The Control Scheme for Subordinate Dual Duct applications determines how the Setpoints and Output Control Logic are configured. Constant Box Flow configurations are set up so the Hot and Cold Deck Dampers are controlled to maintain constant flow delivery into the space. The Variable Box Flow configurations are set up so the Cold Deck Damper and Hot Deck Damper maintain separate flow setpoints depending on whether the zone requires heating or cooling to maintain heating and cooling zone temperature setpoints.

The selection options for Control Scheme are:

  • Constant Box Flow

  • Variable Box Flow
