Under tank heat pad help

[sidman24]

So I bought a thermostat for my under tank heat pad and I'm confused. When I scanned the temp of the surface it was reading about 100 degrees. So I set the temp on the thermostat at 90. My question is where should I stick the probe that came with the thermostat? I put it under the tank on top of the heat pad but it seems like it drops down to like 85... Then slowly rises... Then drops again. Like it can't stay right at 90? Am I doing something wrong? When I feel the ground at 85ish it hardly feels warm at all. Any advice would be appreciated!

Place the probe on the inside of the tank directly on top of the heat pad. Hold in place with clear packaging tape. Do not submerse in water. All thermostats are not created equal. You just need to calibrate it to the desired temp you want. Who cares what the dial says.

Cheaper thermostats work by turning the heat pad on and off to maintain a temperature so there will always be some variation as it cools when it it cut off and warms as it is turned back on. As long as it is within a 10º threshold then you should not worry about it.

What are you trying to heat?
