Cycle analysis
Delta-T over time
Return minus supply temp during ON cycles. Drift downward = efficiency loss or refrigerant issue.
Delta-T
16°F min
22°F max
SHR trending
Sensible heat ratio over time. Lower = more dehumidification. Trending up = system struggling with latent load.
SHR
Humidity & mold risk
Attic coupling — RH gap over time
Attic RH minus average conditioned space RH. Above 10% = coupling failure (H004).
Dew point risk hours by sensor
Hours per day each sensor spent above 60°F dew point threshold.
Runtime vs outdoor temperature
Each dot = one hour. Correlation shows whether runtime is load-driven or equipment-driven.
