Both unit is for stand by use only. When the fresh start signal sent, "low discharge superheat" alarm occur only on circuit #1 after 30 minutes. After alarm reset, everything back to normal. apply to before it trip, manually switch off and then switch on back. Anyone got this kind of problem?

to be sure you have to measure the super heat , discharge temp.

is the unit equiped with electronic exp device ?
if so check the lp temp sensor.
