7. Select a Ventilation Priority (see Fig. 232):
c. Lockouts are Priority: The thermostat places a pri-
ority on lockouts versus the ASHRAE 62.2 ventilation
standard. The thermostat will not run ventilation dur-
ing the following lockout conditions (if configured)
unless you manually call for ventilation:
(1) Lockout Ventilation during Outdoor Conditions
(ISU 1013)
(2) Lockout Ventilation on Humidification or Dehu-
midification Calls (ISU 1014)
(3) Lockout Ventilation during "Sleep" (Residential) or
"Unoccupied" (Commercial) program periods.
Note: This option is set by the user on the Ventila-
tion screen in the Menu.
d. ASHRAE is Priority: ASHRAE requires additional
ventilation following a long off cycle. The thermostat
meets the ASHRAE 62.2 ventilation standard by run-
ning additional ventilation when outdoor conditions
are favorable. If ASHRAE cannot be met when out-
door conditions are favorable, the thermostat will
override the outdoor lockouts and run ventilation.

Meets ASHRAE 62.2
Ventilation will run
21% of the time
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.
NOTE: 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.
