Has anyone else noticed the updates in the new KES Geyser Load Control Timer manual? I just installed the latest unit and spent the afternoon decoding the instructions so you don't have to. Mastering Your KES Geyser Load Control Timer: A

What’s changed: The interface is actually intuitive this time around, but the manual still has some dense "translation-ese." If you are struggling to set your load control, here is the crucial part most people miss on page 4:

• The "P" Setting: You have to set the current time before you touch the program button, or it defaults to midnight.
• Override Function: The new manual clarifies that the "Override" isn't just an on/off switch—it puts the unit into manual mode until the next scheduled timer event. This is huge for load shedding schedules.

If you’ve lost your paper copy, I highly recommend keeping a digital PDF of the manual on your phone. It makes troubleshooting those random blinking lights way easier!

Programming — Common Workflow

Assumption: model supports weekly programming with multiple events.

1. Enter programming mode (press and hold "Prog" or similar).
2. Set current time and day (use arrows or dial). Confirm DST if available.
3. Create events:
   • Select event number → set Start time → set End time → assign active days (Mon–Sun or presets like Weekdays/Weekend).
4. Repeat for additional events (e.g., two off-peak windows).
5. Set default state (e.g., OFF during peak hours).
6. Configure external control behavior:
   • If using utility load-shed input, set behavior to “shed on signal” or “ignore” depending on preference.
7. Save and exit. Verify LEDs show scheduled state; optionally run a manual test.

Common tips:

• Schedule heating to finish shortly before expected peak usage (e.g., morning shower times).
• Use shorter boost periods (10–30 minutes) to avoid excessive energy draw.
• For households with solar PV, pair schedule so heating coincides with midday solar production (if allowed by timer).

2. Key Features of the New KES Model

• Digital LCD Display: Shows current time, temperature (if sensor equipped), load status (On/Off/Limited), and active program.
• Load Control Input: Accepts signal from municipal ripple receiver or auxiliary contactor.
• Manual Override (Boost): Allows temporary geyser activation during a load limit event.
• Battery Backup: Retains time and settings during mains power failure (typically 72–100 hours).
• 8 Programmable Events: Set up to 4 ON/OFF cycles per day.
• Non-Volatile Memory: Saves settings even without battery.
• IP20 Rating: Suitable for indoor DB board installation.

Key Features

• Daily and weekly programmable schedules — multiple ON/OFF events per day.
• Load control / demand response compatibility — accepts external signals (e.g., from a utility or home energy manager) to shed or enable the load.
• DST auto-adjust and battery-backed clock — preserves schedule through power interruptions.
• Manual override / boost — temporary enable for immediate hot water.
• High-current relay or contactor drive — suitable for typical residential geysers (check model amperage rating).
• Status indicators — LEDs for power, relay state, and external control signal.
• Safety protections — anti-short-cycling, minimum off/on durations, and isolation between control circuits and mains.
