Set Point Parameters Screen:
The Set Point Screen allows access to 12 parameters. Those parameters are as follows:
•User Set Point - Sets the water temperature set point for fixed temperature operation or the maximum temperature set point when the outdoor air sensor is used. This parameter can be changed by the user or the installer. The temperature range of this parameter is 50° to 190°F. The default value is 125°F.
•Hot Water Tank Set Point - When a tank sensor is installed in a hot water storage tank, the hot water tank set point sets the target temperature of the water in the tank. This parameter can be changed by the user or the installer. The temperature range of this parameter is 60° to 185°F. The default value is 125°F.
•Hot Water Tank Differential - Sets how many degrees below the Hot Water Tank Set Point the hot water tank temperature must drop before the boiler will turn on. This parameter can only be changed by the installer. The temperature range for this parameter is 0° to 100°F. The default value is 5°F.
•Indirect HW Set Point - When a Hot Water Generation call for heat becomes active, the control will use the Indirect HW set point to determine the firing rate of the boiler based on the actual boiler outlet water temperature. This parameter can be changed by the user or the installer. The temperature range of this parameter is 50° to 190°F. The default value is 180°F.
•Night Setback Set Point - Once the internal clock has been set correctly, the night setback feature can be used to program a lower water temperature set point for space heating. This parameter can be changed by the user or the installer. The temperature range for this parameter is 32° to 140°F. This feature is turned off with a setting of 32°F. The default value is 32°F.
•Minimum User Set Point - Sets the minimum water temperature set point that can be used for space heating operation.
