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 106.
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.
Both No Manual: The user must select heating or
cooling as needed to maintain the desired
indoor temperature.
Automatic: The user has the option to select
Auto for the system setting. In Auto mode, the
thermostat controls heating and cooling
equipment as needed to maintain the desired
indoor temperature.
