Basic type C: Chilled water flow temperature control.
With an upward adjustment of the setpoint, the water can take a very long time to
warm up if the valves are closed and the pipe is well insulated. Here, the message
delay is set to 10 hours in order to avoid unnecessary fault status messages. It is
very likely that the valves do not close properly, if, after 10 hours, there is still a
setpoint deviation.
15.8 Control timeout
You can define a control timeout period (TIMEOUT) in order, for example, to
prevent the cooling valve from opening immediately after the heating valve closes.
The controller does not add the integral action component during that period of
time.
