Be cognizant of the probe placement and be sure not to tape over the probe end. Check for dislodgement as well because the continuing sliding in and out of the tubs can affect the fixation and position of your probe. Periodically double check the settings of the day , month, and year programmed into the thermostat. Also the clock time should be set accordingly and to pm and or am. Different thermostats have various and different power settings. Most of all, it’s something that you will have to periodically double check. Congrats on the new quality equipment. I have two different rack systems C serpents and Reptile basics. 3 of each type and one hatchling rack by C serpents. For the most part , I have to occasionally go up or down a couple of degrees but 92F is my regular.
