Description
The white Alarm.com ADC-T40K-HD-W Smart Thermostat HD uses a full-color touchscreen to make temperature, mode, fan, and system status easier to read at a glance. It supports compatible conventional, heat-pump, and dual-fuel equipment with up to three heating and two cooling stages.
A 24V AC C-wire is required for the always-on display and connected features. Humidifier, dehumidifier, and HRV/ERV ventilation support allow a single thermostat to coordinate compatible comfort equipment, while Z-Wave SmartStart and S2 simplify secure enrollment with an Alarm.com system.
Local scheduling is available only while the thermostat is not enrolled; after enrollment, connected schedules and scenes are managed through the platform. In a broader smart thermostat plan, confirm wire assignments and accessory terminals before power is applied, then test every stage independently.
