SAS920WHL Field-Proven Programmable Hydronic Thermostat

Heavy-duty tactile buttons and clear LCD layout provide positive tactile feedback and reliable, tamper-resistant daily operation in high-traffic environments.

Commercial-grade hydronic climate control at a highly competitive price point — making this thermostat a high-margin choice for bulk procurement, large-scale housing, and cost-sensitive bids.

High-precision 7-day scheduling (4 or 6 configurable segments per day) automatically reduces energy waste during unoccupied hours — ensuring fast compliance with green building standards.

Supports internal, external, or dual-sensor monitoring modes to enforce strict floor temperature limits — eliminating wood warping or tile cracking while reducing callback costs.

Automated anti-freeze mechanism and built-in pump-valve-boiler interlock logic protect hydronic loops from freezing — preventing pipe bursts in unattended or holiday properties.

Natively compatible with standard mounting boxes and supports both multi-zone underfloor manifolds and single-zone boiler retrofits — minimizing inventory complexity for distributors.
