Case study
Display for a Fresh Air System Controller
Temperature, fan speed and filter status on a wall-mounted controller that is read from across the room.
The requirement
The controller is mounted on a wall and read from a distance, so character height mattered more than the number of parameters shown.
What we supplied
- Segment layout with an oversized temperature field and secondary fields for fan speed and timer
- Filter-life indicator and mode icons
- Transflective structure: readable in daylight, backlit at night
- Connector and outline matched to the wall plate
Result
The display fits the existing wall plate without changing the moulding, which kept the tooling cost of the controller unchanged.
