Product Overview
The ADC-T40K-HD is Alarm.com's high-definition colour-display smart thermostat in white. Beyond the better screen, it sits inside the Alarm.com automation engine — so heating follows the arming state, and the HVAC can be shut down automatically on a smoke event rather than pushing smoke around the building.
Key Features
- High-definition colour display with clear at-a-glance status
- Managed from the Alarm.com app alongside the security system
- Automation rules tied to arming state and sensor events
- Automatic HVAC shutdown on a smoke alarm event
- Schedules, geofencing, and remote adjustment
- Energy reporting through the Alarm.com platform
- White finish
