I will be creating a graphic to allow laboratory technicians to view the temperature (and humidity and one or two other parameters, however, I will just describe temperature) in their room.
The room will have a default room temperature setpoint as well as a default high alarm temperature and default low alarm temperature.
They have the ability to edit and override these three values.
If the setpoint, high alarm, or low alarm values are not equal to the default values, what indication should be used to let them know? A separate indication for each of the values should be displayed.
