The display can also be set to display the temperature and humidity setpoints.

See 3.7.7 - Set Status Display.

The right half of the screen is divided into four quadrants (top to bottom). In the four quadrants, six different graphic symbols may be displayed depending on the unit status. At the top there will be a moving hammer striking a bell that appears when an alarm is present. The word “Alarm” also appears next to the hammer and bell. The second quadrant down displays a rotating fan as long as the unit is turned on and the fan is running. The words “Unit on” appear next to the fan symbol. The third quadrant may display one of two symbols relating to heating or cooling. If the control is calling for cooling, a growing snowflake is shown next to the word “Cooling.” If the control is calling for heat- ing, three moving heat rays are displayed next to the word “Heating.” In the bottom quadrant, there may be one of two symbols relating to humidification and dehumidification. If the control is calling for humidification, a growing water drop is shown next to the word “Humidification.” If the control is call- ing for dehumidification, a shrinking water drop is shown next to the word “Dehumidification.”

A history of the 60 most recent alarms is kept in nonvolatile memory complete with the type of alarm, the alarm name, and the date and time it occurred. The first alarm in the history is the most recent and the last (up to 60) is the oldest. If the Alarm History is full (60 alarms) and a new alarm occurs, the oldest is lost and the newest is saved in alarm history location 1. The rest are moved down the list by 1. Alarm history on new units may show the results of factory testing.
