Error logging.
Error logging is available. This functionality is linked to the Real-Time Clock functionality.
Errors will be logged for a stand-alone system or for a complete cascade system (based on the cascade settings).
The PB display will monitor the error codes it receives from the water heater(s) and if an error code is a new error
code the error will be stored in the error log. An error will be logged with a (real-time clock) time stamp (date and
time) when the error was detected and a water heater ID of the water heater on which the error was detected.
The error log can be viewed from the error log menu, which is located in the information menu.

When no filtering option is selected (Disabled) the error log will
show all errors for that category. So, if both filters are disabled,
the error log will show all the errors in the log.
The error log screen will show on the first line: Water heater ID for which water heater the error was detected
(cascade system only), Error Code, (internal) Error Number, Error Type (Lockout/Blocking).
The second line will show the Error Description.
The bottom line will show the Time Stamp (date and time) when the error was detected (in the format as configured
in the Date Time Settings menu), and also the selected error index from the total number of errors in the (filtered)
error log. Only Time Stamp, Code and Description is displayed.
Example, see picture above.
A014 = Error code.
(14) = Error Number (tracking number, 1-15 errors are stored maximum).
Lockout = Error type.
Air Switch Not Closed = Error description.
Wed 04-11-2018 14:50 = Time stamp when the error occurred.
Service reminder
The Service reminder will remind the owner/user of the appliance to service the appliance at a specified "Service
Interval", factory set on 2000 burn hours. When service is not done within this time, a service reminder will be
shown on the screen: "Service is required!", alternating with the normal status display.
NOTE: with the message "Service is required" the water heater keeps running, but maintenance must be done
before resetting this message.

ERVICE OVERDUE LOGGING
Menu/ Information/ Service/ Service history.
When the Service reminder has become active, the time (in hours) it takes before service is actually done is being
logged. This time is called the Service Overdue Time.
A maximum of 15 service moments can be logged by the system. When the log is full it will overwrite the oldest log
entry. Each time the Service reminder is reset, a new service moment is logged (counted) and the Service Overdue
counter will be stored in the log/history.
