What is dry mode and wet mode ?

The control panel supports “dry mode” and “wet mode” by using the jumper. For “wet mode”, short 2-3 and 4-5 terminals. The control panel and the lock use the separate power supply. One is connected with +12V and GND of POWER interface (for the control panel), the other is connected with V+ and V- of LOCK interface (for the lock). The factory default jumping is set as dry mode.
