Designed by Building36 with easy installation in mind, the T25 has flexible wiring options that allow it to operate on battery power if no C-wire is present. This eliminates the need to run wires or use a retrofit kit. It also includes auto-configuration with wire detection. Full integration with the Alarm.com platform enables remote control of the thermostat and customizable automation options. Enrolled customers receive monthly reports featuring personalized efficiency tips, key metrics like overall run time, and updates on any system issues.

The T25 additionally supports participation in demand response programs, giving customers incentives if they allow temporary adjustments to their thermostat settings during periods of peak demand. The T25 also enables Pro HVAC Monitoring, connecting customers with local service providers when the system detects anomalies. Both customers and their preferred HVAC professionals are notified instantly, and service appointments can be requested directly from the mobile app. Service providers also benefit from these programs by receiving recurring revenue for every customer enrolled.
