Operation
Image Icons
Image icons are displayed on your screen as touch/press areas. A complete list of them is provided in

text below.
Basic operations
Cool, heat strip, heat pump, and furnace
-
aqua modes are available based on system

medium (if
available), and
automatic. Automatic changes fan speeds as required for improved comfort.
Home, away, and schedule modes provide three different thermostat experiences.
Home mode is the traditional way a thermostat operates, changing at a specific set
point. Away mode provides two set points allowing a wider range of temperatures.
Schedule mode allows changing the temperature up to four times each day.
Adjusting the brightness
The display automatically dims after 25 seconds without a touch. There are two dimming modes
selectable for this feature. Day mode shows the screen but at a dimmer setting. Night mode shows only
a small logo with the rest of the screen black. Brightness adjustment is available for both modes.
