Hi there

Newbie here, so apologies first of all
I rent an apartment and my landlord is away for 6 weeks so can't ask him what's going on so thought i would try here.
My power cut out the other day, and when i turned it back on the inside air con unit made a noise and the vent moved and reset itself but ever since then the Operation light is flashing green continuously.
I have tried the remote and pressed every conceivable button to turn on or reset the unit but nothing is happening. Incidentally the remote display changes to reflect what button is pushed.
I've even tried tripping the fuse box again in the hope that it will reset itself, but no such luck
Any ideas at all? I wouldn't ordinarily worry but the nights are expected to hit minus 1 here in a couple of days and i'll freeze without my warm air con lol.

Thanks in advance for any help.

T.
