The SAS965MTW 4-Inch Color Touchscreen BACnet DX Thermostat is a premium controller for sophisticated multi-stage DX systems, blending a vibrant 4-inch color touchscreen with BACnet MS/TP communication for native BMS interoperability. As part of the MTW Series DX Thermostats, it delivers precise staging logic, adjustable protection timers, and an intuitive user interface—empowering facility managers with centralized visibility and guests with effortless comfort control.

Advanced staging algorithm orchestrates up to multiple compressor and heat stages with fine-tuned PID logic, ensuring stable space temperature under varying loads while preventing overshoot and unnecessary cycling.
Field-adjustable deadband and anti-short-cycle restart delay parameters allow tailoring to specific equipment tolerances, preventing nuisance cycling, reducing mechanical wear, and extending system service life.
High-definition capacitive touchscreen delivers crisp visuals and fluid touch response, offering intuitive temperature adjustment, schedule programming, and system status checking—even in dim ambient lighting.
Accelerated UI customization within 7 days enables brand-specific splash screens, color palettes, and layout adjustments, allowing hoteliers and OEMs to differentiate their product identity without delaying time-to-market.
Snap-fit mounting mechanism eliminates the need for screws or specialized tools during installation. The detachable front module clicks securely into the backplate, cutting installation time and reducing on-site labor costs.
Built-in OTA capability simplifies remote firmware upgrades via BACnet or network connection, eliminating costly on-site firmware refresh campaigns and ensuring thermostats stay current with feature enhancements and security patches.
