HELP!!!!!!!!! I have my reptitemp 500r with the larger UTH pluged in and it is turned all the way up, but it is not getting very hot. The smaller UTH that is plugged straight into the power strip is hotter. My digital temp gauge is reading around 75F & 57% humidity. Any reason why the UTH is not getting warmer, its been plugged up all day with no change. Please somebody help! Wife & I are getting our first BP this up coming weekend & I'm trying to get the tank just right.
