The LavaTap Pro Controls 7-Day / 1-Channel Digital Timer is a reliable, user-friendly solution for replacing older Honeywell heating controllers. Designed specifically to fit the same 6-terminal backplate as the Honeywell ST9100C, ST9100A, ST6100A/C, it clips directly into place without the need for rewiring (FOR THE ST7100 REWIRING IS NEEDED). This makes it the ideal drop-in replacement for homes already equipped with these legacy systems.

Once installed, the timer allows full customisation of your heating schedule with up to three ON/OFF cycles per day. It supports 24-hour, 5/2-day and full 7-day programming formats, offering flexibility for everyday routines. Commonly used with combi boilers and single-zone heating setups, this programmer is trusted by landlords, engineers, and homeowners for its simplicity and reliability.

The large backlit display features a clear, text-based interface that guides users through setup and shows live system status. Features such as Boost Mode, Manual Override, and Holiday Mode provide real-world convenience for modern households. All settings are retained even during power cuts thanks to the built-in memory, and the internal clock adjusts automatically for daylight saving time.

Built by Resideo, the company behind Honeywell Home and Honeywell's home heating business until 2018, the LavaTap Pro Controls timer delivers long-lasting performance and ease of use at an affordable price. It is backed by a 3-year warranty and is engineered to meet the demands of UK heating systems with quick, stress-free installation.
