What does Coreco noP mean?
On the Coreco controller (Dixell XW30/XW60/XW70), noP is a display message: in programming it means no parameter is present in the Pr1 user menu, and on the display (or in dP2/dP3/dP4) it means the selected probe is not enabled.
Symptoms
- Display shows noP in the Pr1 menu (no user parameters)
- noP when trying to view a probe that is not enabled
Common causes
- No parameters moved to the Pr1 user level
- The selected probe (P2/P3/P4) is not enabled/fitted

Diagnostic steps
Understand the message
noP is informational, not a fault: either Pr1 has no parameters, or the probe you tried to display is not enabled.
Enable the probe or use the hidden menu
To read a probe, enable it in the configuration; to see all parameters, use the Pr2 hidden menu.
When to call a professional
noP is normally an informational/configuration message and does not by itself require service. Involve a technician only if a probe that should be enabled will not report.
