Adding a Wired Temperature Sensor
The procedure shown below adds a wired Blue temperature sensor, but is applicable to the wired Red and White temperature sensors as well.
The Hysteresis setting helps prevent alarms from being set and reset continually if the environment is at or near the alarm set point by providing an acceptable variance. For example, if HYSTERESIS is set at 1 and the sensor High Alarm Limit is set at +158, the sensor reading must decrease to +157 (+157 minus 1) in order for the temperature alarm to reset to a
When setting numeric values, use the arrow keys to change the value. Use the PREV and NEXT soft keys to move the cursor to the next or previous digit. Press the ENTER key to enter the value.
NOTE: Select the sensor number that matches the input number used by the sensor, or an alarm may result.
Example values are shown, Set all limit values as appropriate for your system.
