WARNING / CRITICAL
Alert thresholds
EDGE + TELEGRAM
The first threshold crossing immediately creates an Edge Gateway alert and a Telegram message. Repeated samples do not create spam; the next message is sent on escalation or recovery.
SCD41 CALIBRATION
CO₂ · ASC and FRC
CHECKING
ASC does not require a weekly button press. The sensor needs exposure to fresh air near 400 ppm for more than three minutes. This panel records that exposure. FRC is a separate forced procedure with a verified reference CO₂ concentration.
