"above upper critical" State
This state means a numeric sensor's reading is above the upper critical
threshold as indicated below:
Upper Critical Threshold <= Reading
Note: The symbol <= means smaller than (<) or equal to (=).
States of Managed Actuators
DX sensor packages with dry contact channels allow you to connect
actuators. An actuator has only three states described below. Note that
an actuator is never highlighted in red or yellow regardless of the
actuator states.

unavailable: The communication with the actuator is lost.

On: The actuator has been turned on.

Off: The actuator has been turned off.
States of Unmanaged Sensors or Actuators
All sensors or actuators that are physically connected to the PX while
NOT under management always show the following state:

unmanaged
Note: For firmware versions prior to 3.2.1, unmanaged sensors or
actuators show the state "unavailable."
Unmanaging Environmental Sensors or Actuators
When it is unnecessary to monitor a particular environmental factor, you
can unmanage or release the corresponding environmental sensor so
that the PX device stops retrieving the sensor's reading and/or state.
This procedure also applies if you want to unmanage an actuator.
To release a managed sensor or actuator:
1. Click Peripheral Devices in the left pane.
2. Select the checkbox of the desired sensor or actuator on the
Peripheral Devices page. To release multiple ones, select multiple
checkboxes.
 To select all of those listed on the Peripheral Devices page,
simply select the checkbox in the header row.
