1012 Vent Priority
Lockouts
ASHRAE
Lockouts Residential Lockouts are Priority: The thermostat places a
priority on lockouts versus the ASHRAE 62.2
ventilation standard. The thermostat will not run
ventilation during the following lockout
conditions (if configured) unless you manually
call for ventilation:
• Lockout Ventilation during Outdoor Conditions
(ISU 1013)
• Lockout Ventilation on Humidification or
Dehumidification Calls (ISU 1014)
• Lockout Ventilation during “Sleep” (Residential)
or “Unoccupied” (Commercial) program periods.
Note: This option is set by the user on the
Ventilation screen in the Menu.
ASHRAE is Priority: ASHRAE requires
additional ventilation following a long off cycle.
The thermostat meets the ASHRAE 62.2
ventilation standard by running additional
ventilation when outdoor conditions are
favorable. If ASHRAE cannot be met when
outdoor conditions are favorable, the
thermostat will override the outdoor lockouts
and run ventilation. When using this option, it is
recommended to increase the rate (CFM) of the
ventilation equipment to meet the ASHRAE 62.2
ventilation standard in a shorter run time.
Notes:
• ISU 1014 Lockout Ventilation on Humidification or
Dehumidification calls is not an option when you
select ASHRAE is Priority.
• The ability to lockout ventilation during the
“Sleep” or Unoccupied program periods is not an
option when you select ASHRAE is Priority.
