The system sent a temperature compensation request but the difference in temperature between a pair or thermistors indicates a temperature gradient that exceeds the configured system limits. Temperature compensation is active, but the system conditions may preclude achieving the desired system accuracy. The message includes the thermistor number or numbers, and the recorded temperature or temperatures that caused the warning.
