Filtration System
The 62X Series units are equipped with either a 2-in. (MERV 8
pleated) filter or a 4-in. (MERV 8, 11 or 14 pleated) filter (located
before the DX coil). A metal mesh screen is used on the outdoor
air intake to prevent larger debris from entering the unit. For units
equipped with the optional energy recovery ventilator (ERV), 2-in.
MERV 8 pleated filters are located on the outdoor air and return
air entrances of the wheel.
Energy Recovery Ventilator
The 62X units are available with an optional belt driven, rotary en
-
ergy recovery ventilator (ERV). The ERV can have multiple diam
-
eters and thicknesses. The ERVs are available with optional VFD
defrost and optional wheel bypass.
Exhaust Fan
The 62X units with a return exhaust configuration are available
with an optional factory-installed direct drive exhaust fan. Exhaust
fans can be airfoil (AF) or backward inclined (BI) type and are
available in multiple fan sizes. Exhaust fans are available with op
-
tional harsh environment coating. Fan motors range from 1/2 to
15 hp and are available in open drip proof (ODP), totally enclosed
fan cooled (TEFC), or electronically commutated motors (ECM).
TEFC and ODP motors have a factory-installed VFD as standard.
Supply Fan
All 62X units include a factory-installed direct drive supply fan.
Supply fans can be airfoil (AF) or backward incline (BI) type and
are available in multiple fan sizes. Supply fans are available with
optional harsh environment coating. Fan motors range from
1
/
2
to
15 hp and are available in open drip proof (ODP), totally enclosed

individual components (ex. supply fan, compressors, air damper,
HGRH) or can enable optional components for individual control
(condenser fans, ERV, etc.). Controller configuration, set point ad

ler.
NOTE: Equipment Touch requires external 24VDC power. Do not
power the Equipment Touch from the Rnet Port.
Some of the features of the LS-1628 controller include:
• Easy access to set points, schedules, status, and unit con

figuration via local or remote interface
• Built-in password protection to prevent unauthorized ac

• Built in timer for compressor protection
• Factory configured control program archive
• Service test and diagnostic mode
• Controller mounted on/off switch for easy power cycling
• Fully integrated webpage for easy communication port
configuration via SERVICE PORT connection
• Integrated LEDs (light-emitting diodes) to display control

ler and I/O operation
• eMMC Flash memory back-up to maintain time and date
in event of a power outage
NOTE: The OptiCORE controller has a 32-bit ARM Cortex-A8,
600MHz, processor with multi-level cache memory / 16 GBs
eMMC Flash memory and 256 MB DDR3 DRAM.
Control Configuration
The OptiCORE controller is preprogrammed and prewired from
the factory to reflect the factory configuration and factory installed
options for each unit. Any field modifications of the unit must be
updated in the unit control configuration.
