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.
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.
