I had one set up like that so I put the proble under the stuck on heat mat and made sure the probe was touching the heatmat ... Works prefectly . Just have a digital temp gun to check the surface temps and adjust the thermostat accordingly ..
So, you sandwiched it inside the heat mat up against the glass?
I have a digital temp/hygrometer with a probe, is that fine because that's all I have right now?
