Viconics Electronics Inc. VWG40 User Manual

(Issue Date June 9, 2008 – 028-6013 E06) 

 
The VWG-40 and related wireless thermostats are targeted to retrofit applications where 
the addition of communicating field bus wiring within the building space is prohibitive. The 
Gateway and Communicating Thermostats with wireless field bus encourages the use of 
existing wiring utilized by existing electronic thermostat type controls.  
 
The VWG-40-XX-1000 when utilized in conjunction with the VT7xxxXxxxxW series wireless 
thermostats will offer the integrator simple BACnet IP or BACnet MS/TP objects to integrate over standard 
building automation systems using familiar integration toolsets. 
 
A maximum of 30 wireless thermostats can be wirelessly attached to a single VWG
