Hi guys,

Can across the fault with HKXE2D R407c fault error E75.The manual stops till 45 ! The central remo con panl was all lit up and could not move any.Reset power and also of the outside units.All worked but after some time stopped again.
Any idea ?

E75
Central Controller communication error
poor connection, broken wire, faulty controller
Wiring between outdoor units' loop daisy chain and central controller are not clear.
I highly suspected on poor connections... please check.
