 +====== 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 home/facility).
 +
 +Procedure to activate Dynamic Load Management is as follows:
 +  * [[wiki:20_rdc_charger:30_software:start#hems_configurator|HEMS Configurator]] -> settings -> Virtual grid PS must be disabled (1)
 +  * Wire [[wiki:20_rdc_charger:15_hardware:20_pm1-ct|PM1-E-D-CT,]] [[wiki:20_rdc_charger:15_hardware:21_pm3|PM3-E-D]] or [[wiki:20_rdc_charger:15_hardware:21_pm3-CT|PM3-E-D-CT]] to [[wiki:20_rdc_charger:25_wiring:start#wireless_power_sensors_wiring|WM-1]] module (use default address 149 or manually set address to 150)
 +  * HEMS Configurator -> settings -> select WM/WR pairing button and follow [[wiki:20_rdc_charger:35_commissioning:03_wr_wm|WM/WR pairing instructions]] (2) (3)
 +{{wiki:20_rdc_charger:hems_config_dynamic_01.png?direct&800|}}
 +  * Power sensor is detected. Add it to grid position (4)
 +{{wiki:20_rdc_charger:hems_config_dynamic_02.png?direct&800|}}
 +  * Power sensor configured successfully (5)
 +{{wiki:20_rdc_charger:hems_config_dynamic_03.png?direct&800|}}
 +  * 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)
