YORK: YVAA R513A 200Ton screw compressor help
Hey tech family! I need some help.
I found this chiller with an alarm for system 1 & sytem 2: warning: Low Discharge Superheat Recovery.
What does this mean. I’ve read a lot on this chiller. Its maintaining 55F setpoint in the 35F ambient temperature but the warning continues to pop up, can anyone help?

“The safety is ignored for the first 10 minutes of operation
if the system economizer feed valve is closed
(0%) and for 5 minutes of operation if the economizer
feed valve is open greater than 0%. If the discharge
superheat falls below 5.0°F for 5 minutes under either
condition, the system will shut down.”2 -
Thanks. I’m not shutting down. But I have noticed they are at low load conditions. I’m seeing just a warning. I have realized that I think it’s the chiller telling me it’s at the low limit point. Think of a vfd when it’s throwing a high amp limit warning. That’s the vfd letting you know it’s at its limit to protect its self. Any thoughts on that?
