Upgrade your home’s climate control with the professional-grade Honeywell Home Prestige® IAQ. This is one of the most advanced thermostats on the market, offering more than just temperature control—it’s a complete Indoor Air Quality (IAQ) command center.

Why the Prestige IAQ is different:
Unlike standard thermostats that require a bundle of wires, the Prestige IAQ uses a 2-wire installation to the living space. The heavy lifting is done at the Equipment Interface Module (EIM), allowing for a clean, sleek look on your wall while controlling complex multi-stage systems.

Key Features:
High-Definition Color Touchscreen: A vibrant, easy-to-read display with customizable backlight colors to match your home decor.
RedLINK® Wireless Technology: Works with RedLINK accessories like wireless indoor/outdoor sensors, the Portable Comfort Control, and the RedLINK Internet Gateway (for smartphone control).
Complete Air Quality Control: Manage humidification, dehumidification, and ventilation systems all from one interface.
Self-Programming Interview: The thermostat asks you a series of simple questions (e.g., "What time does the first person wake up?") and programs itself based on your answers.
Smart Scheduling: 7-day programmable with "vacation mode" and "holiday" overrides to maximize energy savings.
Delta T Alerts: Advanced diagnostics that monitor your system’s efficiency and alert you if the equipment isn't performing as expected before a total breakdown occurs.

Technical Specifications:
Compatibility: Up to 4 Heat / 2 Cool Heat Pump systems or 3 Heat / 2 Cool Conventional systems.
Application: Residential or Light Commercial use.
Display: 8.06 sq. inch touchscreen.
Language Options: English, French, or Spanish.
Power: Hardwired (24V).
