WIRELESS INSTALLATION & INTEGRATION REFERENCE GUIDE FOR TB7200/TB7300/TB7600 SERIES THERMOSTATS

SITE SURVEY OVERVIEW

If available, it is best to have a floor plan layout showing the location of all the proposed thermostats to be installed (Fig. 6).

If possible, perform the survey during occupied hours when other electronic devices such as (computers, wireless laptop, cell
phones, PDA's, wireless telephones, microwave ovens, light ballasts, etc.) would be in use as to generate as much interference
as possible. Some of these devices can generate interference up to 20 feet (6.8 meters) away during normal operation. Even with
possible sources of signal interference, the presence of these wireless devices will most probably not result in any network
performance degradation.
It is important to understand that the survey values recorded are provided as a worst case scenario of a point to point application.
Once the whole network is deployed with a WEBs-AX controller and wireless communication card and all wireless thermostats
are present and functioning as routers, the ability of the network to efficiently route wireless signals cannot be compared to this
simple survey analysis method (Fig. 7). Thus, it is important to remember that the displayed percent signal ONLY represents the
signal strength from point A to point B. As other devices join the network mesh, the route taken from device A to device B will
most likely change.
A dense cluster of wireless thermostats will allow your network to recover from temporary disturbances more swiftly.
