Both None: The thermostat does not control ventilation.
ERV/HRV: The thermostat controls an Energy
Recovery Ventilator or Heat Recovery Ventilator for
ventilation.
Passive (Fan Only): The thermostat turns on the fan
for ventilation.
Fresh Air Damper: The thermostat turns on the fan
and opens a fresh air damper for ventilation.
Both Number of Outputs:
TH8321 Thermostat: U1 terminals
U1 are dry contacts that require power. See "Wiring
IAQ Equipment or a Heat/Cool Stage to the U1
Terminals" beginning on page 86.
Both See "Ventilation Control Methods (ISU 1005)"
beginning on page 67.
Both Tstat Controls Fan: The thermostat turns on the
ventilation equipment and the fan when ventilation
is needed.
Equip Controls Fan: The thermostat turns on the
ventilation equipment when ventilation is needed.
The fan is controlled by the equipment.

Both The thermostat operates ventilation equipment
based on a percentage entered in the installer setup
(ISU 1012). For example, if Percent on Time is set to
50%, the ventilation equipment will run at random
times during a 1 hour period until it reaches a 50%
run time (approximately 30 minutes).
