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.

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.

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.

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 

E

 key to scroll 

through each of the eight components. 

Temperature thresholds for the conditioned supply air.

Thresholds for the air at the sensors that are controlling the room temperature 
(either the return or the remote sensors, depending on your settings).

Humidity thresholds for the air blown into the room (supply air).

Humidity thresholds for the air drawn out of the room (return air).
