Dry Contact Alerts

A Dry Contact device such as a wet switch can be
connected to the S1, S2, S3, or S4 terminals at the
Equipment Interface Module.
When the dry contact device detects a problem, the
thermostat displays an alert on the home screen along with
the dealer information. See Fig. 185 as an example.

THX9321 PRESTIGE 2.0 AND THX9421 PRESTIGE
When the user presses the alert for more info, the
Notification screen is displayed, prompting them to
contact their dealer. See Fig. 186 as an example.
The following dry contact alerts are available.
Full Drain Pan Alert
When the dry contact device detects that the condensate
drain pan is full, the thermostat provides an alert to the
user.
NOTE: If you want the compressor to turn off when the
drain pan is full, wire the system so the dry contact
device turns off the compressor when the drain
pan is full.
Dirty Filter Alert
When the dry contact device detects a dirty air filter
(pressure drop across the filter), the thermostat provides
an alert to the user to replace the filter.
Water Leak Alert
When the dry contact device detects a water leak, the
thermostat provides an alert to the user.
System Shutdown Alert
When the dry contact device detects a critical problem with
the system, the thermostat provides an alert to the user
indicating that the system was shut down.
When the dry contact device detects a problem with the
system (for example, smoke detection), the thermostat will
not call for heating, cooling, fan or IAQ equipment until the
dry contact is deactivated or the feature is unconfigured at
the thermostat.
Service Needed Alert
When the dry contact device detects an issue that requires
service, the thermostat provides an alert to the user.
Fan Failure Alert
The Fan Failure Alert protects the equipment when there is
no airflow. When the dry contact device (for example, sail
switch) detects no air flow for 5 minutes after a call for
forced air heat, cool, or fan, the thermostat provides an
alert to the user indicating that the system was shut down
due to a lack of airflow.
