It is very good temperature switch controller. It works perfectly. I ordered the item for 110-220vac power In order to program the bandwidth working temperature you have to do the following steps : 1) put power: 110-220VAC —-> red and black cables 2) The controller XY-W3001 shows the sensor temperature 3) Press the button UP arrow for 5 seconds until the led flashes 4). Press the UP or DOWN arrows to put the level of the lowest temperature Then 5) Press the button DOWN arrow for 5 seconds until the led flashes 6) Press the UP or DOWN arrows to put the level of the Highest working temperature
