Finally, fresh water within reach. Durlem Vi Connect, your connected water softener. With the My Durlem app for the Vi Mini–Maxi range, you can: - See whether your softener is in “softening” or “regeneration” mode - Check whether your softener is “online” or “offline” - View the remaining softened water capacity before the next regeneration - See the volume of water treated since the last regeneration - Subscribe to a maintenance contract and access after-sales service - View your softener’s configuration parameters - Activate vacation mode: this mode allows you to shut down the softener for a set period - Check if the softener needs salt thanks to two distinct alarms—one works via a disinfection probe, while the other is based on a “degressive” calculation estimating the remaining salt (the second alarm is available starting from software version 00.00.42). Both can be enabled or disabled by the user. - Receive maintenance reminders via an alarm and schedule a maintenance appointment - Be alerted in case of a water leak in your plumbing system - Request notifications in your smartphone’s notification bar and/or by email for alerts - Contact Durlem to request maintenance or repair service - Record your plumbing installer’s information - Add an additional email address for email notifications (e.g., owner–tenant) - View network signal quality and the name of the network your softener is connected to - Reset the Wi-Fi network linked to the softener
