The gradient calculation will be used to predict the time to reach the required setpoint. The allowed time to reach this setpoint is defined by parameter SST-09. This calculation will be done to establish if the desired setpoint can be reached within the allowed time. If the setpoint can be reached in a shorter time than parameter SST-09, there is no need to switch on more heat generator capacity. When the setpoint can’t be reached within the time of parameter SST-09, more heat generator capacity will be switched on. The calculated time to reach the setpoint is displayed in parameter DISP-04.
