Description
The Alarm.com ADC-T40K-HD Smart Thermostat is a powerful Z-Wave Plus-capable thermostat featuring a full-color HD touchscreen for simple and intuitive control. With mechanical wire detection and an Easy Setup Wizard, installation is streamlined, making it ideal for both professionals and DIY users.
Unlike standard thermostats, the ADC-T40K-HD combines a separate thermostat module (ADC-T40) and an HD display (ADC-T40-HD), which magnetically attaches for convenience. The thermostat itself connects to the HVAC wiring and communicates with the Z-Wave network, while the display houses the temperature and humidity sensors. This allows for flexible installation, including headless setups if needed.
When paired with a Z-Wave Plus controller, users can enjoy advanced automation features, energy-saving schedules, and remote access through the Alarm.com app. Whether you want to automate your HVAC system based on security system events or adjust your home’s comfort settings from anywhere, the ADC-T40K-HD delivers performance and convenience.
