How it works
Set the required countdown time using the up/down buttons, then press Start. The internal contacts switch and the timer begins counting down digitally. When the set time expires, the display returns to zero and the contacts switch back.
This gives you a more precise, modern alternative to older mechanical timing systems, while keeping operation simple and easy to understand.
Key advantages over older mechanical timers
Better environmental protection: The BCT2S features an IP65-rated enclosure, making it more resistant to moisture and dust than many older timer designs.
Easier to read and set: Instead of manually setting a mechanical dial, you can adjust the timer using simple push buttons and a clear digital display.
Improved reliability: Electronic operation helps reduce the wear and inaccuracy often associated with aging mechanical timers.
Simpler upgrade path: The included conversion disc helps make replacement easier when upgrading from compatible ISGUS-style mechanical timer installations.
Important compatibility note
