Controls
Technician
LPs, HPs, oil safety, defrost and temperature control — what they protect, how they're set, and never from memory.
Controls tell the system when to run and when to protect itself. Understand what each protects and set it to manufacturer data — never from memory.
Control vs safety
- Controls operate the system (cut-in, cut-out, differential)
- Safeties protect it (manual reset, oil pressure, HP)
- Sensing location decides what they actually see — see Rotalock & Pressure Path
Field Rules
- 01
"Never set controls from memory. Confirm against manufacturer data."
