How it works:
Asymmetric control: ramp-up uses the hottest intake sensor; ramp-down uses the average of both. Four-zone curve: below ramp-min → off; ramp-min → ramp-start: wind-down (0–15%); ramp-start → ramp-mid: gentle (15–40%); ramp-mid → ramp-max: stronger (40–100%); above ramp-max = full power. Exhaust override: if either exhaust sensor exceeds max-exhaust → instant max fans. Slew rate caps how much frequency moves per 60s cycle for smooth transitions.
