CODE 7H-01
Severity: Critical
Difficulty: Intermediate
Water Flow Rate Error Fix
Error 7H-01 triggers when the primary vortex flow sensor detects a water flow rate below the minimum operational threshold (typically < 10-12 L/min depending on unit capacity) during pump operation, or when electrical signal feedback from the vortex sensor fails to register on the main control board, shutting down the compressor to prevent heat exchanger freezing or thermal runaway.
