Alarms
Set alarms to alert you to abnormal temperatures or humidity levels and the number of hours the
components have been in operation.
See “Respond to Alarms” on page 52 for information on how to correct these conditions.
Alarms will also alert you to malfunctions; however, malfunction alarms are not
user-definable.
Note: Preset alarm threshold default values are applicable for most precision air conditioning
applications.
Temperature alarms
Path: Main > Setup > System # > Alarms > Temp Thrshlds
Temperature Thresholds. Set the low- and high-temperature alarms for the air at each of the
following locations. When the air temperature at the sensor is outside the range defined by the
thresholds, an alarm will occur.
Humidity alarms
Path: Main > Setup > System # > Alarms > Humidity Thresholds
Humidity Thresholds. Set the low and high humidity alarms for the air at each of the following
locations. When the relative humidity of the air at the sensor is outside the range defined by the
thresholds, an alarm will occur.
Maintenance intervals
Path: Main > Setup > System # > Alarms > Maint Intervals
The display interface records the number of hours each of the eight components in each Module has
operated. Set the maintenance interval for each type of component in the Modules of your System. Every
time the run hours for a component in a Module elapse this number of hours, an alarm will occur. Move
the selector arrow next to the component name (top line of the screen) and press the
ENTER key to scroll
through each of the eight components.
Sply (Supply) Temperature thresholds for the conditioned supply air.

(either the return or the remote sensors, depending on your settings).
Sply Humidity thresholds for the air blown into the room (supply air).
Rtrn Humidity thresholds for the air drawn out of the room (return air).
