He especially loves the dual outlet feature that allows him to both heat and cool as needed, which makes controlling the environment much easier. The setup was straightforward, and the digital display is clear and easy to read. Having the ability to automatically regulate temperature without constantly checking or adjusting it has been a huge convenience. Overall, this controller is reliable, efficient, and takes the guesswork out of temperature control. If you need precise heating and cooling management, this is a solid and dependable choice. Review: After two years it's still working! UPDATE AT 4 YEARS FIVE YEARS!!! - I looked at many controllers before settling on this one. First I needed one that would handle a 15,000 btu window a/c so that put many of them out. Between the rest, I ended up choosing this one. Very happy with this! It's pretty easy to set and the only reason I say pretty easy is because I have to think backwards since you set the shut off temp first (for a cooling appliance) and then add the number of degrees to that for when it cuts on. Probably easy for most everyone else but me. Still, it's an easy press of the button to set the on and off temp. It's got a nice long power cord and a nice long temperature probe cord which is very handy for me. It's worked perfectly all summer and we've had a couple of power outages. It also has a compressor delay function which is helpful. I'd buy this again if I needed another and have recommended it to a few friends. UPDATE: After two full hot summers running my large window a/c unit, and now being used to turn on/off two heat lamps I have to say I'm more than pleased with this unit. This past summer it would trip it's breaker occasionally and I thought perhaps it was the controller but later realized my old window a/c unit was off and on pulling too much power at startup coupled with periods of too much voltage spikes and dips on my line after the wind turbines were powered on all around me. It's running the heat lamps perfectly and the temp probe reads spot on with another thermometer probe I have hung next to it so I can read the temperature from inside. I highly recommend this unit. UPDATE at 4 years: Still no problems or complaints! This thing just keeps on working perfectly and spot on with the temps and controlling whatever I have plugged into it. I first thought it was a bit expensive when I purchased it but now I see that it's worth every penny and more. Don't hesitate to buy this if you have any needs at all for controlling a heating or cooling device. UPDATE AT 5 Years: Still going strong and reliable as ever. I count on this to keep my water lines from freezing in the rv basement area and it has it's work cut out for it for several months of the year, running two heat lamps. Seems perfectly on temp. Definitely a great purchase! ## Features - Simplified Design---Plug and play, easy to set.

Though I have not tried it. This is an excellent reliable product! **Q: What size screw do you use for mounting it to the wall? Must have a thin head** A: Just try and find screws with a <1/4" diameter head and flat, good luck, they don't specify screws by head size. WTH these don't come with any hardware, IDK. **Q: Does this Temp controller have solid-state relays or mechanical contacts?** A: I'm sorry, I am not a technical person. All I can tell you is - I set the parameters on the controller to keeps my greenhouse between 62 and 66 and it does all day and all night. If the temperature goes above 66 the controller will not come on until it drops to 62. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Dependable Temp Control *by K***R on January 12, 2026* My husband says this temperature controller works great and does exactly what it’s supposed to do.

The instructions are fairly easy to get through, and it's easy to program. I did have a "hiccup" in my unit, but when I emailed the company about it, they got back to me in a couple of hours with the solution, and the solution worked just right! So in addition to the good unit they sell, they back it with great customer service. The one issue I have with this unit is that its thermostat is wildly off every morning for some reason, registering temperatures far higher than I know is correct, at least at times. I put two other digital thermometers next to this unit, and most of the time their temperature readings were lower and more accurate to the "feel" of the room climate than the Bayite unit. However, before mid-day for some reason, all thermometers had the same temperature reading. The Bayite unit just regularly reads temps that are not accurate, especially in the morning for some reason, but "corrects itself" within hours. I did not deduct a star from this review because of that issue, since the unit does "balance" itself by mid-morning to agree with other temp readings. Aside from that, it's a really solid product and works very well, backed by very efficient customer service. ## Frequently Bought Together - bayite Temperature Controller 1650W 15A BTC211 Dual Digital Outlet Thermostat Plug, Pre-Wired, 2 Stage Heating and Cooling Mode, 110V - 240V, Fermentation BBQ Reptile Aquarium - bayite NTC 10K Temperature Controller Probe Sensor with 3.5mm Audio Plug 9.8ft Long - DIGITEN Digital NTC 10K 3950 Waterproof Temperature Sensors Temp Probe 6 Feet(2m) for Thermostat DTC101 DTC102 DTC151 Sensor Replace --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/32710514-btc-211](https://www.desertcart.be/products/32710514-btc-211) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-03*
