Review on Citphto Controller Universal Electronic Regulator by Dana Mahendra

Installed on our awesome RV Fan. Regular controllers only have 3 speeds. Tried a PWM speed controller and it was very noisy. Only gave it 4 stars as it needed a few mods to make it fit.1. Modification, removal of the back panel through which the wires pass. This helps create clearance to fit within the space provided.2. Drill a hole in the back, being careful not to hit any wires, capacitors, or other components inside.3. Move the grommet from the back plate to the drilled hole and feed the wires through the grommet again. (This will help give more space to put everything. 4. Connect the wires as shown in the diagram, also use a fuse to protect the circuit. 5. Check if the fan is working properly. This controller can't change the direction of rotation of the fan, but it has a position on the dial. We only use the fan as an exhaust fan, so it doesn't matter to us. Otherwise, you could use the reversing switch that's on the Fantastic Vent, but I didn't choose it.
