Settings Via The Rotary Switch - Victron energy MPPT 150/70 Manual

5.1.2. Settings via the rotary switch

The rotary switch can be used to select eight pre-programmed battery charge algorithms.
Use a small flathead screwdriver to turn the rotary switch. The arrow indicates which setting number has been selected.
The table below indicates the charge algorithm and charge settings for each rotary switch position.
Turning the rotary switch will override the charge settings including settings that were made with the
VictronConnect app or with the display. Likewise, if charge settings are changed with the VictronConnect
app or the display, this will override the rotary switch setting.
