Review on LM YN Thermostat Temperature Controller Test, Measure & Inspect by Adam Ross

This temperature module works fine but there are a few things to note: 1. The input says 24V. I don't see any documentation on amps, I have the 20V 4.3A power supply is not turned on. It seems to have worked with a regulated 12V 20A power supply, but I haven't tested the output. Now I have a 24V, 15A power supply, it works fine.3. You can take it up to 210°C, which is better than most 12V digital thermostats that only work up to 110°C.2. The documentation sucks, but this is a very simplified controller. The downside is that you don't have much control. Steps to use: A. Connect it - see attached pictures (different controller but same wiring) B. Connect it to C. Press and hold the left button for a few seconds until two temperatures are visible. Now press once briefly, the upper temperature flashes. Use the two right buttons to set the desired low temperature. Quickly press the left button again, the bottom temperature will flash. Set the desired high temperature. When the upper temperature is lower than the lower temperature, it is heating mode. Otherwise it is in cooling mode. Press and hold the left button again for a few seconds and it will display the temperature and either H or C for heating and cooling. D. If there is ---- next to numbers on the screen, the temperature sensor is not connected or not working. That's it, there are no other options. Although it works fine. Enjoy.
