Warnings are generated to enunciate the system is not operating optimally, but the Aquastat is still operating and maintaining
boiler temperature. In the instance where an Outdoor Reset Module is used, the warnings may indicate a reset curve setting
error one or more features is not running optimally, and the Aquastat is reverting to default settings or has stopped running
the Outdoor Reset algorithms. The warnings are cleared when the issue(s) is resolved.
