Notes:
• Supply and return coil connections are on the same side.
• In 4-pipe systems, the cooling coil connections are on the opposite end from the heating coil
connections.
• DX coils are always left-hand connections.
• Electric heat coils are always right-hand connections.
• Heating coils (hot water or steam) are right-hand when in the reheat position with DX cooling
coils.

Notes:
1. All coil types on the left side of the grid are available in single-coil, heating only, or 2-pipe changeover with exception of coil type A.
2. For 2-coil or 4-pipe systems, select the cooling coil on the left side of the grid. An X corresponds to a valid heating coil combination.
3. Shaded areas signify valid selections with face and bypass dampers.
