Timeguard STBT4 Description

The Timeguard STBT4 Suretime Electronic Boost Timer offers a straightforward and reliable way to control the duration that a connected load receives power. With a boost time range from 15 minutes up to 2 hours, this timer ensures that heaters or lights don’t get left on accidentally, helping you save energy and reduce running costs. The unit features a bright, illuminated boost button and easy push-button control, which cycles through the available time settings before counting down automatically.

Designed to fit a standard BS flush or surface wall box with a minimum depth of 25 mm, the STBT4 is compact and installer-friendly. The LED indicators show the approximate time remaining on the countdown, and the countdown can be cancelled mid-cycle by pressing the boost button again. Typical applications include immersion heaters, towel rails, room heaters and other compatible loads, making it a versatile addition to both domestic and commercial electrical systems.
