DPT-Ctrl-2SP is designed for simple systems to control constant pressure or air flow of fans, VAV systems or dampers. The device has a binary input to select between two user-adjustable setpoints. When controlling air flow, it is possible to select a fan manufacturer or a common measuring probe that has a K-value. The device also includes a temperature sensor input which enables compensation of flow or pressure according to for example outside temperature.

 

DPT-Ctrl-2SP can be used to control air flow or constant pressure in applications where it is important to keep a constant vacuum or steady air flow. Energy savings and optimal indoor air quality can be achieved because of the two setpoints and the outdoor temperature compensation feature of the device. The desired setpoint can be selected, for example, with weekly clock, turn switch or key card switch.
