hi all,i have 1x mitsi heavy ind outdoor model fdc200vs on r410a gas 3x indoor cassettes model
fdt71wf.when switched to test run on heat/cool units run breifly then controller screen (fixed type) goes blank.It switches back on then does the same.the controller led flashes red continously.
it works if units are set to fan only.i have not tested any further because of heavy rain.
Has anyone any ideas,i thought it maybe held off by a bms system,but then as stated it stays
on if units are on fan only,also units do heat or cool for a short time if outdoor unit is switched
off/on again,no fault codes showing on controller.
thanks doorswing.
