Field notes
The situation flow collects the thermostat message and safe observations such as whether the home is warming, whether the outdoor unit appears to run, and what air comes from the vents. It offers model-specific references for ecobee, Nest, Honeywell Home, and Daikin One+, while cautioning that linked guides do not authenticate an installation. The cost example uses nameplate kilowatts and the user's electricity rate; the page describes outdoor temperature as context, not a universal lockout selector.
