Use of keys: There are three keys on the thermostat panel, key + key-SET key SET
Button +: fast accumulation of values
Button-: Quickly decrease the value
Set key SET: switching of three-layer interface, measured temperature interface, temperature setting interface, parameter setting interface
Press SET briefly, the digital tube flashes and enters the temperature setting interface. At this time, press the + button or the-button to set the temperature. After setting, press SET again to save the data or wait for 5s to save the data automatically.
Press and hold SET to enter the parameter setting interface. P0-P4 are corresponding parameter setting items. In the parameter setting menu, P0-P4 can be switched by pressing the key + or-. When you want to modify a certain parameter, you can switch to a certain item, short press SET to enter, and then press the button to add or subtract.
