9.4 Wired Remote Sensors

Wired, remote, rack sensors can function as control sensors and, subsequently, provide input individually, at the unit level, or
at the system level for temperature control and teamwork functions.
Each wired-remote rack sensor has two thermistors/probes. In Individual Sensor mode, the higher temperature reading or
the average temperature reading of the two probes can be used. In Unit Sensors mode, some or all of the rack sensor's
temperature readings are considered for higher (maximum) or average calculation. For example, setting three sensors as
control and average for unit mode, averages the three highest temperature readings.
At the system level, using a unit to unit (U2U) network, the same maximum or average calculations can be based on
readings from all of the sensors in all of the units in group (including those in standby) using teamwork. See
Modes on page 63.

3. Touch a specific sensor. The SENSOR PROPERTIES for that sensor open.
NOTE: The sensor number listed corresponds to the DIP switch assignment of the sensor made during installation.
4. Touch Name, and use the keyboard to give the sensor a descriptive name.
NOTE: This is the name displayed on the REMOTE SENSORS panel for non-service users.
5. Refer to the
settings, and touch Save.
The wired-remote sensors for the cooling unit are configured.
9.4.1 Wired Remote Sensor—Set Up Options
Average Rack Temp
Calculated average of temperature readings from the control sensors.
Individual Remote Sensors Mode
When controlling at the sensor level, selects the method of using the readings from the two temperature thermistors
(probes) on the sensor. Options are:
• Maximum: Use the highest temperature reading of the two thermistors.
• Average: Use the average of the readings from the two thermistors.
Max Rack Temp
Highest temperature reading from the unit remote sensors.
