Save energy by monitoring pressure in exhaust and supply air vents and outputting a signal to adjust fan speed to maintain a desired chase/vent pressure set point as volume changes. The MPCI can be used directly with most ECM powered fans or in conjunction with a VFD to control the speed of 3-phase motor powered fans.

The MPCI includes a controller with integral pressure transducer, factory preset parameters that fit a majority of applications that can easily be field adjusted with the simple two-button interface and an integral UC1 burner circuit interlock for mechanical draft and combustion air applications. MAC-Series expansion modules are available so multiple burner circuits can be interlocked with a single MPCI Controller.
