THX9321 PRESTIGE 2.0 AND THX9421 PRESTIGE
The thermostat will call for the fan and lockout all other
equipment until the dry contact device senses air flow
again or the feature is unconfigured at the thermostat.
Custom Alert
Allows the dealer to enter a custom alert to be displayed
when a dry contact device is activated. For example, a float
switch can detect when your sump pump is not working.
Get Connected Alert
This alert will inform homeowners about the RedLINK
Internet Gateway so they can control their thermostat
using the My Total Connect Comfort app from their phone,
tablet, or PC. The alert only appears if the thermostat has
been installed without a RedLINK internet gateway
enrolled for 14 consecutive days. The alert can be snoozed
or permanently dismissed by the homeowner.
