Saunum Releases Leil Software Update With Better AutoLeil Stability and Fan Control

Saunum has released a new software update for its Leil control system, focused on day-to-day usability rather than a flashy product launch. For owners already using Leil, the headline is straightforward: smoother navigation, more reliable updates, and better in-session control over fan and climate behavior.

Saunum's Leil/AirIQ control panel hardware for temperature, time, and climate controls.

The update also improves the update process itself, which matters more than it sounds. Control software only helps if it is easy to keep current, and Saunum says this release reduces friction in that maintenance cycle while refining lighting and ventilation menus.

Fan Access While Screen Is Locked

The most practical improvement may be fan behavior: users can now run the fan even when the screen is locked. That removes an annoying mid-session step and makes it easier to adjust air circulation without interrupting the flow of a session.

AutoLeil Gets More Stable Session Control

Saunum says the update improves AutoLeil precision and stability, with more consistent humidity behavior based on user settings. AutoLeil is Saunum's automatic water-dosing accessory, designed to feed water to heater stones through the control ecosystem and help maintain a steadier sauna climate.

That same usability trend shows up in smaller accessories and airflow details, including in-sauna fan controls and guidance components that help direct mixed air where bathers feel it most.

How to Install the Update

Saunum says Leil owners can install this release directly from the remote panel. Both the control panel and power board need updates; the order does not matter. Exact steps can vary by installed software version.

This is a practical quality-of-life release. It is not new hardware, but it should reduce interruptions and deliver steadier humidity and airflow behavior once installed. For official product and support resources, visit Saunum and Saunum U.S..
