At 9 PM, with a headlamp and a screwdriver, Nina opened the old meter box. The old timer was indeed a KES—a rusted relic. She swapped in the new KES-LCT-9000.
Then came the programming.
The manual said: “To set Load Shedding Profile P1, press MODE for 3 seconds until ‘Prog’ flashes. Use UP/DOWN to set ON time. Press SET to confirm. Repeat for OFF time.”
Simple, right? Wrong.
She discovered that the KES had four overlapping modes:
At 10:17 PM, she accidentally enabled Mode D + Eskom-Sequencer. The geyser clicked on for 17 seconds, off for 43 seconds, then on again—a frantic staccato. The manual’s flowchart on page 27 showed a loop labelled: “If erratic cycling: Perform factory reset (see Appendix B: Prayer).”
The KES geyser load control timer is an indispensable tool for managing energy costs and complying with municipal load reduction schemes. The new models take the guesswork out of scheduling, while giving you manual override power when you really need a hot shower.
Keep this manual accessible – either printed inside your distribution board cover or saved as a PDF on your phone. And remember, while programming is user-friendly, installation must always be left to a qualified electrician to ensure safety and warranty compliance.

The KES Geyser Load Control Timer (specifically model ISG1201) is a specialized device designed to manage water heating and reduce energy bills by preventing operation during peak demand periods. Unlike standard digital timers that require complex manual scheduling, the KES model uses pre-programmed operating profiles to simplify user interaction. Understanding Your KES Geyser Timer (ISG1201)
The device features three primary LED status indicators and four preset profiles: Green LED: Indicates the mains power is ON. Red LED: Indicates the geyser itself is ON and heating.
Flashing Blue LED: Indicates the currently active timer program. Operating Profiles & Programming
The KES ISG1201 includes four factory-set profiles. To select a program, use the Program Select button to cycle through them. Blue LED Pattern Function & Operating Hours Prog 1 1 flash / second
Default Mode: Always ON, but automatically locks out during morning and evening peak hours (Monday–Friday). Prog 2 2 flashes / second
Solar Geyser Mode: Optimized for solar setups. OFF from 08h00 to 15h00 and during all peak demand times. Prog 3 3 flashes / second
Off Mode: Geyser is OFF at all times. Manual override is still available. Prog 4 4 flashes / second
Maximum Savings: ON for only 6 hours on weekdays and 12 hours on weekends. Highly restrictive to minimize costs. Manual Controls & Override
If you need hot water outside of your selected program's schedule, you can use the Override feature.
Activation: Press the Override button to switch the geyser ON immediately.
Duration: The override typically lasts for one hour (or until the next programmed event).
Restrictions: Most KES models block overrides during peak demand times (typically 06:00–08:00 and 18:00–20:00) to comply with load-balancing standards. Installation & Setup Instructions
Warning: Installation involves working with your distribution board (DB) and should be handled by a qualified professional.
Turn Off Power: Switch off the main power and the specific geyser isolator before starting.
Mounting: The unit can be mounted on a DIN Rail inside your DB or a surface-mounted enclosure. Wiring: Connect the Live (L) input from the geyser circuit breaker. Connect the Neutral (N) wire from the DB's neutral bar.
Connect the Load out (bottom of controller) to the geyser wire.
Reset: After powering up, it is recommended to press the Reset button with a small pin to ensure the unit starts in its default state. Common Troubleshooting
Flashing Lights / No Hot Water: If the Blue LED is flashing but the Red LED never turns on, check if you are currently in a "Peak Time" lockout or if you have accidentally selected Program 3 (Always Off).
Battery Backup: The controller features a 60-day battery backup to maintain your settings and clock during load shedding or power failures.
Clock Verification: On some versions, you can verify the Real Time Clock (RTC) by holding the Override and Program buttons together. The new KES timer has a load limit
