[Ramp Control] Range 4 ceiling at 190 after PID update; stabilization window need increase & future dual-range PID needed

[prathameshnium]

PID values for the temperature controller were recently updated:

Parameter	Value
P	0.5
I	4
D	0

---

Issues Observed

1. Range 4 does not exceed 190
After the PID update, Range 4 appears to be capped and cannot go above 190, requiring a transition to Range 5 in all the module.

2. Range 5 stabilization is too fast
Range 5 operates faster than desired. The current stabilization window of 0.1 K is insufficient , it needs to be increased to 5 K or near by value to allow proper stabilization.

---

Immediate Changes Required

• Increase stabilization window from 0.1 K → 5 K for Range 5.
• Investigate why Range 4 is not exceeding 190 post-PID update.

---

Future Work

• Add support for two separate PID configurations within a range, split by a threshold:
  • Below 100 → PID set A
  • Above 100 → PID set B
