Carel pCOe expansion card 24VAC NEW

Carel expansion board typically used in Condaria VAR and high-end marine AC systems for adding components to the main board.  Power input is 24VAC or 24VDC.  

Installation tips:  The dip-switches must match the dip-switches on the defective board.  If you do not know the serial address, it should be noted on the wiring diagram.  The serial protocol dipswitches are not often used.  Next to the dipswitches are lights that show power (yellow) and data.  Red or no lights are not good.  On some systems this PCOE expansion board only reads whatever is connected (pump current etc) to it and has no input to how the AC unit functions.  Questions?  Email us.  We are the experts.
