Code Text Description Cause Check Procedure Technical Support Notes 7100 Over capacity error. The total indoor unit capacity exceeds the outdoor unit allowable capacity. On a PURY outdoor you are allowed up to 150% of its capacity.
On a PUHY/PUMY outdoor you can have up to 130% of its capacity.
Add up all the capacities of the indoor units and check they don’t exceed the outdoor unit capacity. Also check the capacity dip switches on the indoor and outdoor unit are set correctly.
This fault can be caused when the system is comprised of two outdoor units piped together and power is lost to one of the outdoors.
