Be sure all controllers / controllers communicating to any single VWG are
using the same PAN ID and Channel as the VWG wireless communication 
card found & set in the property sheet. 
 
Room Temperature, Outdoor Temperature and Room Humidity need to
have their Boolean override counterpart object set to “Override” first if the 
present value needs to be written over from the network. Ex To set a 
network present value on the numeric “{Room Temperature” numeric 
object, the “Room Temperature Override” Boolean object needs to be set 
from Normal to Override. The controller local present value will then be 
derived from the wireless network instead of the present value at the 
controller. 
For VT72xx, VT73xx & VTR73xx, the currently selected Sequence of
Operation Enumeration limits the System Mode usable Enumeration index. 
A change in the Sequence Of Operation Enum will set the active system 
mode and also restrict the usable range that a local controller can accept. 
For VT73xx & VTR73xx, Fan Mode Enumerations. Controllers will not
accept all possible index values. VT73xx & VTR73xx fan mode input is 
dependent on local Fan Configuration parameter. Fan actual current value 
is read at Fan Status object. 
 
Each controller connected to a wireless network reports to the VWG with an
automatic heartbeat for the local online-offline sanity. Please refer to the 
health status “Last Ok Time” value for the total amount of time a single 
controller has not updated its mandatory 3 minutes heartbeat update to the 
VWG.
