[Instructions]

Key description: The SET key is the setting key and also the plus key; the C/F key is the Fahrenheit and Celsius conversion key.

When the actual temperature is displayed, press the SET button, the setting number below flashes (the setting temperature below flashes), and then SET (+) C/F (-) to set the desired set temperature, and the light will be displayed after the setting is completed It will automatically confirm and return in 3 seconds. At this time, the controller will automatically switch on and off the relay according to the set temperature. The rated output of the thermostat is a 12V20A relay, which can meet various high-power requirements. Please ensure that the wiring is correct.

Under normal working environment, short press C/F (-) key to switch between Fahrenheit and Celsius.

Under normal working environment, long press the SET button for 5S to enter the main menu setting, press SET (+), C/F (-), then you can select P1-P8 mode, after confirming the mode, press and hold SET (+) at the same time ,C/F(-) enter this mode to set parameters. At this time, the right number below flashes, and then adjust the size of the parameter through the SET (+) and C/F (-) keys, and it will automatically save and exit after 3S. The setup is complete.
