External BI-3 Configuration
Set the function of external binary input 3: 0 = ventilation lockout,
RW x 0
1 = exhaust interlock.
External BO-3 Configuration
Set the function of external binary output 3: 0 = auxiliary heat,
RW x 0
1 = exhaust fan on/off signal.
Fan Cycling Configuration
Set if IAF cycles (switches off) during occupied, bypass, and standby
RW x 2

same time after a power failure or occupancy change.
LUI Temperature Units Set LUI temperature display units in degrees F or degrees C. RW x F
 If a menu item value is greater than 2-digits (higher than 99), then
will be displayed by the LUI.
 RW = read and write capable, RO = read only. (All RO values displayed are snapshots and are not dynamically updated as the value is displayed.)
 Additional UVC field configuration is required if the dewpoint/humidity binary input is used, consult the factory.
