Fan Operation Settings

The Honeywell T4 Pro Programmable Thermostat provides control over your HVAC system’s fan operation, allowing you to optimize air circulation and improve indoor air quality. The fan settings allow you to choose how the fan operates independently of the heating or cooling cycles.

• On⁚ Selecting On mode keeps the fan running continuously, regardless of whether the heating or cooling system is active. This setting is ideal for improved air circulation and distribution, particularly beneficial for homes with multiple levels or open floor plans.
• Circulate⁚ The Circulate mode allows you to run the fan for a predetermined period, often 30 minutes, regardless of the heating or cooling system’s status. This setting is useful for circulating air and removing stale air, especially during periods of inactivity or when the HVAC system is off.

To access and adjust the fan operation settings, use the Fan button on your T4 Pro Thermostat. Selecting the appropriate fan mode based on your preferences and needs will enhance your home’s comfort and air quality.
