• update includes new string values for Nexus Liquid Cooled alarms
• Improvements to auto-detect based on testing with Nexus Liquid Cooled model. LiquidCooled conf option is now optional
• Added more display messages for 2-wire start / stop

• Added alarm code check battery for Nexus controllers
• Added more Nexus air cooled alarm codes
• Corrected problem with outage log not displaying outages longer than 24 hours. Thanks Irma
