u/Acceptable_Alarm_164

I have a Trane Precedent RTU with a Baysense 135A wired stat connected via Bacnet Mstp to a Symbio 700 interface. Using the Space Temp Stp Single Stp Method I want it set up where the user has control unless a BAS admin takes over by writing to the BMS setpoint AV:10127. The problem I’m having is the point Analog Input:11161 which is the setpoint from the wired sensor is coming in 2 degrees below where it is actually set. (Ex. set at the stat at 70 deg coming in the BAS at 68.3 deg) I have checked the wiring and it’s good any ideas why Analog Input:11161 does not match the setpoint that is shown on the stat itself?

Thank you for your help.
