Thanks for the reply went back today changed lev head and controller board.
Couple of hours later 1102 fault.
Went to the outdoor pury p200 vgma and it has 1 bc box with 7 indoor pefy ducted units and 5 controllers.
The 1102 fault always comes up on the same controller and has happened since the install of the system.
I reset the system and put all units on heating. High side pressure was 35 bar and suction was 10 bar (r410a) rang Mitsubishi and did dipswitch settings and came out with 29 bar on discharge.
Took temp of discharge at comp and was around 80 degrees c.
When I started running a few on cooling and heating the temperature went up to 100 degrees.
I have noticed that when that controller faults out sometimes it is the only unit running and Mitsubishi think that this could be a reason as it is only a 2 kw.
I am beginning to think that it is overcharged?
Any thoughts
Thanks in advance.
