Does a Clinic Waiting Room Diffuser Need a Key-Lock and Auto-Stop?

Treat this as a public-space design question, because that is what it is. A device standing in a household answers to the people who live there, who know the settings and generally have no reason to change them. A device standing in a clinic reception answers to a room that fills and empties all day with people who have never seen it before - patients, the person accompanying them, children who are bored and curious, and front-desk staff who rotate across shifts and may not all have been told what the "correct" setting is. Anything within reach in that room, by default, can be touched, and a diffuser with an exposed intensity dial or an unlocked schedule is no exception. A key-lock removes that risk directly: once a practice manager has calibrated the intensity and schedule after the first week, as recommended throughout this cluster, the key-lock keeps that agreed setting in place until someone with the key deliberately changes it, rather than leaving it to drift because a curious child or an unfamiliar visitor pressed a button. It is a small, low-cost feature that matters precisely because a clinic reception is public in a way a living room is not. Auto-stop answers a related but separate concern: what happens when nobody is specifically watching the machine, which describes most of a working day in a busy reception. Rather than depending on a staff member remembering to switch the unit off at the end of a run, or during a fire drill, or when the schedule genuinely should change, auto-stop is a built-in default behaviour the machine falls back to on its own. Combined with the SOSA Vaayu's 1h/4h/8h/24h app timers, the practical result is a machine that starts, runs and stops on a schedule nobody has to remember, and cannot be nudged off that schedule by someone passing it in the waiting area. This sits alongside the machine's other public-space design choices: it is freestanding, wall-mounted or HVAC-mounted, so it can be placed genuinely out of reach above eye level rather than on a low table; it is waterless, so there is no water reservoir at hand height either; and it runs under 38dB, so it does not draw attention to itself as an object worth investigating. None of this replaces the clinic's own judgement about where the machine physically sits, or the reminder that treatment and procedure rooms stay unscented regardless of any of these features. Ask for a clinic scenting plan and we will confirm the settings worth locking in for your reception.
