Trane ReliaTel - Setpoint Potentiometers

42 RT-SVD03G-EN
ReliaTel Ventilation Module (RTVM)
J11 Output
J11 - 1, 2 provides a 23Vdc output and common for Space Pressure Transducer calibration. This
output is energized once every 60 seconds.
Setpoint Potentiometers
Space Pressure Setpoint (R40) potentiometer provides a space pressure setpoint for Statitrac
Control. The range is -0.20iwc to 0.30iwc. Default is 0.08iwc.
Space Pressure Setpoint Deadband (R42) potentiometer provides a selectable deadband for
the space pressure setpoint control. The range is 0.02iwc to 0.20iwc. Default is 0.04iwc.
For RTVM v3.0 and later, test point "hooks" are included on the module next to each setpoint
potentiometer to allow a more accurate setup. Connect a DC volt meter to the test point and ground
to verify the desired setpoint according to the tables below:
