Aprilaire 8533 - Manual (Page 11)

Changing The Current Temperature Setting
1. Press and release either the DECREASE button or INCREASE button to see the current
temperature setting. The setting, a Thermometer icon and a Double Arrowhead icon will appear
(see Figures 2 and 3 on pages 5 and 6).
2. Change the temperature setting:
OPTION 1 – Use the DECREASE button or INCREASE button. Press and hold the
DECREASE button or INCREASE button to change the current temperature setting.
The thermostat remembers the most recent temperature settings. For example, if the Day, Cool
temperature shown in Figure 3 were changed from 78˚F to 76˚F, the 76˚F setting would remain in
memory as the Day, Cool setting.
Note: The Cool temperature setting must be a minimum of 2˚F higher than the Heat temperature
setting for both the Day and Night sets. The thermostat will automatically update the setting not
being changed. In the example above, if the Day, Heat setting was 75˚F, the thermostat would
have automatically changed the setting to 74˚F when the Cool setting was changed to 76˚F.
OPTION 2 – Use the DAY/NIGHT button. Press the DAY/NIGHT button to instantly change the
temperature setting to one of the two settings stored in memory.
