RTC Mismatch - all DynaView (CH530) controlled chillers.
Discussion:
- If the main processor halts operation, and there is a difference between the real-time clock ( RTC ) and oscillator, a diagnostic will be annuciated to show a failure.
- The chiller firmware checks the difference between the real time clock ( RTC ) and the microprocessor clock
- If it is off by a certain amount of time, in seconds ( 70 seconds ); then the controls annunciate the RTC Mismatch diagnostic.
Solution:
- This diagnostic suggests that the microprocessor in the DynaView is locking up; which can lead to catastrophic failure.
- Recommendation is to replace the DynaView Controller.
