Sensors are included or removed from the group by entering the two-digit channel number. After a sensor is added or removed, the list

will be re-sorted so it does not matter in which order the sensors are added or removed. The default is to include all sensors of the

specified type.

When the first digit of a sensor number is entered (a leading zero must be entered if the number is less than ten), the display will prompt

to Add or Remove a sensor from the group.

When the second digit is entered, the sensor will be added or removed from the control group, provided the sensor is of the proper

type, NO

in this example. If the sensor is of the wrong type, or an invalid sensor channel number is entered, the request will not be

completed.
