GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM OUTSIDE NETWORK TEMPERATURE SENSOR WITH SUN AND WINDSHIELD TNOB SERIES PRODUCT DESCRIPTION The single point outside network temperature transmitter sensor incorporates a precision sensor housed in a protective sun/wind shield. All probes are constructed to provide excellent heat transfer, fast response and are potted to resist moisture penetration. The transmitter provides a BACnet® or Modbus signal for network connection. A compact, weatherproof ABS enclosure with a hinged and gasketed cover is provided for ease of installation. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The outside temperature transmitter should be mounted on an outside North facing wall, under the eaves which will provide protection from direct sunlight. The outside temperature sensor can be mounted directly to the building’s wall face using the provided mounting holes. There is one 0.85” hole for conduit connection. NOTE: This product is factory calibrated and any field adjustment will void the warranty.

BACnet® COMMUNICATION BACnet® is a data communication protocol for building automation and control networks. The sensor communicates on a standard 2-wire RS-485 MS/TP network designed to run at speeds from 9600 to 115200 baud over twisted pair wiring. BACnet® is a registered trademark of ASHRAE. ASHRAE does not endorse, approve or test products for compliance with ASHRAE standards. Compliance of BACnet® listed products to the requirements of ASHRAE Standard 135 is the responsibility of BACnet® International (BI). BTL is a registered trademark of BI. MODBUS COMMUNICATION Modbus is a network protocol for industrial manufacturing environments. The sensor communicates on a standard Modbus network using the RTU (Remote Terminal Unit) transmission mode. The hardware interface is RS-485.
