Installation instructions for the Johnson Controls LN Series LN-VSTAT-1 and LN-PSTAT-1 wall sensors, which connect to the SMRT ports of LN Series controllers. The SMRT ports supply power and serial communications to the sensor, which provides precision local temperature sensing, allows occupants to adjust the local setpoint, and displays occupancy status, local space temperature, and outside air temperature.

Terminal Wiring Details
Wiring the LN-VSTAT and LN-PSTAT Sensors
to a Controller
The LN-VSTAT and LN-PSTAT sensors use a serial
communication protocol and are designed to connect to
the serial inputs labelled SMRT+ and SMRT- on the
LN-VAVLF and LN-VVTLF controller.
Note: The LN-VAVCF controller does not support the
LN-VSTAT and LN-PSTAT sensors.
To wire a wall mounted LN-VAV/VVT controller:
1. Remove the faceplate.
2. Use a screwdriver to press down the tabs located
on the bottom of the sensor to remove the cover.

1. Use the taps on the bottom of the sensor to remove

2. Connect the SMRT+ and SMRT- output terminals
of the LN-VSTAT sensors to two wires that
terminate in the 1/8 in. audio plug (Figure 7).

Using the LN-VSTAT as a Portable Device
You can use the LN-VSTAT sensors as a portable
device to perform VAV balancing. If an LN-Sensor is
already connected to the VAV that you intend to
balance, directly connect the LN-VSTAT to the
communication jack within the LN Series Sensor. Figure 7: SMRT+ and SMRT- Output Terminals
