Application  

A ZFR1811 Wireless Field Bus Router is used with 
Field Equipment Advanced Application Controllers 
(FACs), Field Equipment Controllers (FECs), Input/
Output Modules (IOMs), and Variable Air Volume 
Modular Assembly (VMA) Series field controllers.

The ZFR1811 Router provides a wireless interface 
between:

•

a field controller and the supervisory controller (by 
means of a ZFR1810 Coordinator)

•

a field controller and associated WRZ Series 
Wireless Room Sensors

Additionally, the ZFR1811 Wireless Field Bus Router 
can be used as a repeater in WRZ-7860-0 One-to-One 
Wireless Room Temperature Sensing System. For 
more information, refer to the 

WRZ Series One-to-One 

Wireless Room Sensing System Technical Bulletin 
(LIT-12011641)

. 

Up to nine WRZ Series Sensors can be associated 
with a single field controller. In multi-sensor 
applications, the ZFR1811 Router passes all the 
sensor data to an FAC, FEC, IOM, or VMA controller, 
which can be configured to either average the sensors’ 
input or select the highest or lowest sensed condition 
for control of the target zone.

A ZFR1811 Router is powered directly from the 
connected field controller’s 15 VDC output. 

The Router can also be powered by the power supply 
in the Repeater Accessory Kit to serve as a 
stand-alone repeater, extending the range of the 
communications within the wireless mesh network.

Refer to the 

ZFR1800 Series Wireless Field Bus 

System Technical Bulletin (LIT-12011295)

 or the 

ZFR1800 Series Wireless Field Bus System Quick 
Reference Guide (LIT-12011630)

 for information on 

commissioning and configuring a ZFR1800 Series 
Wireless Field Bus System for operation.

Use the ZFR1811 Wireless Field Bus Router

only to 

provide an input to equipment under normal 
operating conditions. Where failure or malfunction of 
the ZFR1811 Router could lead to personal injury or 
property damage to the controlled equipment or 
other property, additional precautions must be 
designed into the control system. Incorporate and 
maintain other devices, such as supervisory or 
alarm systems or safety or limit controls, intended to 
warn of or protect against failure or malfunction of 
the ZFR1811 Router.

IMPORTANT:

The ZFR1800 Series Wireless Field 

Bus System is not designed or intended for use in 
mission-critical or life/safety applications.
