VISIONPRO® 8000 SMART THERMOSTAT
Residential,
Commercial
or Both
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.
