FEATURES
+ Control is integrated into the Model 8140 Ventilator. The Model
8140NC has no integrated control so the ventilator can be hardwired
to the HVAC system and controlled from within the living space.
+ High and low outdoor temperature limit lock-outs while
maintaining ASHRAE Standard 62.2-2010 (Model 8140 only)
+ High and low indoor relative humidity (RH) limits can be set on the
controller (Model 8140 only)
+ Simple plug-in installation
+ Integrated powered damper
+ Removable, washable filter
BENEFITS
+ Delivers the precise amount of outside air needed in today’s
efficiently designed homes
+ Model 8140 optimizes energy savings by locking out ventilation
during hottest/coldest times of the day
+ Improves indoor air quality
+ Robust design handles hot attics up to 140°F
+ Installation labor reduced, requires only a switched outlet and
24 volt wiring to HVAC system
+ Furnace or air handler does not require an ECM motor to meet
efficacy requirement
When properly installed and set, the Aprilaire Model 8140 will
meet the mechanical ventilation requirements of:*
+ ASHRAE 62.2-2010
+ Energy Star Certified Homes, Version 3
+ EPA Indoor airPLUS, Version 1
+ 2012 & 2015 International Residential Code (IRC)
+ 2012 & 2015 International Energy Conservation Code (IECC)
+ California Energy Commission Title 24
* 8140NC compliance is subject to the functionality of the external control. To assure compliance,
use an 8910, 8910W, 8920W, 8620 or 8620W thermostat or 8120X ventilation controller.

SEQUENCE OF OPERATION – “CODE” SETTING
+ The control will open the vent damper with a heating, cooling or fan
call for the set number of minutes during a one-hour cycle period. If the
outdoor temperature is above the high temperature ventilation limit,
ventilation will not occur with a cool or fan call, but if it is below the low
temperature ventilation limit it will occur with a heat call.
+ If the HVAC equipment does not turn on enough to meet the ventilation
time within the hour, the control will open the vent damper and turn on
the HVAC blower without a call, but only if the outdoor air temperature
is within the high and low ventilation temperature limits.
+ If the outdoor air temperature is outside of the limits at the end of the
one-hour cycle period, then no additional ventilation will occur for
another 60 minutes, and the cycle period will automatically adjust to
four hours. The controller will then attempt to meet the set amount of
ventilation during the four-hour cycle period.
+ If the air temperature is still out of range at the end of the four-hour
cycle period, the control will automatically switch to an eight-hour cycle
period, then a 12-hour cycle period and finally a 24-hour cycle period.
During eight, 12 and 24 hour cycle periods, the total ventilation time
increases to compensate for ventilation effectiveness as defined in
ASHRAE Standard 62.2-2010.
+ When the cycle period automatically adjusts to 24-hours, the control
will turn on ventilation to meet the requirements even if the temperature
is outside of the set limits.

SEQUENCE OF OPERATION – “COMFORT” SETTING
+ The control will open the vent damper with a heating, cooling or fan
call if the outdoor air temperature is within the high and low ventilation
temperature limits and the indoor RH is within the high and low RH
limits, for the set number of minutes during a one-hour cycle period.
+ If the HVAC equipment does not turn on enough to meet the ventilation
time within the hour, the control will open the vent damper and turn on
the HVAC fan without a call, if the outdoor air temperature and indoor
RH is within the set limits. If the outdoor temperature or indoor RH are
outside of the set limits, then no ventilation will occur.
