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. When an alarm is present,
a hammer striking a bell appears at the top of the screen. The word “Alarm” appears beside the ham-
mer and bell. The second quadrant down displays a rotating fan when 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 snow-
flake is shown next to the word “Cooling.” If the control is calling for heating, 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 calling for dehumidification, a
shrinking water drop is shown next to the word “Dehumidification”.

4.4.1 Active Alarms
This screen displays any active alarm. The alarms are numbered, #1 being the most recent. The type
of alarm (Urgent or Warning) is also displayed. If there are no active alarms, then “NO ALARMS
PRESENT” will be displayed.
4.4.2 Alarm History Log
A history of the sixty (60) most recent alarms is kept in nonvolatile memory along with the type of
alarm, the alarm name, and the date and time of its occurrence. 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.
NOTE
The display can also be set to display the temperature and humidity setpoints.
