evening all

got a head-scratcher,recently got sent to a job,my first attendance,found REYQ14M,8 indoor units,all cassettes,condenser on roof,2 units in basement,4 in offices,2 in cashiers,served by bsvq100's) and was told to replace LP sensor,found sensor ok! hooked up my lines!nada..system had nothing in it,0 gauge pressure! factory charge,10.5kgs.

found the problem,replaced faulty EEV body,and motor coil as that was blown!vac'd and re-charged accordingly,ran up sweet,job done.

but when checking indoor units noticed 4 out of the 8 fcu's are positioned in offices and come on when someone enters the room on PIR ceiling sensors which also shuts the units off when there is no movement or occupancy meaning the rooms never reach setpoint and the units are constantly turning on and off and as its a financial institution there's alot of traffic in and out of said offices,all day everyday.

has anyone ever come across this and could it be damaging the inverter and comp or wreaking havoc with pressures and temps?

the outdoor fan never really steps up fully,just slow idle for 10 mins then off?same with the inverter comp also idling over,not stepping up?
indoor temps are next to nothing?even on the other units(not on the sensors)

any help would be much appreciated
