Issue:
Very Low Evaporator Refrigerant Pressure diagnostic may be annunciated after performing a circuit lockout. Unlike previous products, even if the circuit associated with the suction pressure is locked out, it will not defeat the protection afforded by this diagnostic.
Resolution:
To continue with the Circuit Lockout without the diagnostic, unplug the suction transducer on this circuit. It will generate a diagnostic Comm Loss: Suction Refrigerant Pressure but will allow the other circuit to run.
