A Damper Control Package is used to control the temperature in two rooms. Only one room per cycle will be controlled using only one Air Handler. There are two motorized dampers connected to the supply air and two motorized dampers connected to the return air. One set of dampers will be connected to Room 1 (Supply and Return) which will be configured as the “OPEN” state and one set of dampers will be connected to Room 2 (Supply and Return) which will be configured as the “CLOSED” state.

When Room 1 is “ON” both the supply and return dampers will be open and the room’s digital thermostat will become energized. When Room 2 is “ON” the motorized dampers from Room 1 will close and Room 2 will open. On the flip Room 1 thermostat will turn off while Room 2 becomes energized.
