Key functions include weekly weather forecast, system information, define holiday schedule, temperature trend, and Wi-Fi setup. Settings include backlight, clock, clean screen, installer, display, backlight settings, customized appearance, clock settings, and pause touch function. Advanced settings are available with caution.
• Page 6: The Backlight Settings window allows you to adjust the Halo backlight intensity based on two conditions: when the screen is touched or when it is idle. An ambient light sensor enables the backlight to adjust automatically according to room lighting levels. You can enter holiday periods into the Halo memory. A holiday period begins and ends at midnight on the specified days, during which holiday event settings override the regular weekly schedule. Trend will provide you with a zoom-able record of the last few days room temperature and set temperatures. This is useful for evaluating system performance or confirming correct comfort levels. The Info window should be your first stop if you encounter issues with your SMT-850 “Halo” or your heating and cooling system. This window provides details on how your SMT-850 “Halo” is configured, what actions it is requesting, and whether any errors are being reported.
• Page 7: Selecting your modes: heating, cooling, or off. The mode function bar allows you to select different modes for your SMT-850 'Halo' thermostat. Heat only mode activates your heating system to maintain your desired warmth. Cool only mode activates your cooling system to keep your home or office cool. Auto mode monitors the room temperature and automatically switches between heating and cooling. Fan mode offers advanced fan control capabilities. You can choose whether the fan runs continuously (On) or only when needed (Auto). Your installer may have enabled more advanced fan logic features. If enabled, you can select the speed at which the fan runs. The SMT-850 will show the available speeds based on your heating or cooling system.
• Page 8: Temperature control Adjusting temperature Press the up or down button next to the mode (heating or cooling) you want to adjust. A fly-out ribbon may appear, asking you to choose how long this new temperature should remain before automatically returning to its previous value. Select the desired override period. In commercial programmable mode, the SMT-850 Halo has built-in features to minimize energy waste. You won’t be able to adjust the stop event temperature. If the “override” icon is displayed, press this icon first to enable climate adjustments. The override period will automatically cancel after a preset time. You can cancel the override period prior to it expiring by tapping the “overridden to” ribbon.
• Page 9: Schedule - Residential Mode If your SMT-850 Halo thermostat is set up by your installer, the residential scheduling function may be enabled. This allows the thermostat to automatically adjust your home temperature according to your lifestyle. The SMT-850 Halo can preheat or precool your home before you wake up in the morning. Maintain an energy-efficient temperature while you're at work. Preheat or precool your home before you return from work. Set a comfortable temperature while you sleep. Editing the schedule is simple. Select the days of the week you want to edit. Adjust event times and temperatures using the up or down buttons. Your SMT-850 Halo thermostat will follow the updated temperature profile.
• Page 10: Schedule - Commercial Mode If your SMT-850 Halo thermostat is set up by your installer, the commercial scheduling function may be enabled. This allows the thermostat to automatically turn your office HVAC system on and off based on occupancy attendance times. The Halo also offers a separate holiday scheduling function to prevent the HVAC system from running during extended periods of absence. Editing your schedule is simple. Select days of the week you want to edit. Adjust event times and temperatures by selecting the start and stop times as well as the start temperature.
