Its primary function is to ensure the geyser element is only switched on during specific times of the day. By heating water only when needed (for example, from 4:00 AM to 6:00 AM for morning showers and 5:00 PM to 7:00 PM for evening use), you prevent the element from cycling on and off throughout the day and night, significantly reducing electricity consumption. kes geyser load control timer manual
