KES Geyser Load Control Timer (ISG1201) is an energy-saving device designed to automatically disable your geyser during peak electricity demand periods. It is pre-programmed to block power during standard morning (06h00–08h00) and evening (18h00–20h00) peak times from Monday to Friday. Key Features & Indicators Peak Load Lockout
: Automatically prevents operation during high-demand hours to reduce costs. LED Status Lights : Mains power is ON. : Geyser is currently receiving power (ON). Flashing Blue
: Indicates the currently active program (e.g., 1 flash for Prog 1, 2 flashes for Prog 2). Manual Override
: Provides a 1-hour manual heating window outside of peak times. Programming Guide The ISG1201 offers four pre-programmed profile options: Program Selection : Press the "Programme Select"
button to cycle through options. The blue LED will flash to confirm your choice (e.g., 2 flashes for Prog 2). Profile Options Prog 1 (Default)
: Always ON except during Monday–Friday peak times (06h00–08h00 and 18h00–20h00).
: OFF from 08h00 to 15h00 and OFF during standard peak times; ideal for solar geyser setups.
: Permanently OFF, though manual override is still available outside of peak times. Manual Override : Press the "Override"
button to heat water for exactly 60 minutes. This function is disabled during peak lockout hours. Installation Safety Professional Installation : This unit must be installed by a qualified electrician
as it involves high-voltage wiring in the distribution board. : It can be mounted on a
inside an electrical panel or surface-mounted in a ceiling cavity. Basic Wiring
: Red (Live) and Black (Neutral) wires from the geyser connect to the timer's output terminals (L2 and N2), while the input comes from the main geyser breaker. Usage Tips Temperature Setting
: For safety and to prevent bacterial growth, ensure your geyser's internal thermostat is set to at least Verification : After power is restored, check that the is solid and the is flashing according to your desired program. or help selecting the best program for your household's schedule?

Efficient Energy Management: Your Comprehensive KES Geyser Load Control Timer Manual
Managing energy consumption is no longer just about saving money—it's about sustainability and extending the life of your appliances. The KES Geyser Load Control Timer is a premier solution designed to give you total command over your electric water heater.
This manual provides a detailed walkthrough of the new features, installation steps, and programming instructions for the latest KES model. 1. Introduction to the KES Geyser Timer
The KES Load Control Timer is a heavy-duty digital switch specifically engineered to handle the high inductive loads of geyser elements (typically 2000W to 4000W). By scheduling your geyser to run only when needed, you can reduce your electricity bill by up to 30%. Key Features of the New Model: High Load Capacity: Rated for up to 30A/4400W.
Internal Battery Backup: Saves your settings during power outages (load shedding).
LCD Display: Clear, easy-to-read interface with real-time clock.
Manual Override: Instantly toggle between "Auto," "Always On," or "Always Off." Multiple Programs: Up to 16-20 ON/OFF cycles per day. 2. Safety Precautions
WARNING: Installation involves working with high-voltage electricity (230V AC).
Turn off the main power at the distribution board (DB) before starting.
Ensure the wire gauge used is appropriate for the geyser’s wattage (typically 2.5mm or 4.0mm).
If you are not a certified electrician, please consult a professional. 3. Installation & Wiring
The KES timer is designed for DIN rail mounting inside your distribution board or a dedicated weather-proof box. Wiring Diagram Basics: KES Geyser Load Control Timer (ISG1201) is an
Input (Live/Neutral): Connect the incoming power from the geyser circuit breaker to the "Input" terminals (usually marked L and N).
Output (Load): Connect the wires leading to the geyser to the "Output" or "Load" terminals.
Earth: Ensure the earth wire bypasses the timer and remains connected directly from the source to the geyser. 4. Programming the Timer (Step-by-Step) Step 1: Initial Reset
Before programming, use a small pin to press the 'Reset' button. This clears the memory and prepares the device for fresh settings. Step 2: Setting the Current Time and Day Hold the 'Clock' button.
While holding 'Clock', press the 'Day' button to select the current day of the week. Press the 'Hour' and 'Min' buttons to set the current time. Release the 'Clock' button. Step 3: Setting ON/OFF Programs
Press the 'Timer' (or 'P') button. You will see "1 ON" on the screen.
Press 'Day' to select the days you want the geyser to turn on (e.g., Monday-Sunday, or weekdays only).
Press 'Hour' and 'Min' to set the start time (e.g., 04:00 AM). Press 'Timer' again. You will see "1 OFF."
Set the time you want the geyser to turn off (e.g., 06:00 AM).
Repeat for "2 ON/OFF" if you need a second session in the evening. Press 'Clock' to save and exit. 5. Understanding the Manual Override
The 'Manual' button allows you to cycle through three modes: ON: The geyser stays on indefinitely (ignores programs). AUTO: The timer follows your scheduled programs. OFF: The geyser stays off indefinitely.
Pro Tip: Look for a small indicator on the screen. If you set it to "Auto," ensure the current state matches your schedule (e.g., if it's 10:00 AM and your schedule is OFF, make sure the indicator says "Auto Off"). 6. Troubleshooting Common Issues Comparison to Alternatives | Feature | KES New
Display is blank: The internal battery may be flat. Leave the unit connected to power for 10 minutes to charge. If it stays blank, press Reset.
Geyser doesn't turn on in Auto: Check if the "Auto" indicator is visible. Also, ensure your "ON" and "OFF" times don't overlap.
Timer loses time: This usually indicates the internal backup battery is reaching the end of its life (typically 3–5 years). 7. Recommended Energy Saving Schedule
For maximum efficiency, consider this "New" standard schedule:
Morning: ON 04:30 | OFF 06:30 (Hot water for morning showers)
Evening: ON 17:00 | OFF 19:00 (Hot water for dishes and evening baths) Mid-day: Keep OFF to avoid "standing heat loss."
By following this KES Geyser Load Control Timer Manual, you ensure your home stays comfortable while your energy footprint stays small.

The KES Geyser Load Control Timer has been a staple in South African homes (and other regions with load shedding or time-of-use tariffs) for years. The new manual model retains the rugged, mechanical design but introduces a few subtle improvements over older versions—namely a clearer dial face, sturdier pins, and a more responsive override switch. This device is designed to automatically switch your geyser on/off at preset times, preventing unnecessary heating during peak electricity rates or overnight.
⚠️ DANGER: Electrical hazard. Geysers operate at 220V-240V AC (or 110V in some regions). Installation and wiring must be performed by a registered electrician. Incorrect wiring can cause electrocution, fire, or damage to the timer and geyser.
Before programming or handling the timer:
The KES geyser load control timer is an electronic time switch designed specifically to manage the load on your electric water heater. Unlike a simple timer that only switches on/off based on time, a load control timer interfaces with your utility’s ripple control system or internal load limiter. It prevents the geyser from drawing power during peak grid demand or when the household exceeds a pre-set load limit (e.g., 60A or 80A).
The new generation KES timers come with updated firmware, a larger LCD screen, and more intuitive buttons compared to legacy models.
