Navigating the ViewStat Color Communicating Thermostat
This section describes the various screens on the thermostat, and the options on each screen.
Main Screen
The Main screen (FIG. 2) of the ViewStat Color Communicating Thermostat displays the current date,
time, and indoor temperature. You can also view the current heating and cooling setpoints and the
humidity. The current day’s forecasted high and low temperatures and weather condition appear on the
bottom of the screen. The ViewStat Color Communicating Thermostat receives this information from
AMX’s i!-Weather service. This screen is view-only.

The thermostat allows the HVAC system to recover gradually from an energy-saving setpoint
temperature to a comfort setpoint temperature. This feature provides comfort while minimizing the
on-time of the HVAC system during the recovery period.
For example, if you set your Wake time and temperature to 72 degrees F at 6:00am, at 4:00am, the
HVAC system begins to gradually adjust the temperature toward 72 degrees. By slowly and
gradually adjusting the temperature, the thermostat saves energy, as opposed to continuously
running the HVAC system beginning at 6:00am until the system reaches the temperature setpoint.
In the hours before a programmed period of the day begins, you may see a slight difference in
expected room temperature. The difference is due to the energy-saving gradual temperature
adjustment.
