Review on Origin Digital Elitech STC-1000 Temperature Controller - 110V Centigrade Thermostat with 2 Relays by Gus Gutierrez

Maybe it's me, but there weren't any wiring instructions so it seemed a bit overly complicated. However, once plugged in, it seems to do its job. It is used for more accurate temperature control in my 75 gallon tank. As it ages the internal thermostat often gets stuck in opposition and this will help reduce that anxiety and give me a good digital readout for more accurate temperature tracking.
