This Pressure Transmitter option enables the 200DX to continuously and automatically maintain the indoor/outdoor pressure differential target of 2.5Pa max, dependent on the air tightness of your home or building.
This pressure device is not intended for compensating for make-up air conditions, but rather provides greater control over relative building pressure. A balanced or slightly positive indoor air pressure will minimize the amount of harmful contaminants (both harmful for occupants and the structure). Using the pressure transmitter option is an effective method to prevent mold growth inside the wall cavities and the building structure.
When using the Pressure Controller, sudden changes in pressure will not cause instantaneous changes in flow.The BAPI Pressure Controller tracks and records indoor/outdoor pressure changes over 10 minute intervals to make the necessary adjustments to airflow in 8CFM steps.
Note: The UltimateAir 200DX comes default with the ability to offset air flows up to 60CFM. Please see the 200DX manual for more information about flow offsets.
