TSS – Single Duct Variable Air Volume Terminal
TSS Terminals provide Variable Air Volume (VAV) control
beyond the typical single duct box. They are specifically
designed for precise air delivery throughout the entire
operating range, regardless of the installed inlet conditions.
These units can be ordered with or without a Direct Digital
Controller (DDC), which can operate as a stand-alone unit,
on a Johnson Controls N2 trunk, or on a LON
®
trunk.
TSS Terminals take advantage of typical benefits provided
by single duct units, while performing at extremely low
sound levels. This is critical in today’s buildings where
occupants are placing more emphasis on indoor acoustics.
The TSS Terminal is manufactured and assembled with a
multi-point, center-averaging airflow sensor, which
provides a signal to the controller enabling it to quietly and
precisely measure airflow.
Bundled with the TSS Terminal is a digital controller from
the VAV Modular Assembly (VMA) Series or the LN Series.
Each model in the VMA1400 Series and the LN Series
combines a controller, pressure sensor, and actuator
housed in one pre-assembled unit.
• An integrated VAV box with direct digital controls
eliminates the coordination and difficulties
associated with factory mounting
• Downloading of software, setting of parameters,
addressing and testing at the factory reduces
startup time and lowers risk
• Superior flow measuring provides for lower
minimum cubic feet per minute (CFM) values,
which reduces energy costs and noise while
maintaining comforts in the zone
• Installation time can be reduced with the low
profile compact design and standard metal
hanging straps
• Units wired in compliance with all applicable
National Electrical Code (NEC) requirements and
tested in accordance with Air Conditioning and
Refrigeration Institute (ARI) standard 880
• Offers damper stall detection, starved box
detection, actuator motor duty cycle, VAV box
flow test, and other diagnostics on most
models (VMA Series)
