1. Temperature a sang a, mahse set requirement a thleng thei lo:
1) Thermostat chu enfiah rawh. Hei hian thermostat-a heating output status, output power ratio setting (thermostat-in he function a neih chuan), temperature compensation setting, over{2}}temperature setting action leh set value, leh PID parameters te a huam a (factory settings en rawh).
2) Heating element leh heating control circuit te chu a thawk tha em tih enfiah thin ang che. Oven thenkhatah chuan heating element tam tak an hmang a; Group tinte an thawk tha em tih enfiah rawh. Hei hi clamp meter hmanga heating element tin phase tina current teh emaw, heating elements te inzawm loh leh an resistance tehna hmanga tih theih a ni.
2. Temperature a sang lo, a lum lo:
1) Thermostat status indicator leh settings te enfiah thin ang che.
2) Heating elements leh control circuit te enfiah la, AC contactor chu a engage dik em tih te, heating circuit breaker a inhawng em tih te, intermediate relay a thawk tha em tih te.
