Okay I just bought a second BP as my first one was doing great but the issue I am getting is I only have 1 probe which is measuring the heat on one of the heatmats. The heatmat that has the probe is at the correct temperature as it should but the one without the probe is not at the correct temperature and its higher because when the probe detects its at the correct temperature it will switch both off and if its not it will switch them both on which causes the one without the probe to be hotter and I'm not sure what to do other than buying a new thermostat...? Got any ideas?
