Dependable 24-Hour Control for Sime Heating Systems

The Sime Clock Timer (6197707) is a robust hardware essential for the daily operation of your central heating. At ECO Heat Shop, we understand that maintaining your existing boiler is often the most sustainable choice. Replacing a sticking or failed timer with this genuine 6197707 unit ensures your boiler only fires during your set “ON” periods, significantly reducing unnecessary gas usage and lowering your home’s carbon footprint.

This mechanical programmer is favoured by engineers for its simplicity and long-term durability. Unlike digital interfaces that can suffer from screen bleed or software errors, the 6197707 provides a clear, physical representation of your heating schedule that remains easy to adjust, even in the dimly lit environments of a boiler cupboard or utility room.

Key Features & Professional Benefits

• Tactile Tappet Programming: The 24-hour dial features 96 individual segments (tappets), allowing you to fine-tune your heating cycles in 15-minute increments to perfectly match your daily routine.
• Integrated Manual Override: Features a central 3-position switch, allowing you to toggle between “Timed,” “Constant On,” and “Off” without disrupting your carefully set daily programme.
• High-Torque Synchronous Motor: Built with a reliable internal drive motor designed to provide accurate timekeeping in the high-temperature environment behind the boiler’s front panel.
• Easy “Plug-In” Installation: Designed as an integral unit that connects directly to the boiler’s internal wiring loom, ensuring a clean, flush-fit replacement for the original part.

Using an authentic Sime 6197707 timer ensures that your boiler’s internal electronics and safety protocols remain uncompromised. We offer fast UK delivery and expert technical support to help you maintain a high-efficiency, sustainable household.

Expert Tip: If you find that your boiler is staying on constantly or your clock is “losing time,” the internal motor gears may have worn down. This 6197707 unit is a direct replacement. Before fitting, ensure the boiler is isolated from the mains electricity. Once installed, rotate the dial clockwise to set the current time before pushing the tappets outwards for your required ‘ON’ periods.
