SAS919WHB Non-Programmable Boiler Thermostat Kit

SAS919WHB is designed for users who want simple, straightforward temperature control without schedules or programming. Simply set the desired temperature manually and the thermostat maintains it — no learning curves, no complex menus. Perfect for users of all ages, especially those who prefer a traditional, no-fuss approach.

SAS919WHB features large, responsive physical buttons that provide clear tactile feedback with every press. Unlike touchscreen models that may be less responsive to gloved or dry hands, physical buttons work reliably in all conditions — making operation effortless for everyone.

Engineered to work with virtually all standard boiler systems, including combi boilers, system boilers, and heat-only boilers. Whether it's a new installation or a retrofit project, SAS919WHB adapts to your existing system without the need for complex modifications.

Powered by standard AA batteries, SAS919WHB requires no wiring between the thermostat and the heating system. This makes it an ideal drop-in replacement for older thermostats in homes where running new cables is costly or impractical — significantly reducing installation time and cost.

SAS919WHB comes with a wall-mounting bracket and a tabletop stand, offering maximum placement flexibility for any room layout. Whether you prefer it mounted on the wall or placed on a shelf or desk, installation takes seconds without any tools.

SAS919WHB provides unified control for the entire heating system through a single thermostat. Unlike zone-based systems that require separate controls for each room, this model manages whole-home heating from one central point — simplifying operation while maintaining consistent temperature across all areas.
