Firmware Update

FIRMWARE UPDATE BUTTON
1. Firmware Update (Off) – No automatic firmware
updates (highly recommend leaving ON)
2. If the status is changed from Off to Auto, it will trigger
an immediate check and update for the firmware
update. This can take up to 1 hour to complete
depending on the user's internet speed, signal
strength, internet traffic, etc.
3. Changing from Auto to Off during a download will
NOT stop the current download if it is already in
process.
4. Firmware Update (Auto) – (Default state). If
enabled, the thermostat checks for firmware update
a few minutes after commissioning and then every
24 hours in early morning hours.
5. Once a download is completed, the thermostat stops
all activity for up to 3 seconds, restarts for 5 seconds,
then continues with normal operation. All prior
system and user settings are retained (Equipment,
programs, Wi-Fi settings, etc.). Note a variation in
indoor temperature may be observed after restart.
This is normal operation of the thermostat while the
temperature sensor algorithms adjust after a restart
of the system.
