Make-Up Air (MUA) Interface (Optional)
When the KFCC is interfaced with another Greenheck
supply air unit, this option will omit the redundant
starter in the KFCC, as the supply air unit will already be
provided with one. This will be 24 VAC voltage; so 18
AWG, shielded control wire can be utilized.
