Make-Up Air Tempering Switch Example
Connections from these terminals will have to be made
to the respective supply fan terminals R, W1 (if used),
and Y1 (if used). Use proper gauge wire for field wiring
depending on the voltage used.
When connecting to Greenheck's tempered Make-Up
Air unit, connect R, W1 (if used), and Y1 (if used) up to
the supply unit and land on R, W1 (if used), and Y1 (if
used). This will be 24 VAC power, so 18 AWG shielded
wire should be utilized.

Combination Fan/Light Switch

• To terminals S1H and S1

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