Product Information

The Honeywell Vision PRO IAQ (YTH9421C1002) is a universal touchscreen programmable thermostat. Advanced Honeywell thermostats remove air pollutants by exchanging the stale air in your home with fresh and filtered air from the outdoors. This Vision PRO IAQ touchscreen programmable Honeywell thermostat features duel-fuel electronic control of up to 4 heat/2 cool stages for Vac heating and cooling systems.

The Honeywell VisionPRO thermostat automatically raises humidity levels throughout all rooms in your home, moisturizing the air in order to protect hardwood flooring and other woodwork. The Honeywell digital programmable thermostat includes Humidification Control with or without Frost Protection, Dehumidification using Whole House Dehumidifier, Air Conditioning with High or Low speed fan, Advanced Patented Ventilation Control, and Advanced Dual Fuel Heat Pump Control. The Honeywell VisionPro uses just 3 wires to the thermostat instead of needing to run additional thermostat wires.

The Honeywell thermostat touchscreen connects to the Equipment Interface Module or EnviraZONE panel to control temperature, humidification, dehumidification, and ventilation from a single point.
