Review on DIGITEN DTC101 Digital Temperature Controller - Greenhouse Thermostat Plug for Heater, Heat Mat, Aquarium, Reptile Incubation, Homebrewing - Heating & Cooling Mode by Elijah Harvey

I bought 2 of these. It might be better to control the heat. But it was not suitable for cooling at all. Put on a kegerator to control the cooling and turn-on temperature. Set it to 38 or 36.5. Well, it kept falling below the cutoff at 34 or 35. And the alarm kept going. So he raised the temp to 39 and stopped at 36.5. Same problem if you want to go to 34 or 35 before knocking out the kegerator. return both. Bad call on my part for temporary control.
