Central control Mitsubishi

[multisync]

My boss rang me to say that I have to go and look at a Mitsubishi VRF with 8 indoor units. The 'fault' is that 6 of the 8 controllers are showing "central control" and won't work.The other 2 are ok.

Now I don't ever remember seeing a G50 on the system so I can't understand why this should suddenly show up?

Boss put them off till Monday when he said we'll (me)sort it out no problems

EEEK and more importantly HELP

on the controllers there will be a plug for centrally controled u can remove it and just use the controler

older models its in the controller. newer its in the fan coil pcb.

Got to site and phoned Mitsubishi tech.

The guy said "Oh that's easy, they have been locked off, press the temp up and filter button till 'centrally controlled' disappears"

Tried it and it did..
