1. Temperature internal parameters setting
Press the "temperature" key for about 3 seconds, the temperature display area displays the
password prompt "Lc", and the speed display area displays the password value.
By adding keys, reducing keys and shift keys, modify to the required password value. Then
click the "temperature" key, if the password value is not correct, the controller automatically
returns to the normal display state; if the password value is correct, then enter the temperature
internal parameters setting state, and then click "temperature" key to modify each parameter
in turn. After modification, press the "temperature" button for 3 seconds and exit the internal
parameter setting state, and the parameter value is automatically saved.
