11 HM211 TIME PROPORTIONAL
11.1
The following section outlines
components needed to set up the
HM211 to achieve the time
propertional temperature control of
the OM5428 IC. Components that are
common to this and other applications
are included in the uncommitted
module and will not need to be added.
This application might have a variety
of uses for temperature control
applications, such as water bed, room

DESCRIPTION
those parts provided on the
uncommitted board.
Most of these components are axial
leaded components which can be
hand formed and soldered in place
using a normal soldering iron and
electronic solder.
Tolerances for these components are
listed at 1% as these will ensure
tighter temperature control when an
accurate temperature range is
paramount.
