Mitsubishi Electric Test Mode

[Northdude]

Hi, can anybody tell me how to put a Mitsubishi Electric FDC506HES3 split system into test cooling? It uses a hard wired controller and there is no test button just a check button. Looked on the web but cant find anything. Thanks in advance.

Looks like a Mitsi Heavy Industries model number.
Outdoors there's dip switches, details should be on the front panel.
From the remote if memory serves correct hold down check then you can select test run of unit or drain pump. Press the select button to, er, select. Something along those lines anyhow.

Cheers,
Andy.
