermostat, olunye uketshezi lusazophuma, ngakho esikhundleni sokungeza phezulu, kungcono ukufaka esikhundleni salo lonke uketshezi kulesi senzakalo. Sizokonga imali ngokwenza lezi zinyathelo ngesikhathi esisodwa.
