Operation 6.10 Control The internal and external control parameters are preset at the factory for operation as circulation chiller (with water as heat transfer liquid). Depending on the application, adjustments of the control parameters can be necessary from case to case. The thermal capacity and the viscosity of the heat transfer liquid also influence the control behaviour and may require adjustment of the control parameters. 6.10.
Operation Other precautions The viscosity of the heat transfer liquid changes very strongly with the temperature. The liquids have higher viscosity at low temperatures. Therefore, the control quality is generally worse at low temperatures. For this reason, the controller should be set at the lower end of the temperature range to be covered. If the control is stable at low temperatures, then it is generally also stable at high temperatures.
Operation If the proportional range is selected too small, the P part on the control value is at 100 % for a very long time. This value then reduces more quickly within the proportional range, i.e. the control value reduces rapidly and the approach of the actual value to the setpoint almost comes to a standstill. Due to the I part not becoming effective until now, the actual value approaches the setpoint slowly. Fig.
Operation 6.10.3 Overview of internal control parameters The internal control compares the setpoint value with the outlet temperature and calculates the control value, i.e. the amount to be heated or cooled. The following control parameters can be adjusted for the internal control: Parameter Description Unit Xp Proportional range K Tn Reset time s Tv Lead time s Td Damping time s If Tv manual/auto is set to auto , Tv and Td cannot be changed.
