i-thermostat ilungelelanisa ngokuzenzekelayo ubungakanani bamanzi angena kwiradiyetha ngokobushushu bamanzi okupholisa kwaye itshintsha uluhlu lokujikeleza kwamanzi ukuhlengahlengisa amandla okutshatyalaliswa kobushushu benkqubo yokupholisa kunye nokuqinisekisa ukuba injini isebenza ngaphakathi kwinqanaba elifanelekileyo lobushushu. I-thermostat kufuneka igcinwe ikwimeko elungileyo yobugcisa, kungenjalo iya kuchaphazela kakhulu ukusebenza okuqhelekileyo kwe-injini. Ukuba ivalve engundoqo ye-thermostat ivulwe kade kakhulu, iya kubangela ukufudumeza kwe-injini; Ukuba ivalve engundoqo ivulwe kwangoko kakhulu, ixesha lokufudumeza kwe-injini liya kwandiswa kwaye nobushushu be-injini buya kuba sezantsi kakhulu.
Lilonke, injongo ye-thermostat kukugcina i-injini ingabandi kakhulu. Ngokomzekelo, emva kokuba injini isebenza kakuhle, i-injini ingabanda kakhulu ngesantya sasebusika ngaphandle kwe-thermostat. Ngeli xesha, i-injini kufuneka imise okwethutyana ukujikeleza kwamanzi ukuqinisekisa ukuba ubushushu be-injini abukho phantsi kakhulu.
