What Flashing humidity with (!) below the low limit
actually means.
The low humidity alarm flashes the humidity number with the (!) symbol when relative humidity drops below setting 4 and clears when it rises back above it. A cooling unit dries the air as it runs, so a unit running long hours, a very dry season or a humidifier that has stopped can bring it on.

What to do when Flashing humidity with (!) below the low limit shows on the wine cellar cooling unitKind of codeHumidity
The unit or its hygrometer reads the cellar's air as too dry for the corks or too damp for the labels and the walls. Cooling pulls water out of the air, so a unit that runs long in a leaky room tends to dry it out, while a gap in the vapor barrier, damp ground or a clogged drain can push it the other way. A humidifier or humidity kit, where one is fitted, is checked along with the door seal and the room before a sensor is blamed.

Shows up asWine Cellar Humidity Too Low

Each step comes from Wine Guardian's own guidance for Flashing humidity with (!) below the low limit on its wine cellar cooling units. Follow it to the end: the last card says whether this is a visit.
If a Wine Guardian humidifier is connected, check that it has water and power and that its setpoint is where you want it.
Check whether the unit runs almost without stopping; long run times dry the room.
If the room stays dry with the humidifier working, book a visit to look at the fan settings and the room.

What not to do
