SUMMARY
The discussion clarifies the concept of proportional band in temperature control systems, specifically in relation to a fan regulator with a temperature sensor and potentiometer. The proportional band, adjustable between 1-8°C, determines the allowable temperature drift from the setpoint before the fan activates or deactivates. For instance, with a setpoint of 30°C and a proportional band of 5°C, the fan speed varies from 0% at 30°C to 100% at 25°C. Additionally, the discussion distinguishes between proportional band and deadband, highlighting that deadband control operates within a fixed range to maintain temperature stability.
