The Setra FLEX™ provides a flexible room environmental control and
monitoring solution in a simple-to-use package. An attractive flush-mount
faceplate is complemented by an intuitive graphical display to meet any
architectural requirement. The unit supports 3 rooms, monitoring up to
6 parameters for each room. An optional differential pressure sensor can
be either factory-installed in the unit or ordered separately and installed
above the ceiling. Integration with building automation systems is made
easy through either BACnet/IP or BACnet MS/TP network protocols.
Modular design
A modular hardware design enables the FLEX monitor to t in various
wall thickness found around the globe. For applications which require the
monitor to t in wall depths less than 50mm, the FLEX can be ordered with
an external pressure sensor. When mounting in a three gang electrical box,
the FLEX can be ordered with an integrated on-board sensor. Sufcient on-
board I/O provides connectivity for most common equipment and sensor
applications. If additional connections are required, or if more advanced
HVAC applications demand it, FLEX can work directly with a third party
controller over BACnet. A high accuracy 0.25% differential pressure
transducer is used in all pressure sensing options. A projected capacitive
touch screen provides swipe functionality and allows for use with medical
gloves. The faceplate is attached to the unit body, enabling both tamper
resistant operation and easy opening for pressure calibration.
Setra FLEX-RM and FLEX-RC
FLEX software is designed to suit any application, with the ability to support
up to 3 rooms. FLEX-RM (Room Monitor) provides monitoring only, for
those applications where no control from the touch screen is needed.
FLEX-RC (Room Control) offers monitoring, plus PI loop or network control
of VAV boxes, venturi valves, or hydronic reheat valves. Software is pre-
installed, with conguration and network integration done using simple
setup screens. There is no programming required. When completed,
conguration settings on one unit can be cloned to other devices using a
standard USB thumb drive, thereby shortening commissioning time. Units
can also be congured remotely over a BACnet network.
The FLEX monitor is both a controller and monitor, with audible and
visual alarming on all room environmental parameters. The FLEX monitor
enables users to save energy by choosing from two PI control loops and
two monitoring sets for any of four room modes, such as occupied and
unoccupied.
