1. Fix the System, use, and result to obtain
SYSE.1 keeps GreenhouseClimateControl-GH2 as an intended-system designator selected as the project
system-of-interest and distinguishes it from greenhouse GH-2, company GreenHeat-4, and any actual System
identity that may begin later. SYSE.16 identifies the greenhouse,
electrical supply, heating, ventilation, misting, shading, sensors, operator station, weather, and manual fallback
that form the relevant operating surroundings. SYSE.17 identifies operators, crops, maintainers, the equipment
company, and the greenhouse owner as Systems that can bear consequences.
The receiving use is control during three representative conditions: a cold night, a rapid solar rise, and a
failed humidity sensor. SYSE.2 supplies linked use and System concepts. Acceptance requires bounded temperature
and humidity performance, no unsafe actuator command after sensor failure, identified controller and software
configuration, recoverable observations, and supported manual fallback. These are case inputs from greenhouse-
control and electrical-safety Methods. The case takes its thresholds from those specialist results.
