Features and Benefits
AIRFLOW CONFIGURATIONS
Variable Air Volume (VAV) –
Series 100 units are available for variable air volume (VAV)
applications. Control can be used with a zone sensor or building automation system. Sup-
ply fans are controlled to the supply duct static pressure setpoint, which can be reset via a
building automation system (BAS) or through a 0–5VDC analog input on the unit controller
for optimized duct static pressure control. The static pressure transducer is provided in the
single package unit, and 5/16-inch or 1/4-inch plastic tubing and static pressure sensor
must be supplied by others and installed approximately 3/4 down the longest duct run.

Underfloor Air VAV –
Series 100 units are configurable for underfloor air VAV
applications. Control can be used with a zone sensor or building automation system. Sup-
ply fans are controlled to the supply duct static pressure setpoint, which can be reset via
a BAS, or through a 0–5VDC analog input on the unit controller for optimized duct static
pressure control. The static pressure transducer is provided in the single package unit,
and 5/16-inch or 1/4-inch plastic tubing and static pressure sensor must be supplied by
others and installed approximately 3/4 down the longest duct run.
Refer to 100.50-EG8
engineering guide for more detailed information on this application.
Single Zone Variable Air Volume (SZVAV)–
Series 100 units are available for single
zone variable air volume (SZVAV) applications. Control can be used with a zone sensor
or a BAS. Supply fans are controlled based on zone temperature.
COOLING AND HEATING CONFIGURATIONS
Cooling Only –
For applications where no heat is required, or heating is provided else
-
where within the building HVAC system, cooling only units include an empty discharge
plenum. Supply duct connections are configurable for bottom, left or right discharge. The
supply air temperature sensor is included and factory-installed.
Staged Gas Heat
–
For applications requiring gas heat for morning warm-up, or other
heating needs, a staged natural gas furnace is available. The furnace is located in the
discharge plenum, downstream of the supply fan. The supply air temperature sensor is
located across the face of the supply duct opening in the unit. Furnaces are designed in
375 MBH modules with two stages in each. For 70–105 ton units, optional Propane Con-
version Kits contain the necessary orifices and gas valve/parts to convert staged heat only
(not modulating) from natural gas to propane. Ignition and safety controls are included
and factory-wired. Units with staged gas heat are ETL listed.
Modulating Gas Heat
–
For applications requiring gas heat for morning warm-up, supply
air tempering or other heating needs, a modulating natural gas furnace is available for
finer temperature control. The furnace is located in the discharge plenum, downstream of
the supply fan. The supply air temperature sensor is located across the face of the sup-
ply duct opening in the unit. Furnaces are designed in 375 MBH modules in 8:1 turndown
increments. Three are available for the YPAL070–105 (8:1, 16:1 or 24:1 turndown). Igni-
tion and safety controls are included and factory-wired. Units with modulating gas heat
are ETL listed.
Electric Resistance Heat –
For applications where electric heat is desired, a slip-in elec-
tric resistance heat element is available in sizes from 80–250 kW depending on the single
package unit model size. The number of stages varies by size and voltage, but all have a
minimum of two stages of capacity. Units with electric heat are ETL listed.
