Instructions for user
Connect the power supply and equipment, the measuring temperature is displayed, press the "SET" button, press " + or - " to set the desired temperature (long press " + or - " to quickly increase or decrease), press "SET" to confirm the setting and return, controller
automatically performs the relay ON/OFF.the thermostat output is 10A relay, meet a variety of high-power loads,
LED Indicator: LED off indicates the relay off; Lighting,indicates the relay is closed.
Digital LED Tubes: "LL" indicates sensor open, "HH" indicates overrange, the relay will be forcibly disconnected; "---" indicates high temperature alarm
Long press the "SET" button to enter the main menu settings, press " + or - " to switching between P0-P6,then long press "SET" or 10 seconds without keystrokes to confirm the setting and return.

Buttons:
