Trane Voyager Supply Air Reset
I have a Trane voyger unit, 25-50 ton unit that i'm trying to install a supply air reset from a siemens system. I was told all I need a reset board that has a 0-10 VDC input and a 0-1000 ohm output. The 0-1000 ohm's will interrupt the 0-5VDC thats internal to the Trane unit.
Are you saying your output is 0-10 and your input is 0-5? (actually .5 to 4.5). Why don't you split your 10 volts in half with resistors? Is this an Intellipak with a the remote boards? Do you have the first few from model?
I believe your talking about the GBAS board that Trane sells. Call your local Trane and get a price on it(there should be info on exact name and part number in the manual for the Voyager).

Reason: Intellipaks statement

What you need to do is buy a kele part # res-1 for each stpt you want to remotely control ie: SA Press Stpt, SA Cool Stpt, SA Reset Amount, SA Press DB, MWU Stpt, SA Reset Stpt. In this example 6 boards per unit. If they can live with some of this control at the RTU then all you do is adjust the pots on the RTAM board, also any remote Stpts. you use remember to cut the resistor out for the appropriate Stpt.On the RTAM board.
