You probably won't get great regulation that way. For RHP I usually suggest to tape the probe tip flat on the panel. The problem with putting in the corner is that is where the thermostat is getting its reading from so by being that far away and in a corner no less you have dramatically slowed the reaction time of the thermostat. When it starts heating up you will have a build up of heat in the top of the enclosure. By the time the heat gets to the lower probe location and the thermostat dims down or turns off you still have all this built up heat above which can be at a higher temp. Then your temperature continues to climb even though there is no power going to your heating device. Then the reverse happens on the down swing. It starts to cool off and goes below your setting but now it has to heat up the top of the enclosure again. The temp continues to drop as its playing catch up and you end up in this repeating see-saw temperature swing. That is my experience anyway. Then usually I have a panic email in my inbox. :^) I then recommend a regular thermometer with its probe at floor level to monitor the floor temp and adjust the thermostat (with its probe next to the heating device) until you get a good middle ground between upper temps and lower temps. Expect that the upper temps (and thermostat setting) will be much hotter than the floor temp.
