Dynamic Load Management

RDC Charger supports power consumption (current draw) control to prevent circuit breaker tripping (overloading).
Overloading causes multiple high-energy appliances working at the same time, such as an oven, dishwasher, heat pump and EV charging.
RDC Charger monitors a current draw by appliances and in real time allocates (limits) available capacity allowing them to run without overloading.
NOTE: Power sensor must be mounted so that it can measure power & current on grid (power supply for object/home).

Procedure to activate Dynamic Load Management is as follows:

HEMS Configurator → settings → Virtual grid PS must be disabled (1)

Wire PM1-E-D or PM3-E-D to WM-1 module (set address to 150 or use default address 149)

HEMS Configurator → settings → select WM/WR pairing button and follow WM/WR pairing instructions (2) (3)

Power sensor is detected. Add it to grid position (4)

Power sensor configured successfully (5)

HEMS Configurator → DLM, enter allowed current value of grid fuses (6)

make sure to configure correct phase order (7), otherwise dynamic load management may not work properly

select limiter priority for RDC Charger (8): no limiter, limit last (last to be limited), limit second, limit first (first to be limited)
