01
Separate controller, actuator, plant, and sensor blocks for clarity.
02
Sum junction with visual + and - signs for error computation.
03
Explicit sensor block feeding both the error sum and output signal.
Reusable for any closed-loop temperature or climate control system (e.g., HVAC, incubators) by relabeling blocks and signals.
