MHI remote control lock

Good Evening,

Does anyone know if you can lock any settings on a Mitsi Heavy remote control (the older LCD type). We would like to lock temperature, modes, etc if possible.

All help much appreciated.

Regards

Try one of these.....

Thanks Brian but I don't think the office staff will like this too much;).

I could just do with a setting from the remote controller's service function if possible.

Thanks
