Senville ductless-mini-split — Senville ductless mini-split systems across the Aura, Leto, and earlier series documented in Senville support Error Codes Directory

Senville codes: the same characters mean different things by series

Senville publishes different code tables for its Aura, Leto, and earlier series, and the same two characters can describe unrelated conditions between them. The series therefore has to be established before the code is looked up, and the model prefix on the data plate is what establishes it. Applies to: Senville ductless mini-split systems across the Aura, Leto, and earlier series documented in Senville support Senville systems are identified by model prefix rather than by the name printed on the front panel, and the same series name has covered more than one generation. The support document that matches your exact model number is the reference, and a chart labelled only with the brand is not. Owner-safe checks: Photograph the data plates on the indoor and outdoor units and read the full model numbers from the images. | Photograph the displayed code before interrupting power for any reason. | Note whether the system fails at startup or after a period of running, since that alone separates two groups of conditions. Qualified technician: Testing the interconnecting cable, sensing elements, and boards requires casings that carry mains voltage to be opened, which is qualified work. | Conditions reached after a period of operation involve the refrigerant circuit on this equipment, and that is certified activity rather than an owner check.
