SAS816WHB Rotary Dial Manual Boiler Thermostat

SAS816WHB is designed for users who want the simplest possible temperature control. Turn the dial to your preferred temperature and the thermostat takes care of the rest — no schedules, no menus, no learning curve. This makes it an ideal choice for rental properties, holiday homes, guest rooms, and budget-conscious new builds where straightforward control is all that's needed.

The large, ergonomic rotary knob provides intuitive, precise temperature adjustment with a satisfying tactile feel. Simply turn clockwise for warmer or counterclockwise for cooler — no buttons to press, no menus to navigate. The clearly marked temperature scale allows for quick, accurate setting at a glance.

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, SAS816WHB adapts to your existing system without the need for complex modifications.

Powered by standard AA batteries, SAS816WHB 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.

SAS816WHB 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.

SAS816WHB 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.
