  • This video is a really quick but step by step setup of a CAREL pRack for operating 1 compressor which is on a Variable Speed Drive and 2 Fans which are on EC drives. The compressor has 4 alarms plus 1 VSD alarm and the condenser side has 1 alarm feedback. Its explains simply the setup and some details about logic. These times work well for 1 compressor setup. In multiple compressor setups some settings not used would need to be adjusted. The controller has 100s of features , this just touches on essential settings to operate an air cooled condensing unit. I assumed medium temperature R404A but if pressures are changed it can work for other refrigerants too. Thank you.
