well we are installing our first Hitachi units 1 inceiling ducted 5 wall mounts and 1 under ceiling

What a load of ****e..

Easier to install -my arse !!

oh don't forget to wrap the mains wires LN+E three times round the magnents(supplied) coz their electronics isn't up to it...

oh don't forget you must use screened cable and as you have 240 and 24 v you must run 2 cables coz their electronics isn't up to it..

you can power to the outside but to remove the (supplied) cable means you have to dismantle the indoor unit !!!!

underceiling unit to fit the 'wireless remote ' option

first WIRE the WIRELESS remote base unit and run the cable down the wall !!

what a bloody larf. what is the point of having a wireless remote option if you have to wire in a base unit which (unlike the Daikin) won't go into the actual unit....???

jeezus Hitachi wot a load of rubbish..

forget 'em and stick to Daikin

cheers
