Maximum temperature control on modulating stage

For this function a boiler supply temperature sensor (“SupplyTemp”), located in the boiler itself, must be connected. The modulating stage has a high limit override control, according to the setpoint and the P-band, defined by parameter BST-03 and BST-05. The maximum control signal for modulating control varies from 0...100% as shown in the next figure.
