MENU J – FACTORY SETTINGS (factory level) continued
Temp Sensors Used: Select how many rack sensors are installed. If 1 or more
sensors are installed, the rack mode is enabled and the settings below will appear.
Range of selection is 0 (default) to 32. Note: An external rack sensor module is
required when more than 1 sensor is selected. However, on the IRDX and IRCW
model, up to three rack sensors may be installed without needing an external rack
sensor module.
Groups Used: (only shown when external module is installed). This is the total
number of groups that the sensors will be arranged in. Range of adjustment is:
None (default setting) to 16. When groups are not used, all sensors are effectively
in the same group.
Exclude T Band:
amount of deviation from the average rack temperature. If a sensor deviates more
that this setting, it will be excluded from control and determining the average
temperature. Once it comes back within the exclude T band for at least 60
seconds, it will return to normal function. Range of adjustment is
with a default setting of
Use Highest: The rack temperature can be determined by using the Highest or the
Average temperature of sensors or groups of sensors.
Avg: (Shown only when using groups are used and using average setting). Allows
you to choose how the average temperature of groups is made up. Range of
selection is: All Groups (default), Highest 2 Groups to Highest 15 groups.
Refresh Rate: This is how often the highest sensors and groups are determined.
Range of adjustment is 5m, 15m, 30m, 45m, 1Hr, to 24Hrs with a default of 5m.
Offset Setpoint: (Default is No).
offset when the fan runs at 100%. The set point will be offset at a rate of
minute. The maximum offset is limited by the set point's lower limit of adjustment.
