Hi, John Howie :)

Can you explain this in plain english, please?
Also can you tell us something more about your compressors, refrigerant, set points, PLC if any and so;)
Best regards, Josip :)

Is this a direct expansion system (sounds like that) or a pumped circulation system.
Probably TEV's not EEV's, wouldn't be uncommon with TEV's especially with low loads and the valves not just selected with this in mind.
