Notes
None: The thermostat does not control ventilation.
ERV/HRV: The thermostat controls an Energy Recovery Ventilator or Heat Recovery Ventilator for ventila-
tion.
Passive (Fan Only): The thermostat turns on the fan for ventilation. When set to passive fan, the thermo-
stat does not control a damper or ventilator. The passive ventilation/passive fan setting only runs the indoor
blower fan. This setting does not open a damper or run a ventilator. To use this setting for ventilation, the home
would need to be set-up with a pipe from outdoors into the return duct that is either permanently open or has a
damper that automatically opens whenever the blower fan is on.
Note: Some models only offer the passive fan setting.
Note: Options of this ISU may vary depending on the model of the thermostat.
Thermostat: The thermostat turns on the ventilation and the fan when ventilation is needed.
Equipment: Ventilation equipment controls the blower fan.
This ISU is only displayed when ISU 1005 Ventilation Method is set to ASHRAE 2010 or 2013.
This ISU is only displayed when ISU 1005 Ventilation Method is set to ASHRAE 2010 or 2013.
This ISU is only displayed when ISU 1005 Ventilation Method is set to ASHRAE 2010 or 2013.
The thermostat operates ventilation equipment based on a percentage entered in the installer setup (ISU
1012). For example, if Percent on Time is set to 50%, the ventilation equipment will run at random times dur-
ing a 1 hour period until it reaches a 50% run time (approximately 30 minutes). This ISU is only displayed if
ISU 1005 is set to Percent On Time.
Lockouts are Priority: The thermostat places a priority on lockouts versus the ASHRAE 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, 1014 and 1015).
Lockout Ventilation during "Sleep" 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 ventilation standard by running additional ventilation when outdoor conditions are favor-
able. 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 that you increase the rate (CFM) of
the ventilation equipment to meet the ASHRAE ventilation standard in a shorter run time. The ability to lockout
ventilation during the "Sleep" is not an option when you select ASHRAE is Priority.
