Set startup temperature: Press the "up" button once to display the starting temperature. Long press the "up" button for about 3 seconds,The required temperature can be set by the up and down keys Set the stop temperature: Press the button once to display the stop temperature. Long press the button for about 3 seconds and the stop temperature number flashes. The required temperature can be set by the up and down keys Press "Up 1" Button & "Up 2"Button at the same time to setting mode 1.Automatic conversion of refrigeration and heating mode 2.Control mode of return difference;Temperature display resolution 0.1 3.The temperature controller has the characteristic of high accuracy, high sensitivity, high stability. 4.Support temperature correction and support for power loss (the parameters of the sudden power failure are still valid 5.Application range is like home temperature control, farm, various cold storage, greenhouse, aquarium, etc Display Type:Digital Style:Standing Station Temperature sensor: NTC 10K Senor length:1.0m Temperature measuring range: -55 C ~ 120 C Resolution: 0.1 C Accuracy:1 C Power supply: 110-220VAC 50/60Hz, 12V DC , 24V DC(Please choose power supply when ordering) Power consumption: P0 : Delay start 0-60 minutes P1 : Delay start 0-60 minutes P2 High temperature alarm P3~120C 120C P3 Low temperature alarm P2~-55C -55C How to restore factory Settings press the "Down 1" and "Down 2" button at the same time, the factory setting is restored Temperature correction Press "Up 1 "and "Down 1 "at the same times for 3 second. positive value = measured value + corrected value(group 2 temperature correction is the same method ) Heating Mode--Start temperatureStop temperature You can set 1 heating 1 cooling or 2 cooliong or 2 heating.
