I have been running a herpstat pro on my rack system for the last 6 months or so. I just moved the rack to a new location, but left the settings on the herpstat the same. Now the herpstat is reading 120 at 0% power. My acurites inside the tubs is reading at 98. Any ideas on why it is now over heating? The herpstat is set to proportional and before I moved the rack was heating the flexwatt to 95 and around 88 in the tub.
