12V DC Thermostat Controller All-Purpose Digital Temperature Controller Thermostat with Sensor Digital Display Microcomputer

The unit works great for my peltier running at 12v 6amp, the beep when pressing the button is a little annoying but works just great, being able to adjust the unit takes a little figuring out as instructions are a translation from probably Chinese. I would advise getting a hobby box to fit the unit for projects but I am super happy with it

Already set to centigrade.Remember to calibrate, as mine was abt 5 centigrade off

Far better than expected.

Works amazing

The media could not be loaded. Ok wired up a per diagram, raise the blue digits above ambient nothing happens. Drop the blue digits below ambient unit kicks in heating my printer. Seems to be in reverse, checked wiring Asperger’s diagram. Very unsure as to reverse cabling. Any ideas. Gave 1 star till solution found, if running a cooler this would work. However this was purchased as heater controller for resin printer.

This product didn’t work it arrived faulty

Switching a 12v 16A load (it's rated for 12v 20A), it seemed to work fine. After 6 hours running, the relay gave up the ghost and failed open (mercifully not failing closed). Temperature regulation still seems to work, but no switched output.

it start when is reaching below the setup temperature but not switches off after, could by my one faulty.
