DescriptionLiebert RAC2-8 Series Auto-Changeover ControllersThe Liebert RAC2-8 remotely controls from two to eight environmental units. Each unit is assigned to a Zone (room) from 1 to 4. In Zone 1, the largest room, the temperature and humidity can be monitored. The common alarm output from each unit is monitored and annunciated by the RAC2-8. Up to 20 system alarms can be stored with time and date stamp. All alarms are latching and must be manually cleared.The most important control functions are Autochangeover, Autosequencing, and Standby Testing. Each unit can be assigned a Running or Standby status.Autochangeover turns on a Standby unit if a Running unit in the same zone has an alarm. The Running unit (with alarm) will be turned off if that control option is selected. Each unit will return to its previous status when the alarm is manually cleared.Autosequencing balances unit run-times by changing Standby units to Running (and Running units to Standby) at programmed time intervals.Standby Testing turns on Standby units at programmed intervals to test their operation. Note that Autosequencing and Standby Testing cannot both be selected at the same time.
