in this video we're going to step
through the various functions of the
Paragon hpac HMI HMI stands for human
machine interface and is the device used
to navigate the Paragon hbac software
the Paragon hbac can be used in many
varying applications it should be noted
that each unit is configured
specifically for its application it is
strongly recommended to communicate with
tech support sales or service team prior
to making adjustments to prevent
unintended operation every Paragon unit
will have at least one unit mounted HMI
with a possibility up to four additional
space hmis each space HMI can sample
temperature humidity and CO2 of their
installation location and contribute
towards an overall average if this is
their intended use they can also be used
solely for display purposes or a
combination of both is acceptable as
well HMI sampled conditions can be
waited to create a better representation
of exact space conditions the HMI is
navigated by using four buttons on the
outside of the LCD display two are on
the left and two are on the right once
on a menu and not on the main screen the
two left buttons up and down are used to
go up or down in a menu and the right
two buttons enter and back are used to
enter into and back out of menu levels
enter drills into the highlighted
section and back backs out one level
pressing back enough times will return
you to the main screen each hmis
temperature is sampled by two adjacent
sensors located near the bottom of the
face plate between the lower two
screws the HMI also has an integrated
relative humidity sensor that will
sample and display the humidity relative
temperature each of these sensor
readings should be compared to test
equipment such as a thermometer and
pyrometer to verify reading
accuracy each HMI also contains a CO2
sensor that will sample space carbon
dioxide levels to provide further
improved indoor air quality
potential the Paragon hbac can be
configured to achieve optimal space CO2
ranges displayed in parts per million
this provides us more data points to
Monitor and control that will contribute
to op optimized indoor air
quality one important note is that the
space hmis should be installed with
their Factory provided vented standoff
to allow for more accurate space
readings care should be taken to ensure
the HMI readings are not skewed by
poorly insulated wall cavities or
excessive space temperature swings
caused by variables such as a sliding
entry door space heaters appliances or
other factors that could skew readings
we recommend space hmis are located in a
room not impacted by sunlight while
giving the best representation of
average space conditions typically near
a return space hmis should never be
installed in an area with a draft or
diffuser upon arrival the unit or space
hmis will likely be in screen saver mode
the screen saver can be enabled and
configured per the customer's preference
to display date and time temperature
date and time temperature only or
temperature and relative humidity we'll
discuss modifying the screen saver in a
video pressing any button will wake the
HMI and display the main screen
on the main screen you'll see the date
day of the week time space or discharge
temperature and climate control State
you'll also see a temp plus and temp
minus button and possibly an onof or
override button if your unit has
scheduling enabled you'll likely just
see a temp plus and temp minus button
and whether the unit is occupied or
unoccupied per the schedule defined in
user settings which we'll discuss in a
