Night Setback Override

Any Night Setback On trigger currently active or scheduled within the next seven (7) days can be skipped. To skip a trigger, rotate the NAVIGATION dial until the arrow (>) is next to the trigger you wish to skip. Press the NAVIGATION dial once. “SK” will appear next to that trigger to indicate that it will be skipped. You can restore an upcoming trigger by selecting that trigger, and pressing the NAVIGATION dial again. The “SK” next to that trigger will disappear.

To save any changes and return to the Home Screen, press the RIGHT SELECT [HOME] key. To return to the Status Screen without saving the changes, press the LEFT SELECT [EXIT] key.

Temperature Units

The control can be configured to display temperature in either °F or °C. This parameter can be changed by the user or the installer by accessing the Temperature Units parameter. The default is °F. To change the temperature units, access the clock menu as described in the User section (this page). Rotate the NAVIGATION dial until the arrow (>) is pointing to “TEMPERATURE UNIT °F”. Press the NAVIGATION dial once. The temperature unit will begin to flash. Rotate the NAVIGATION dial until the desired temperature unit is shown. Save the new setting as described in the Saving Parameters section (page 10).

Space heating (SH1, SH2, SH3) and tank set points

CAUTION	Mixing valves are required for the
	protection of any low temperature loops.

In compliance with Energy Conservation Standards, this boiler is equipped with outdoor air reset, a feature that saves energy by reducing the boiler water temperature as the heating load decreases. Three (3) individual outdoor resets for low outdoor temperatures are available. The reset curve parameters can be changed by the installer by accessing the Outdoor Reset menu.

There are three (3) individual user set points for better zone control. These are listed as SH1 Set Point through SH3 Set Point. These set points provide a maximum boiler water temperature limit to the outdoor reset curve of each zone. The boiler operating set point is calculated from the individual reset curve of each zone. If multiple space heating set points are calling for heat the highest set point has priority. The range is SH Minimum Set point to SH Maximum Set point (32°F (0°C) - 190°F (88°C)). The default is 125°F (52°C).

By installing a tank sensor, the SMART SYSTEM control can perform the tank thermostat function. The SMART SYSTEM control automatically detects the presence of this sensor, and generates a DHW call for heat when the tank temperature drops 6°F (-14°C) below the tank set point differential (Tank Set point Differential parameter), and finishes the call for heat when the tank temperature reaches tank set point + offset. This parameter can be changed by the installer by accessing the DHW Tank Set point parameter. The temperature range of this parameter is 68°F (20°C) to 190°F (88°C). The default value is 125°F (52°C).

Press the NAVIGATION dial once. A menu will appear showing the SH1, SH2, SH3, and DHW Set Points. Rotate the NAVIGATION dial until the arrow (>) is pointing to the setting you wish to change. Press the NAVIGATION dial again. The value of the selected setting will begin to flash. Rotate the NAVIGATION dial to adjust the value. Save the new setting as described in the Saving Parameters section (page 10).
