* If an EIM is used, or ISU 222 “Economizer fault FDD” is
set to “no” then the A-L/A is used for economizer control.
If ISU 222 “Economizer fault FDD” is set to “yes” then the
U1 contacts are used for economizer control.
Time of Day (TOD)
The thermostat can be set up for a Time of Day output in
the installer setup. This output is commonly used to control
lighting panels, turning them on for occupied periods and
off for unoccupied periods. Table 6 explains how the TOD
feature works with various thermostat modes.
* If an EIM is used, or ISU 222 “Economizer fault FDD” is
set to “no” then the A-L/A is used for TOD control. If ISU
222 “Economizer fault FDD” is set to “yes” then the U1
contacts are used for TOD control.
The Economizer Module and Time of Day output connect
to the A-L/A terminal at the thermostat or EIM and are set
up at ISU 222.

Pre-Occupancy Purge
The thermostat can be set up for Pre-Occupancy Purge in
the installer setup (ISU 401). When setup for Pre-
Occupancy Purge, the thermostat runs the fan 1 to 3 hours
before each occupied period to provide a comfortable
workplace upon arrival. Options are Off and 1 to 3 hours.
