Instructions for use:

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:

• P0 : Cooling / Heating; Range: C/H; Default: C
• P1 : Hysteresis Setting; Range:0.1-15; Default: 2
• P2 : Highest Setting Limit; Range:110; Default: 110
• P3 : Lowest setting Limit; Range:-50; Default: -50
• P4 : Temperature Correction; Range:-7-7°C, Default: 0°C
• P5 : Delay Start Time; Range:0-10 Minute; Default: 0
• P6 : Key Tone Switch; Range:0-110; Default: Off
• When the Thermostat is power off, long press " - or + ", you can restore the factory settings
