Gree error code E7
What it means
Mode conflict between indoor and outdoor units.
Possible causes
Indoor units connected to a common outdoor set to different modes Configuration mismatch in multi-room system Control logic detecting incompatible operating demands
Suggested fix
Ensure all connected indoor units are set to compatible modes (for example all cooling or all heating) and verify configuration settings; adjust any incorrect system settings.
Safety first. Isolate the power supply before inspecting any unit. Refrigerant-circuit
and electrical repairs must be carried out by a qualified, registered technician.
