NOTE: When an S-Bus sensor is connected to an existing
network, it will take 60 minutes for the network to recognize
and auto-configure itself to use the new sensor.
During the 60-minute setup period, no alarms for sensor
failures (except SAT) will be issued and no economizing
function will be available.
