Error logging
Errors will be logged for a stand-alone system or for a complete cascade system (based on the cascade settings).
The display will monitor the error number(s) it receives from the water heater(s): new errors 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.
Note: the error log is a completely different error logging mechanism than the one used by the burner control
itself. Therefore, the error log is different from the (internal) error history of the burner control.
The error log can be seen from the error log menu, which is located in the Information menu. In the Error log
menu the following options can be selected:
(Sub) Menu item
Error Log
Filter Error Type
Filter Boiler ID (Cascade System
Clear Error Log
only)
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 following table describes what is displayed inside the Error log:

Service reminder
The Service reminder will remind the owner/user of the appliance to service the appliance every 2000 burn
hours. When service is not done within this time, a message will be shown on the screen: "Service is required!",
alternating with the normal status display.
NOTE: with the message "Service is required" the boiler keeps running , but maintenance must be done before
resetting this message.
When the Service reminder has become active, the time it takes before service is actually done is being logged (in
hours). This time is called the Service Overdue Time.
The Service reminder can be reset by the installer who services the appliance.
Service status information can be viewed at: Menu/ Information/ Service:

Shows the number of burn hours since the last service moment.
