Trane's VariTrac

[scepter]

I have a VariTrac system that according to the paperwork will allow me to use one wall sensor and operate up to three VariTrac boxes. In my application I want to operate just two boxes. When I connect up the sensor wires #1, #2, #3 on both UCM’s (Ver.4.2) I see lower than normal temperature and thumbwheel set points at the CCP.
My question is do I need to install some resistors? If so where and what size? Or is there a configuration in Eware that I need to change?
I just ran into this today right before it was time to go home so I did not get to investigate it much. I thought I would get some of your “inputs” to this over the weekend.

Thanks in advance.

you need to make one a master and one a slave by cutting two resistors on the slave UCM, I am thinking 5 and 6 but just got back from playing golf http://smileys.smileycentral.com/cat/10/10_7_3.gif if you read the IOM for a VAV box it will clarify what you are to do!! Also calibrate the zone sensor after, you will be off by 1 to 3 degrees.

I will check that manual before I head back out.
