MF2 Series ™ MICROFLO II Product Family The Invensys MICROFLO II family of direct digital controllers (DDC) is compatible with pressure independent and pressure dependent variable air volume terminal box applications. The MICROFLO II controllers operate in a stand-alone mode providing accurate zone temperature control and can be integrated into a facility-wide BAS/DDC system by utilizing the I/A Series family of controllers. Invensys Building Systems provides an integrated Building Automation System capable of meeting the tough control strategies of today’s VAV Air Systems. The MICROFLO II family of controllers may be applied to new VAV terminals or retrofitted to existing electric, electronic or pneumatic actuated air terminals.  Standard sequence for morning warmup using primary air when Models of the MICROFLO II family support standard butterfly used with a heat/cool VAV AHU. damper terminal boxes, pneumatic terminal boxes and boxes with existing integral actuators. In addition, the MICROFLO II family of  Reheat options are integral to controller for application to all controllers provides compatibility with all types of terminal box and types of terminal box and perimeter reheat. radiation reheat, along with integrated zone lighting control,  Optional local pushbutton override at wall sensor provides timed helping to make the MICROFLO II family the most comprehensive override of unoccupied conditions and enables start up of line of DDC VAV terminal box controllers available in today's central system and zone lighting. market.
