Description
The black Alarm.com ADC-T40K-HD Smart Thermostat HD combines a vivid color touchscreen with control for compatible conventional, heat-pump, and dual-fuel systems up to three heating and two cooling stages. The dark bezel gives the display a deliberate, high-contrast appearance on modern interiors.
This model requires 24V AC power and a C-wire. It can coordinate compatible humidifiers, dehumidifiers, and HRV/ERV ventilation equipment, while Alarm.com enrollment adds remote setpoint control, schedules, scenes, and HVAC health information.
Z-Wave SmartStart and S2 support secure inclusion, but system behavior still depends on correct wiring and platform programming. Verify each heat, cool, fan, auxiliary, and accessory terminal against the HVAC equipment before commissioning, especially on dual-fuel systems.
