Toshiba vrf fault

[grovecoooling]

Hi

Please could somebody help.

I had recently installed a Toshiba Vrf 3 pipe system about 3 months ago, all commissioned fine.

I returned to site earlier today and fitted remote return air sensors to each indoor void unit, when I switched the system back on I found fault E04 on the 1st 12 fan coils on the centralised controller, strange as these are not the first 12 from condenser but are 1 to 12 on the centralised.

I need to return to site tomorrow before the office workers return and being a sunday technical support is shut.

Do you think I need to do a master condenser reset, and also does anyone know the E04 error code.

Please help if you can
