Notes:
  • -COMBO:Allows for heating of domestic hot water. This is now the DSH option, designating a refrigerant desuperheater is installed.
  • -H: Horizontal air flow
  • -2: Each C unit has 2 coils. The -2 option indicates 2 separate connections for each coil this option allows for only one of the two coils to be used at a time. It is a 2 stage hydronic(water) cooling coil.
  • E: A slab coil version of the C series A coil design
