Turning an HVAC system on/off every time the room temperature changed slightly could cause the system to cycle on and off several times in the span of a few minutes. This would be noisy, uncomfortable, and could affect the health of system.
All thermostats maintain a range of about 1F around the set point. This is called a hysteresis band, or maintenance band. It prevents excessive wear and tear on your HVAC equipment, and Flair follows this industry standard as well.
Flair uses a hysteresis band of 1F above and below a set point. This applies to the home set point, room set points, schedule event set points and Smart Away set points. Flair uses this band to determine when to open/close Smart Vents, adjust your integrated smart thermostat when Flair is controlling the set point, or adjust your mini split/portable/AC unit when Room Sense is enabled.
If you would like to adjust this temperature band, please email support at email@example.com with the subject: "Request Custom Heat/Cool band".
