Title: Missing the paper manual? Here is the programming sequence.

Post: ⭐ 4/5 Stars – Works great once programmed.

The Tomzn TOVPD1-60-EC is a solid unit, but the manual is tiny and hard to read. For those installing it:

Programming cheat sheet:

Note: This is the 60A model. Make sure your wire gauge is at least 6 AWG (copper) or 4 AWG (aluminum).

The digital display is very accurate. If you see "E-03", your voltage is outside the programmed range. Just widen your U-Hi/U-Lo margins.

Would I buy again? Yes. But keep this post saved because the printed manual is microscopic!
