When the ripple receiver detects a load-shed command, it closes contacts between R1 and R2 → KES timer opens internal relay contact between L IN and L OUT → Geyser stops. | | E2 | Battery low (below 2
A: Yes. Simply leave R1/R2 disconnected. The timer will still function as a standard programmable timer based on your ON/OFF events. | | Flashes “Ld” but grid is stable
