SAS920XWHB Wi-Fi Boiler Thermostat

Set customized heating schedules for each day of the week to match your lifestyle and occupancy patterns. The intuitive programming interface allows for multiple time bands per day, automatically adjusting temperatures when no one is home to save energy and ensuring comfort when you return.

Built-in Wi-Fi module connects directly to your home router — no hub or bridge required. The dedicated APP allows you to monitor and adjust temperature, view energy reports, and manage schedules from anywhere via smartphone. Compatible with iOS and Android devices.

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, SAS920XWHB adapts to your existing system without the need for complex modifications.

Powered by standard AA batteries, SAS920XWHB 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.

SAS920XWHB 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.

SAS920XWHB 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.
