Time Calculation to Reach Setpoint

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.
