VisionPRO 8000 Smart

Honeywell Home VisionPRO 8000 Smart Thermostat

The Honeywell Home VisionPRO 8000 Smart is a Wi-Fi-enabled programmable thermostat designed to manage compatible residential and light commercial heating and cooling systems. It provides touchscreen temperature controls, customizable schedules, remote access, humidity management, ventilation settings, and equipment status information.

The VisionPRO 8000 Smart thermostat can connect to a wireless network and be registered with Total Connect Comfort. Once connected and registered, the thermostat can be monitored and controlled remotely through a compatible computer, tablet, or smartphone using the Total Connect Comfort service.

The thermostat also provides access to indoor temperature and humidity information, outdoor weather information through supported connections, heating and cooling schedules, system status, and maintenance reminders.

The TH8321WF1001 supports several operating modes, including Heat, Cool, Off, Auto, and Emergency Heat on compatible systems. Fan operation can be configured for automatic, continuous, intermittent, or scheduled operation.

For residential use, the thermostat supports four daily program periods: Wake, Leave, Return, and Sleep. For light commercial applications, it offers occupied and unoccupied schedules, holiday programming, and temporary occupancy overrides.

Additional functions include Adaptive Intelligent Recovery, vacation scheduling, humidity control, window frost protection, ventilation management, touchscreen locking, and compressor protection.
