Daikin Intelligent Touch Manager web server default username and password

[hallb15]

Bit of a long shot, but does anyone have Daikin Intelligent Touch Manager heating control and know the default username and password for the built-in web server?

To cut a long story short, we have one and I'm trying to get into the web interface so I can set it through a browser rather than the awful touch screen menu system.

The model number is DCM601A51.

 

I've tried the usual admin/password and also a few that I found for similar devices but I can't find credentials that work for this device.
