the reptitemp is no more than an expensive, glorified rheotstat. If you want a reliable, accuate, thermostat, i would recomend Johnson Controlls, Helix, Ranco, Herpstat or Spyder Robotics.
I had a reptitemp 500R, and replaced it within weeks because it was TERRIBLE. there is no temperature setting, just a dial. Thermostats dont read humidity, for that you need a hydrometer. Accurite sells a thermometer/hydrometer combo with a probe. you can find it at walmart, target, lowes, etc and its less than 15 bucks. Great investment.
