Fault Codes

What is a fault code?

This is how the fault code is shown on the screen.

Self diagnostics is a feature of Hiper HIUs that use the electronic PID controller.

For every component that sends
information to the controller, malfunctions can be detected.

For every functional component that receives instructions from the controller malfunctions can be detected.

When a fault is detected it is displayed on the HIU controller screen as a code.

Where to look for fault code lists?

Fault code lists can be found:

  • Installation and operation manual
  • Controller programming guide
  • Commissioning report

As part of this training module now go to the Inta HIU website, find and download both these documents, and find the page for Error Codes…

File these for future use.

Our latest guides and manuals are available on request.

If you would like hands on training with our HIPER II HIU, please contact HIUtechnical@intatec.co.uk or call 01889 272 196, to speak with one of our specialist team members.

Trouble Shooting

To quote the Internet;

Troubleshooting is the process of diagnosing the source of a problem’.

It is a logical, systematic search for the source of a problem in order to solve it, and make the product or process operational again.

  1. Clearly identify the problem, and identify is it a ‘new’ installation or a ‘break down’.
  2. Always check the obvious first.
  3. Is a fault code showing?
  4. No fault code? Then consult the trouble shooting flow chart in the installation manual.
  5. Step by step follow the path through the HIU.
  6. Diagnose a solution.

Step One: Ask the obvious

Step TWO: Fault Codes*

Is there a fault code?

If YES – then diagnose the problem from the list of error codes.

This list can be found:

  • In the installation manual
  • In the programming guide
  • In the User guide

All these documents can be found on the Inta HIU website and can be downloaded.

A service engineer should have these at hand for immediate reference.

Using fault codes in detail – see Training Module 7

Step Three: No Fault Code

Find reference to the problem in the Fault Finding section in the Installation Manual.

  • Page 19 – Performance issues
  • Page 20 – No hot water reported
  • Page 21 – No heating reported
  • Page 22 – No power?

Summary

  1. Make the diagnosis.
  2. Can this be resolved by the installer on site? MOST important for the end user is that the problem is solved as quickly as possible. This is Inta’s responsibility.
  3. Important – take the serial number of the HIU.
  4. Warranty or non-warranty problem has to be made clear.
  5. The service engineer should report the diagnosis to Inta and wait for instruction to
    send a replacement part if it is needed.
  6. If a solution is not identified or can not be rectified on site, then a purchase order
    should be sent to Inta to organise a service agent to visit.
  7. Warranty issues will be covered by Inta.
  8. Installation issues will be charged at a pre-arranged cost.
