Evening all

has anyone come across any issues arising from connecting tiny 1.5/2kw units on to a large (100kw) VRF system. We have a few on a system serving small 2m2 rooms and we suspect, when only one is operating in auto, the FCUs changeover too quickly and the system trips out.

There are several cassettes on the system, the majority are 10KW units but around five of them 2kw units at the very end of the piperun. Like distances all check out and the system runs beautifully when all units are in demand.

any advice anyone may help would be much appreciated.
