What it means
On a multi-zone system, one room calling for heating while another calls for cooling can stop one head and show --/---- or a conflict status. That is a control conflict, not a failed part.
Urgency
Not an error
This is a normal status indication, not an error, unless comfort is poor, water is present, or the indication never clears.
Likely causes
Homeowner fix
Set all connected indoor heads to the same mode, then wait several minutes. Expected result: the conflict clears and zones resume in one shared mode.
When to call a pro
No technician is needed for this status by itself. Call for service only if comfort is poor, water is present, or the indication never clears after conditions change.
Repair vs replace
This is a normal operating status, not a repair-or-replace decision.
