  • Page 98 Effects of viscosity on the heat transfer A control that is stable at low temperatures will usually be stable at high tem- liquid peratures. Conversely, if a system is just about stable at high temperatures, it will most probably be unstable at lower temperatures, i.e. vibrate. The viscosity of the heat transfer liquid changes drastically with the tem- perature.

  • Page 99: Overview Of Internal Control Parameters

    If the proportional range selected is too small, the P-component of the actuating signal remains at 100 % for a long time. This value decreases even faster within the proportional range, i.e. the actuating signal decreases rapidly and the progress of the actual value towards the target value comes almost to a complete stop.
