Set Point Parameters Screen:

The Set Point Screen allows access to 6 parameters. Those parameters are as follows:

•Hot Water Tank Set Point - 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 On Differential - Sets how many degrees below the Hot Water Tank Set Point the hot water tank temperature must drop before the water heater 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.

•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. 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.

•Drop in Inlet Temperature for Ending Anti-cycling - The control will bypass the anti-cycling time if the inlet water temperature drops too quickly. The control will use the inlet water temperature at Heat Exchanger 1 when it shuts off as the starting point. If the temperature drops below the temperature parameter the control will abort anti-cycling andallowthewaterheatertofire.Thisparametercanonlybe changed by the installer. The temperature range of this parameter is 0° to 86°F. The default value is 10°F.

•Anti-cycling Time - Once a call for heat has been satisfied, a set amount of time must elapse before the control will respond to a new call for heat. The control will block the new call for heat and Anti-cycling will be shown in the water heater status display until the time has elapsed or the inlet water temperature drops below the parameter drop in inlet temperature for ending anti-cycling. This parameter can only be changed by the installer. The time range for this parameter is 0 minutes to 40 minutes. The default value is 1 minute.

•Hot Water Tank Off Differential - Sets how many degrees above the Hot Water Tank Set Point the hot water tank temperature must rise before the water heater will turn off. 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.
