About this file
This document is a Single Duct Terminal Unit Schedule specification for variable air volume (VAV) units manufactured by Titus. The schedule specifies four VAV units (VAV-01 through VAV-04) with DESV models in sizes 06 and 08, configured for integration with air handling units (AHUs). The units are sized to deliver between 200 and 900 CFM at maximum capacity, with minimum airflows ranging from 200 to 250 CFM. All units operate at 480/3-phase electrical service with modulating SCR electric heat coils rated between 2.5 and 3 KW, featuring single-step heating control with heating performance validated per ASHRAE 130-2008 and AHRI 880-2011 standards.
Electrical specifications include minimum supply circuit ampacity (MCA) ratings between 3.8 and 4.5 amperes and maximum overcurrent protection (MOP) ratings of 15 amperes across all units. Units feature noise control levels of NC 55, with entering air temperatures (EAT) at 55 degrees Fahrenheit and leaving air temperatures (LAT) between 92.9 and 94.5 degrees Fahrenheit. All selections incorporate altitude corrections, and the specifications are validated against AHRI 885-2008 Appendix E for NC level determination. The document carries a standard disclaimer that results serve only as design aids and do not substitute for professional design services, with all data subject to change without notice.

1. Selections are based on Titus as Manufacturer.
2. All performance based on tests conducted in accordance with ASHRAE 130-2008 and AHRI 880-2011.
3. All NC levels determined using AHRI 885-2008 Appendix E.
4. All airflow, pressure losses and heating performance values have been corrected for altitude.
5. Units of measure: dimensions (in), airflow (cfm), water flow (gpm), air pressure (in wg), water head losses (ft) and temperatures (degF).
6. In the "Steps" column, code "S" denotes a modulating SCR heater.
7. The minimum supply circuit ampacity (MCA) and maximum overcurrent protection (MOP) ratings were calculated in accordance with UL standards based on motor and electric coil full load current ratings.
