Features and Benefits
AIRFLOW CONFIGURATIONS
Variable Air Volume (VAV)
– TempMaster
®
OmniElite
™
units are available for variable air
volume (VAV) applications. Control can be used with a zone sensor or building automa-
tion system (BAS). Supply 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.
Single Zone Variable Air Volume (SZVAV) –
TempMaster OmniElite 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 (SAT) 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 dis-
charge plenum, downstream of the supply fan. The SAT sensor is located across the face
of the supply duct opening in the unit. Furnaces are designed in 375 mbh modules. Three
stages are available for the TMAL120–150. 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 SAT sensor is located across the face of the supply duct opening in the unit.
Furnaces are designed in 375 mbh modules in 8:1 turndown increments. Three are avail-
able for the TMAL120–150 (8:1, 16:1 or 24:1 turndown). Ignition 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.
Hot Water Heat –
For applications where hot water is available for heating, a hot water
heating coil is available. A range of coil fin count selections are available to properly size
the heating for the application. Units with hot water heat are ETL listed.
Steam Heat –
For applications where steam is available for heating, a steam heating coil
is available. A range of coil fin count selections are available to properly size the heating
for the application. Units with steam heat are ETL listed.
