I bought this to regulate the temperature on a freezer that I use for home brewing. Compared to other devices, the price point was spot-on and it does exactly what I needed to.

I looked all over for a control like this one that could handle more than 10 amps, so I could use it with my electric space heater. It can automatically switch from heat to cool mode as the ambient conditions change throughout the day/night which is nice during those months when you start out in heating mode in the morning and are looking for some cooling by the late afternoon!

We were looking for something to better control temp w/o having to keep unplugging at outlet. So far it has worked phenomenal. Glad I searched outside my usual sources

Great for out little hobby greenhouse. Used both high & low temp alarm functions. Good product thus far.

Unit is operating well. Setup was a hassle. The written instructions were so small had to use a magnifier. Between steps unit would time out. Had to write out procedure and hang next to unit to set it up. You need to increase time out to 10 seconds between steps and have instruction text much larger letters.

ACF Greenhouses: I’m sorry you had trouble reading the manual. Surestat DT10 instructions with larger print are available for download in the item's description.
