SMXII-AB Control Display/Keypad (replacement) DX

New SMXII-AB Replacement Control Display/Keypad This display replaces original Cruisair displays used in SMX control systems. All displays have the original four pin display cable jack on the back of the display. This is an all new replacement module that includes the buttons and electronics needed to communicate with the control board. The DX version is used in directly connected compressor systems and features button labels printed directly on the buttons. Faceplate is not included nor available. The TW version is used in tempered or chilled water systems. These systems use a water loop containing glycol or fresh water to supply the air handler controlled by this display.
