Client has a system with a master and sub bc.
Outdoor pury300 plus 200 ylm .
Sub bc is doing nothing on cooling.
The master bc works fine . When the units connected to the master bc box are turned off with just the sub bc box units on cooling the condenser runs but there is no cooling on the sub bc.
Lev3 just stays at 60. None of the valves open on the box .
I'm thinking that there is an issue with lev3 .
Has anyone come across this issue before .
