Im just kind of pissed off and dont know what else todo I know to some of you this could be a no brainer but I need to have my rack temps perfect for my new babys next week. thank you Brandon
1) The probe goes directly on the heat source...
2) reduce the thickness of the substrate by about half...
3) Make sure the thermostat is in the "Heat" mode...
4) Make sure the differential temp is no more than "2"...
