Case study
Segment LCD for a Floor Heating Thermostat
Room temperature, setpoint and schedule state on a wall thermostat expected to run for years.
The requirement
A wall thermostat is a long-life product: it stays installed for a decade, is looked at from a standing position and must be legible in a dim hallway.
What we supplied
- Segment layout with a large room-temperature field and a secondary setpoint field
- Schedule, heating and holiday indicators
- Transflective structure with a low-current backlight
- Outline matched to the wall plate, with the buttons around the display
Design note
For wall-mounted products the viewing direction is decided by the mounting height, not by the designer. Fixing it at drawing review avoids a polarizer change later.
