INTRODUCTION AND COMPLIANCE STATEMENT
The Model 8191 and 8192 Ventilator with Dehumidification is designed to bring outdoor air into today’s efficiently designed homes while
removing moisture from the air. Simply duct the inlet of the ventilator to an outdoor air intake and duct the discharge to the return side of the
HVAC system. Plug the unit in, set the amount of needed ventilation and set the humidity limit.
High temperature limits can be set on the control to prevent bringing in outdoor air during the hottest period of the day. The built in control will
automatically compensate for the ventilation time that is missed by bringing in additional outdoor air during cooler periods of the day. Compliance
with the requirements of ASHRAE 62.2-2010 is met as the control adds ventilation time as needed to account for the fractional on-time and
effectiveness of the ventilation schedule. The control will also ensure that ventilation occurs no less than one hour of every four. When properly
installed and set, the Model 8191 and 8192 Ventilator with Dehumidification will meet the mechanical ventilation requirements of:
