Review on 🔧 Enhance Control Precision with RioRand Adjustable Reversible Reversing Controller by Shahed Cleveland

I had a problem with condensation in the cabinets in our RV in cold weather (15 degrees), even with the cabinet doors left open and the dehumidifier running. I installed 2 packs of 40mm x 40mm x 10mm 4010 12v covered with a 40mm black grille/finger guard (2 pack) and controlled by a RioRand DC motor speed controller 6v 12v 24v 28b , 3A, 80W. This circulates enough air in the cabinets to solve the problem of condensation and is virtually silent. We can use the motor speed controller to turn on/off the fans or set the fan speed to the quietest/lowest speed that solves the condensation problem.
