OUTDOOR RESET FUNCTION

SELECTIONS

(Optional on Heating Boilers Only)

As an option, the Excel 10 control may be equipped with an outdoor reset function. This function uses a sensor to measure the outdoor temperature and automatically adjust the boiler set point temperature to compensate for colder outdoor temperatures. O.A. Min, Max, SetPoint and Setpoint Temp are changeable points from the Command Display. The additional values required by the Excel 10 to properly operate the reset function should be specified at the time a boiler is ordered. If specific settings are not available the default values will be programmed into the Excel 10 at the factory. The operating parameters for the reset function are:

O.A. Lockout — The maximum outdoor air temperature where the boiler will continue to operate. When the outdoor temperature rises above this setting, no heat should be needed for the building and the boiler will lockout and not fire. The default setting if not specified is 70.0°F (21.1°C). This setting should be specified at the time the boiler is ordered.

O.A. Max — The warmest outdoor air temperature where the boiler reset function will begin to function and operate the boiler at the initial set point temperature. The boiler set point will increase based on a corresponding drop in outdoor temperature below this temperature. The default setting if not specified is 60.0°F (15.6°C).

O.A. Min — The coldest outdoor air temperature where the boiler reset function will reach a maximum boiler water temperature (Max. SetPoint). No additional reset (increase) in boiler temperature will occur past this point as outdoor temperature continues to drop lower. The default setting if not specified is 10.0°F (-12.2°C). This setting is a Changeable Point from the Command Display.

O.A. Temp. — A display of the outdoor air temperature as sensed by the outdoor air sensor.

Max. SetPoint — The maximum water temperature that the boiler or water heater may be set to operate at. The default setting if not specified is 220.0°F (104.4°C). This setting is a Changeable Point from the Command Display.
