Morning all.

I'm a mechanical supervisor and my company are close to completing a large residential project in London.
The house has 4 separate VRV systems throughout and the units are heat pumps.

The system was commissioned about 6 weeks ago by our subcontract installer. On doing my final walk round yesterday, I noticed that some of the wall mounted remotes don't seem to be displaying all of the information. (there are 12 in total)

On 5 of the RC's, when you press the Operation mode button you can scroll through, Auto/Dry/Heat/Cool /Fan (which I believe is correct)
4 of them only show Heat/Fan/Dry and 3 only show Cool/Fan/Dry ??
Why are some of these operation modes not displayed on certain controllers?

I've looked through the menu's and nothing jumped out at me as a parameter that could be changed. It is my understanding that all options should be available?

I've got the installers coming back on Monday but would like a heads up on what the problem might be. Hopefully it's something simple.

Thanks in advance.
