4D) Communication status LED and Troubleshooting
Each thermostat has a communication status service LED for troubleshooting purposes. Monitoring this
LED will determine the network condition for each individual device and will tell you if they are successfully
communicating with their peers on the network.

Wireless communication with VZ72 Zone thermostats active
The long 3000ms status flag is simply enabled by VZ72xx zone thermostats reporting PI demand value to
the VZ76 RTU thermostat. As long as a single VZ72xx zone thermostat is registered at the VZ76xx RTU,
the long 3000ms status flag will be enabled
If the long 3000ms status flag indicating communication with the VZ7xx wireless zones thermostat is
disabled after one minute; the ComLost alarm flag will be displayed at the VZ76xx RTU thermostat.
