- For 10 minute the variance of temperature(Y) is less than 2
℃
"E5"message is displayed on the panel.
③
The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 11 minutes (Y=A2-A1)
- For 1 minute the variance of temperature(Y) increases more than 7
℃
(0.3V) "E6"message is displayed on the
