  • Application

    The rcc.1081 is designed to be mounted in an un-refrigerated, non-condensing, location inside a refrigerated display case, inside a compressor rack house electrical panel or an electrical panel controlling a walk in freezer/cold room. The rcc.1081 is a multi-function controller capable of executing several refrigeration control strategies.

    • Secondary Loop Case Temperature Control
    • Secondary Fluid Valve Case Temperature Control
    • DX Case Superheat Control using Stepper EEV
    • DX 5-Case EEPR Circuit Control for cases using TXVs
    • DX Case Superheat Control using Pulse EEV
    • Remote I/O Module
