Figure 9: Create UCM's Dialog
Wireless Receiver Summary Using Tracer Summit
This option only shows up after the wireless receiver has been setup as described above. This option will show the summary of the
information that the receiver is receiving, including zone sensor number (the serial number), TR Time Sec. (Time since the last
transmission was received in seconds) and RSSI (Receiver Signal Strength Indication). TR Time should not exceed 420 and RSSI
should be between 30 and 255. If TR exceeds 1440, the 24-minute timer has expired and the sensor will show a failure.
1. From the Main Menu, select the Setup Pull Down Menu
2.Highlight the Unit Controllers option and select the VariTrane UCM II/III/IV... Editor
3.Select any UCM that is connected to the receiver and press the "OK" button
4.In the UCM II/III/IV... Editor, open the wireless folder
5.Change the Wireless Receiver Name from Not Assigned to the correct name of the receiver and wait approximately 15 seconds.
The receiver summary will include all sensors from which the receiver is receiving information and should look like the following:

Notes:
1
Average will use the sensed temperature in the temperature averaging calculation. If this is the only sensor the average will
be the sensed temperature.
2
Backup means the UCM will use this temperature only if the primary sensor assigned to the UCM has stopped communicating.
3
Set point vote determines the weighting of the set point vote. The range is 0-9. This number represents the number of votes the
sensor gets when the set points are averaged. If "0" is selected the sensor gets no vote. This is used to disable the thumbwheel.
