Review on MYPIN Universal Digital Temperature Controller TA6-SNR with Dual Display, SSR-25DA Relay, and K Type Thermocouple - Accurate to 0.2%, 7 Output Combinations - Ideal for F/C Conversion by Larry Simpson

Purchased to control an old Kerr 666 furnace/furnace that I use for melting aluminum. . It was easy to install and works great. I'm tempted to give 4 stars instead of 5 for the documentation, but that didn't stop my install, so I got 5. As others have said, the documentation is poor, but the connectors are clearly labeled on the device. Connect the AC line, thermocouple and + and - to the power management module. There has been some confusion about the red and blue wires on the thermocouple. With my red positive. Various videos on mypin controllers helped with the programming. I'm considering getting another one for the toaster.
