This screen displays the equipment configuration.
SOFTWARE UPDATES
When the initial power-up sequence is complete and the thermostat is
connected to Wi-Fi, if a software update is available, an OTA software
update begins. This occurs approximately 5 minutes after the thermostat
is connected to Wi-Fi. See Figure 30.
When the OTA update is complete, if a communicating thermostat has
not
identified the indoor or outdoor controls, you
MUST
restore the ther-
mostat defaults to complete the system configuration properly. See the
System Configuration section for details.

NOTICE
During heating, the modulating furnace airflow is controlled by the igni-
tion control, not the thermostat.
NOTICE
