LN Series LN-VSTAT and LN-PSTAT Sensors
Installation Instructions
LN-VSTAT-1, LN-PSTAT-1
Applications
The LN Series LN-VSTAT and LN-PSTAT sensors are
specifically designed to connect to the SMRT ports of
the Johnson Controls' LN Series controllers. The
LN-VSTAT-1 works with the LN-VAVFLFS-1 and
LN-VVTLFS-1 controllers. The LN PSTAT-1 works with
the LN-PFCU-1 and LN-PFCUA-1 controllers. The
SMRT ports supply power and serial communications
to the LN-VSTAT and LN-PSTAT sensors. The device
provides precision local temperature sensing and it
allows occupants to adjust the local setpoint and view
the occupancy status, local space temperature, and
outside air temperature.
North American Emissions Compliance
United States
Compliance Statement (Part 15.19)
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:

To comply with FCC RF exposure requirements for mobile
transmitting devices, this transmitter should only be used
or installed at locations where there is at least 20cm
separation distance between the antenna and all persons.
Canada
Industry Canada Statement
This Class (A) digital apparatus meets all the requirements
of the Canadian Interference-Causing Equipment
Regulations.
Le terme «IC» précédant le numéro de d'accréditation/
inscription signifie simplement que le produit est conforme
aux spécifications techniques d'Industry Canada.
Installation
For proper installation and subsequent operation of the
LN-VSTAT and LN-PSTAT sensors, follow these
recommendations:
Allow for proper clearance of device casing and
wiring terminals for easy access, hardware
configuration, and maintenance.
The sensor is designed to operate under the
following conditions:
Ensure proper ventilation of devices and avoid
areas where corroding, deteriorating, or explosive
vapors, fumes, or gasses may be present.
IMPORTANT: Work in a static-free area. Discharge
static electricity by touching a known, securely
grounded object. Do not handle the controller without
proper protection against static discharge. Use a wrist
strap when handling the controller. Secure the wrist
strap clamp to earth ground.
