It works great when it wants to, but it consistently gets locked up. The screen stays black and Stelpro support describes it as thermal protection, so that it doesn’t overheat and become a fire hazard.Bad news, it locks up all the time, only can resolve it by flipping the circuit breaker. I’ve tried 3 different heater circuits, all with the same issue. It’s passive thermal dissipation still isn’t good enough when installed in a drafty hallway.Good luck and best wishes to anyone that buys this product. ### ⭐ 1.0 out of 5 stars Frequently locks up, tech support non-responsive *by C***T on Reviewed in the United States on November 5, 2020* I purchased this and the auxiliary unit to control base board heaters. The first problem I noticed is that the weather for my house (based on location) was not accurate at all. The auxiliary unit had trouble keeping sync with this base unit. After three months this unit started to lock up and became unresponsive. Sometimes this would happen when the heat was called at 100%. The lock up prevented the thermostat from lowering the temperature at night. We would wake up to a sauna! The only way to reset this unit is to turn it off at the breaker. This unit continues to lock up and requires a circuit breaker reset every three or four days. I called tech support and got no answer. I also sent multiple emails to stelpro and received no answer. I expect so much better service from a Canadian company! I cannot continue to risk leaving a runaway thermostat in service and have replaced it with another brand which is 100% reliable (although very basic). I like the features and the programming of this unit but have found it completely unreliable and causing waste by running excessive heat outside of schedule. I highly recommend that you avoid this unit and the auxiliary units. ### ⭐⭐⭐ 3.0 out of 5 stars Fine Thermostats *by C***G on Reviewed in the United States on February 1, 2020* Setup is very easy, and connecting additional thermostats to the controller is also straightforward. The geofencing feature is pretty hit or miss, and misses often enough that I just use a programmed schedule rather than relying on geofencing. My biggest problem with these is that the ambient temperature they display isn't the real ambient temperature. They measure the temp, then use some internal algorithm to approximate the temperature in the middle of the room. In my case, the approximated temperature is a few degrees higher than the actual (measured with a thermometer). Thats easy enough to plan around, its just frustrating that the temp displayed isn't the real temp. I asked stelpro tech support to see if there was a way to turn that feature off but was told no. For a positive, the energy tracking feature is awesome, and is a lot of help in understanding my energy bill. --- ## 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.fr/products/102916640-stelproasmc402-smart-home-wi-fi-controller-thermostat-adds-maestro-connectivity](https://www.desertcart.fr/products/102916640-stelproasmc402-smart-home-wi-fi-controller-thermostat-adds-maestro-connectivity) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-04-25*
