Outdoor Reset Parameters Screen:

When the outdoor air sensor is installed, the control will calculate the water temperature set point based on the outdoor air temperature. As the outdoor air temperature drops the water temperature set point increases. This feature allows the boiler to be more efficient in periods of mild weather.

The Outdoor Reset Screen allows access to eight (8) parameters. Those parameters are as follows:

Reset Temperature at Low Outdoor Temperature - When the outdoor air temperature drops to its minimum setting, the water temperature will be at this point, if the user set point parameter is set higher. This parameter can only be changed by the installer. The temperature range of this parameter is 0° to 190°F. The default value is 180°F.

Reset Temperature at High Outdoor Temperature - When the outdoor air temperature rises to or above its maximum setting, the water temperature will be at this point. This parameter can only be changed by the

installer. The temperature range of this parameter is 32° to 180°F. The default value is 100°F.

Outdoor Temperature at High Reset Temperature - When the outdoor air temperature drops to this point, the water temperature will be at its maximum setting. However, if the user set point is set lower, the water temperature will be limited by the user set point. This parameter can only be changed by the installer. The temperature rane of this parameter is -22° to 70°F. The default value is 25°F.

Outdoor Temperature at Low Reset Temperature - When the outdoor air temperature rises to or above this point, the water temperature will be at its minimum setting. This parameter can only be changed by the installer. The temperature range of this parameter is 25° to 86°F. The default value is 70°F.

Outdoor Shutdown Set Point - When the outdoor air temperature rises above this point, the control will block all system heat calls. The Hot Water Generation call will be unaffected. This parameter can be changed by the user or the installer. The temperature range of this parameter is 32° to 122°F. The default value is 70°F.

Outdoor Shutdown Differential - The number of degrees below the outdoor shutdown set point that the outdoor air temperature must go before the boiler will respond to a system heat call. This parameter can be changed by the user or the installer. The temperature range of this parameter is 0° to 90°F. The default value is 10°F.

Boost Time - If the boost increment parameter is set to active, the boost time parameter will set the amount of time that must elapse with a system heat call before the water temperature set point will be increased. This parameter can be changed by the user or the installer. The time range for this parameter is 0 minutes to 250 minutes. The default value is 20 minutes.
