• Get rid of the flat sequence, use wires to enforce dataflow execution!
• Don't split the Modbus reference, use just one reference wire!
• No need to close the same reference twice…
• Cleanup the frontpanel and arrange all those scattered indicators more nicely.
• Do you really need 6 indicators just to display a timestamp?
• Cleanup the block diagram to follow the StyleGuide. Straighten wires, subVIs, …
• Use proper datatypes to avoid unneccessary coercion dots. (Example: HeatPump_temp)
• Do you really need 10 additional indicators just to build on SerialNumber from 5 U16 registers?
• Why do you need to duplicate code 5 times for the conversion of U16 to two chars? Use a loop instead of all that duplicated code!
  Example:
