The following advanced settings are available:
•Synch Time to Server: If the thermostat is connected to a Wi-Fi
router, both the date and time are synced with the server based on
the timezone of the smart device used to connect the thermostat to
the router.
•Screen Timeout: Allows you to specify how long the backlight of
the thermostat remains on after you stop interacting with it. The
options are 5, 10, 15, 20, 25, or 30 seconds.
•Proximity: Allows you to enable or disable presence detection. If
you enable the proximity feature, the backlight of the thermostat
activates when the thermostat sensor detects user presence.
•Prox Sensitivity: Allows you to adjust the sensitivity of the proxim-
ity feature. The default setting is medium and you can change this
to high or low. High sensitivity increases the detection range of the
thermostat sensor.
•Daylight Savings: Allows you to enable or disable Daylight Sav-
ings. The default setting is enabled.
•Wireless: Allows you to enable or disable the Wi-Fi functionality of
the thermostat. The default setting is enabled.
•Sound: Allows you to adjust the thermostat sound. The options
are OFF, CLICK, or BEEP. The default option is CLICK. See Fig-
ure 21.

Understanding Schedule Settings
On the Schedule Settings screen, tap the buttons to enable the required
schedule settings. When a setting is enabled, a check mark is displayed.
Use the scroll bar to view all options.
As shown in Figure 22, you can choose one of the following modes:
•Programmable: This mode allows you to set up heating and cool-
ing setpoints for four periods in each day of the week. These peri-
ods are referred to as day parts in this document. When you select
Programmable mode, the default schedule is displayed on the
Schedule screen. You can edit the default schedule as required
using the Edit Schedule screen.
•Non-Programmable: This means that the thermostat runs in a
simplified mode that satisfies the selected heating or cooling set-
points. In this mode, the Edit Schedule icon does not appear
because the scheduling functionality is disabled.
You can change the mode you have selected if required. To do so, go to
the Schedule Settings screen and tap the button for the required mode.
