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 ### ⭐⭐⭐⭐⭐ Review *by K***R on January 12, 2026* ### ⭐⭐⭐⭐⭐ Review *by E***S on August 20, 2020* ### ⭐⭐⭐⭐⭐ Review *by J***. on April 24, 2026* ## 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.hr/products/32710514-temperature-controller-1650w-15a-btc211-dual-digital-outlet-thermostat-plug](https://www.desertcart.hr/products/32710514-temperature-controller-1650w-15a-btc211-dual-digital-outlet-thermostat-plug) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-17*
