When I connect the VariTrane F-style boxes with the UCM IV controller to the CCP, they do not show up as "F" boxes and I cannot change them to the correct configuration.

Resolution:

Problem:
When I connect the VariTrane F-style boxes with the UCM IV controller to the CCP, they do not show up as "F" boxes and I cannot change them to the correct configuration.

Solution:
The CCP II was developed before the VariTrane F box and therefore cannot show this configuration as an option. The VAV will communicate and control correctly in spite of this.

Problem:
The CFM reading in Rover does not match the CFM reported in Tracer Summit.

Solution:
Again, this issue stems from the design of the CCPII occuring before the invention of the VariTrane F style VAV box. The box will control correctly to the cfm displayed in Rover, but the reading in Tracer Summit will always be off. As a workaround, you can configure the VAV box as generic and adjust the VFC on the Advanced Configuration tab. Use the following table as a guide.

 

 

In addition, verify the air valve drive time and your minimum and maximum airflows.

• Why is the CCPII displaying a different CFM value than Rover shows?
