If using a TH8321R without EIM and your code
requires that the thermostat display an alert when
the economizer is sending a fault code, select
“Yes”. When this is done, the economizer will need
to be wired as shown in Fig. 339 on page 136. If
EIM used, and economizer fault required, this
option is not available. See Fig. 340 on page 136

This ISU is only displayed when ISU 101
Application is Commercial.
Note: When the thermostat is setup for Residential,
the L/A terminal operates as described under
"Heat Pump Fault". The L/A terminal requires no
setup for residential applications.
None: The A-L/A terminal is not used.
Time of Day: The A-L/A terminal is energized
during Occupied periods and when the user
overrides the temperature. The terminal is de-
energized during Unoccupied periods and in
Standby mode.
Economizer: The thermostat controls an
economizer module to provide ventilation during
Occupied periods and free cooling when outdoor
conditions are favorable. The
A-L/A terminal is energized during Occupied
periods and during a call for cooling in
Unoccupied periods. See “Economizer and Time of
Day (TOD) Operation” beginning on page 107.
Notes: The economizer module determines when
outdoor conditions are favorable for free cooling.
Heat Pump Fault: When 24 volts is detected on the
L/A terminal (compressor monitor), the thermostat
displays a message to alert the user when the heat
pump requires service. The L/A terminal sends a
continuous output to a zone panel when the
thermostat is set to Emergency Heat mode. The
zone panel will not turn on the heat pump when a
zone is set to Emergency Heat mode.
Econ. Fault input: Only shown if “Economizer fault
FDD” is set to “yes”. Not adjustable.
