The ISG1201 comes with four selectable profiles indicated by a flashing blue LED:
Prog 1 (Default): Always "ON," but automatically switches "OFF" during peak times (Mon–Fri, 06:00–08:00 and 18:00–20:00). kes geyser load control timer manual new
Prog 2: "OFF" from 08:00 to 15:00 and during all peak times. Ideal for solar geyser setups.
Prog 3: "OFF" at all times by default, except for manual overrides. This is also suitable for solar applications.
Prog 4: "OFF" during specific blocks: 00:00–03:00, 08:00–15:00, 20:00–24:00, and all peak times. Key Controls and Indicators
Programme Select Button: Used to cycle through the four profile options.
Override Button: Provides a 1-hour manual bypass to heat water immediately using the geyser's standard thermostat.
Note: The override is only available outside of designated peak hours. LED Status Lights: Green LED: Mains power is present. Red LED: The geyser is currently receiving power ("ON"). | Error Display | Meaning | Solution |
Flashing Blue LED: Indicates the currently active profile (e.g., 2 flashes = Prog 2). Installation Basics
The unit can be installed on a DIN rail inside an electrical distribution (DB) panel or surface-mounted, often in a ceiling cavity near the geyser isolator.
Wiring: Requires a 220V connection to Live (L) and Neutral (N) terminals. The geyser's load wire is then connected to the "Load Out" terminal.
Professional Requirement: It is highly recommended that a qualified electrician perform the installation to ensure safety and insurance compliance.

Because the phrase "kes geyser load control timer manual new" suggests you are looking for documentation for a specific device that may not be widely available in a digital format, I have compiled the most useful content derived from standard KES Geyser Timer functionalities.
This guide covers the standard setup, programming, and troubleshooting for KES Geyser Load Control Timers. Most models (such as the popular KES-90B or digital variants) follow similar logic.
In the era of rising electricity costs and increasing pressure on national power grids, load shedding and load limiting have become household terms—especially in regions like South Africa, where utility providers use ripple relays and load control timers to manage demand. The KES Geyser Load Control Timer has emerged as a critical device for homeowners and businesses looking to automate their geyser (water heater) operation while complying with municipal load control regulations.
If you have just purchased the new KES model or are struggling to understand an existing unit, this long-form manual will walk you through everything: from installation prerequisites, programming steps, troubleshooting, to advanced energy-saving tips.
