511.06-N3Y HEAT ANTICIPATOR SETPOINTS It is important that the anticipator setpoint be correct. Too high of a setting will result in longer heat cycles and a greater temperature swing in the conditioned space. Reducing the value below the correct setpoint will give shorter “ON” cycles and may result in the lowering of the temperture within the conditioned space. Refer to the Heat Anticipator Setting Table for the required heat anticipator setting. TABLE 13 - HEAT ANTICIPATOR SETTING SETTING, AMP
