View Full Version : mitsubishi controller

21-04-2016, 10:43 PM
I have an AG150 A controller on a vrf system and each indoor unit has an MA30 controller,
some of them can be turned off on the remote controller but others come up with centrally controlled.
I have gone into the AG150 controller and set all units to be not prohibited on the on/off button to no avail.
Anyone any ideas.

Presumably you mean the PAR-30MAA controller. Each controller has to be allocated its own group on the AG150.
Sometimes you can get 'ghost entries' which can cause all sorts of communication problems.
You can link a number of these groups together.
You could have several linked groups which have become accidently cross populated thereby creating the possibility of centralised control from several directions.
