Configuration The ViewStat Color Communicating Thermostat provides the current temperature, controls and displays humidity, and displays the current outdoor temperature. The ViewStat Color Communicating Thermostat displays this information on a 3.5" (8.89 cm) color display. In addition, the ViewStat Color Communicating Thermostat provides the current day's weather forecast along with a five-day forecast, driven from AMX's i!-Weather application. This chapter provides information about the different screens on the ViewStat Color Communicating Thermostat, how to navigate through them, and how to establish settings on each screen. Front Panel Components This section describes the front panel components and gives instructions for operating the ViewStat Color Communicating Thermostat (see FIG. 1). Display The ViewStat Color Communicating Thermostat provides the current temperature condition including indoor and outdoor temperature, the current weather conditions, and the Five Day Forecast. The thermostat displays this information on a 3.5" (8.89 cm) color QVGA (320 x 240) Thin Film Transistor Liquid Crystal Display (TFT-LCD). Display Navigation buttons Mode/Select button FIG. 1 Front panel components ViewStat Color Communicating Thermostat User Guide 3 Setup and Configuration Navigation Buttons The ViewStat Color Communicating Thermostat is equipped with three tactile buttons that support the thermostat's main functions and its backlight options. When you press any button, the display backlight lights up for 30 seconds. The Navigation buttons are used to change various parameters on the thermostat, including the temperature setpoints. These buttons are located beneath the faceplate. Mode/Select Button The Mode/Select button is used to navigate through the various thermostat screens, including the weather screens. This button is located beneath the faceplate. Navigating the ViewStat Color Communicating Thermostat This section describes the various screens on the thermostat, and the options on each screen. Main Screen Current room temperature Cool setting FIG. 2 Main screen Heat setting Current forecast 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. Pressing Mode/Select takes you to the Current Weather screen. Pressing either of the navigation buttons takes you to the Hold Mode screen. 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. 4 ViewStat Color Communicating Thermostat User Guide Setup and Configuration Current Weather Screen FIG. 3 Current Weather screen The Current Weather screen (FIG. 3) displays a detailed description of the day's weather forecast. This screen includes the outdoor temperature, the expected high and low temperatures for the current day, the wind chill/heat index temperature, the wind direction and speed, the percent humidity, the dew point, and barometric pressure. The ViewStat Color Communicating Thermostat receives this information from AMX's i!-Weather service. This screen is view-only. You can disable this screen so it does not appear when you navigate through the thermostat's screens. See the Disabling the Forecast Screens section on page 32 for more information. Pressing Mode/Select takes you to the 5-Day Forecast screen. This screen returns to the main screen after a 20-second timeout. ViewStat Color Communicating Thermostat User Guide 5 Setup and Configuration 5-Day Forecast Screen FIG. 4 5-Day Forecast screen The 5-Day Forecast screen (FIG. 4) displays the high and low temperatures and the expected weather condition for each of the next five days. The ViewStat Color Communicating Thermostat receives this information from AMX's i!-Weather service. This screen is view-only. You can disable this screen so it does not appear when you navigate through the thermostat's screens. See the Disabling the Forecast Screens section on page 32 for more information. Pressing Mode/Select takes you to the Thermostat Mode screen. This screen returns to the main screen after a 20-second timeout. 6 ViewStat Color Communicating Thermostat User Guide Thermostat Mode Screen FIG. 5 Thermostat Mode screen Setup and Configuration The Thermostat Mode screen (FIG. 5) displays a menu providing a list that enables you to navigate to other screens to create settings for different times and occasions.

Energy Star recommends that a programmable thermostat be capable of maintaining room temperature swings within ± 2°F of the set point temperature. You can choose from 0.5°F, 1.0°F, and 2.0°F (or 0.25°C, 0.5°C, 1.0°C). The default value is 0.5°F (0.25°C). Second Stage Diff Enables you to set the 2nd stage temperature differential. You can choose from 1.0°F, 2.0°F, 3.0°F, 4.0°F, 5.0°F, and 6.0°F (or 0.5°C, 1.0°C, 1.5°C, 2.0°C, 2.5°C, 3.0°C). The default value is 2.0°F (1.0°C). Deadband The Deadband is the temperature difference between the heating and cooling setpoints. The Deadband configuration enforces a minimum separation between the two setpoints which determine when auto changeover between HVAC heating and cooling mode will occur. You can choose from 2.0°F, 3.0°F, 4.0°F, and 5.0°F. The default Deadband is 4.0°F. Temperature Offset The temperature offset enables you to customize the temperature shown on the display. You can set the temperature offset in 1° increments. The default temperature offset is 0. Balance Point Balance Point configuration enables you to adjust a low or high balance point to limit auxiliary heat pump operation according to the current outdoor temperature. The compressor terminals will not be energized when the outdoor temperature is below the balance point. This does not affect Emergency Heat operation. This option is only valid if the thermostat has been configured to operate as a heat pump. The default Balance Point is 30°F. This option is only available if your thermostat is configured to operate as a heat pump. Exit Returns you to the Advanced Setup screen.

Viewing the Daily Forecast The Main screen of the ViewStat Color Communicating Thermostat displays the current date, time, and indoor temperature. You can also view the current heating and cooling setpoints you have set and the humidity percentage. The current day's forecasted high and low temperatures and weather condition appears on the bottom of the screen. The Current Weather screen displays a detailed description of the day's weather forecast. This screen includes the outdoor temperature, the expected high and low temperatures for the current day, the wind chill/heat index temperature, the wind direction and speed, the percent humidity, the dew point, and barometric pressure. The 5-Day Forecast screen displays the high and low temperatures and the expected weather condition for each of the next five days. The ViewStat Color Communicating Thermostat receives this information from AMX's i!-Weather service. These screens are view-only. Perform the following steps to view the daily forecast: 1. From the Main screen, press Mode/Select to access the Current Weather screen (see FIG. 17). FIG. 17 Current Weather screen 2. Press Mode/Select to access the 5-Day Forecast screen (see FIG. 18).
