What is your question? Are you getting false alarms, or are the alarms correct? Perhaps the heating medium is getting cooled down by rain falling on the distribution piping?

When asking questions or seeking help, it is always important to put as much relevant information as your can.

  • What type of alarms are these? High temperature alarms? Low temperature alarms? Defective sensor alarms?
  • If the temperature transmitter was giving the alarm, why did you replace the digital actuator controller? What type of defect was it? Water infiltration? Not responding? What's the connection with the temperature alarm?

Since we haven't seen your installation, it's important to give us some information before we can offer any real help. All we can do is guess.
