Heat Pump Fault
None Commercial 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 81.
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.
