I have "No Link" showing on my new heat pump display. What does this mean?

Modified on Tue, 22 Aug 2023 at 03:45 PM

If you have a new heat pump, or an existing heat pump with a recently replaced display that shows "No Link", then please carry out the following to see if it remedys the issue:


• Press & hold the UP, DOWN and ENTER keys on the keypad together until "Display address settings" appears on the display.


• Press ENTER to change the position of the cursor and use the arrow UP or DOWN buttons to make the change to the address.


• The heat pump manager itself is referred to as the "I/O Board" and is always given the address of 1.

The number "2" or "3" should be selected for the Display Address.


• Press ENTER again to access the next menu.

To exit, change the "OK?" prompt from No to Yes in the right hand corner of the screen and confirm by pressing ENTER.


Power the heat pump off, then back on again and after a brief period of showing "No Link", around a minute later the heat pump should startup and show the correct menus on screen as expected. If "No Link" persists after a couple of minutes, it is likely to be either an issue with the link cable between the screen and heat pump controller, or possibly a faulty display screen / faulty main heat pump controller.
