Control Logic

Watts are adjusted automatically until the target HR is maintained.

HR > Target + 3 bpm → Watt ↓

HR < Target − 3 bpm → Watt ↑

HR ≈ Target ± 3 bpm → no change

• Step size proportional to deviation (larger error = larger step)

• HR responds with 30–90 s delay to watt changes

• Adjustment interval of ≥ 10 s recommended

Heart rate monitor and trainer must be connected. Training data is not saved.
