Review on 🕹️ Single-Titan Multi Function Controller by Patrick Matin

This controller works great 99% of the time. However, the remaining 1% killed almost all of the plants in my greenhouse. I called technical support about a malfunction: near the set temperature, the fan randomly happens to almost stop (about 4 seconds per revolution). The technician was unwilling to admit that I had a defective unit and insisted that my fan shut down due to thermal overload. As a retired engineer, I've oscilloscoped and extensively tested the Titan Mercury 4, as well as other controllers I've had on hand over the past few weeks. I'm 100% sure my fan isn't turning off, the controller just drops to a very low voltage for no apparent reason. It also doesn't overheat (because it's a comfortable 80 degrees in the greenhouse). I'll call Titan again.
