1000 Vent Type
None, ERV/HRV, Passive,
Fresh Air Damper
None: The thermostat does not control ventilation.
ERV/HRV: The thermostat controls an Energy
Recovery Ventilator or Heat Recovery Ventilator
for ventila- tion.
Passive (Fan Only): The thermostat turns on the
fan for ventilation. When set to passive fan, the
thermo- stat does not control a damper or
ventilator. The passive ventilation/passive fan
setting only runs the indoor blower fan. This
setting does not open a damper or run a ventilator.
To use this setting for ventilation, the home would
need to be set-up with a pipe from outdoors into
the return duct that is either permanently open or
has a damper that automatically opens whenever
the blower fan is on.
Note: Some models only offer the passive fan
setting.

Percent On
Time
10% – 100% (30%)
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 dur- ing a 1 hour period until
it reaches a 50% run time (approximately 30
minutes). This ISU is only displayed if ISU 1005 is
set to Percent On Time.
