Take the NAT to the residential district and go flip the junction box next to CJs. It should force the quest to continue and direct you to go up into an apartment in Athena tower. The whole time the 47b junction box marker will still be on but just keep ignoring it and complete the quest. Hope that works for you!

Overview. With minimal pressure drop and low noise levels the SDV controls the airflow rate of conditioned air into an occupied space in response to a thermostat control signal. Incorporation of an airflow sensor allows the SDV to compensate instantly for any change in supply air pressure that might alter the supply volume resulting in a pressure independent variable air volume . The calculations for main supply airflow for VAV reheat systems were changed between version 6.3.2 and 6.3.3. In version 6.3.2 and before, the program always used the cooling load to calculate the main supply airflow for the system. The main supply heating airflow was then calculated based on the main supply cooling airflow.and single-zone VAV air-handling systems. VAV terminal units. The guideline includes sequences for the following configurations of VAV terminal units: • VAV terminal unit (cooling-only, no heat) • VAV terminal unit with a reheat coil • Parallel fan-powered VAV terminal unit with a constant-speed fan • Parallel fan-powered VAV terminal unit

Hey guys, just got a call that the reheat coils for a job we did are not working (when thermostat set higher, heaters not kicking in). Now these are five 8" titus single duct boxes with 2kw heaters. The heating cfm's range from 90-120cfm. I think that they are heating the air too high and tripping a high limit cutout.
Multi Zone-VAV equipment has variable speed supply fans and is often used in Variable Air Volume (VAV) systems consisting of ductwork serving multiple building zones and VAV boxes that control space comfort independent of the rooftop air handler. VAV boxes modulate air volume by a damper that opens and closes to maintain space comfort.
Similar to the constant-volume system, at design conditions the VAV system will balance the same 40,000 Btu/hr [11,724 W] space sensible load with the same 1,840 cfm [0.87 m3/s] of 55°F [12.8°C] supply air.

Rule 3) The Zone VAV box size is not allowed to be less than the sum of the attached room VAV minimums. In other words, one can oversize the room diffusers but the zone VAV box, since it is based on the block load, will in reality, only see the highest actual zone block airflow or the sum of the room VAV minimums, whichever is larger.controller is factory installed on Trane® Variable-Air-V olume (VAV) terminal units, the factory will download the unit with the appropriate VAV programs and configuration settings for the unit. These can include sales-order- specified airflow setpoints. Trane VAV units are made with either pneumatic or microprocessor controls (DDC/VAV). This
Today’s VAV is a planet-friendly way to deliver targeted zoned comfort to every part of the building. Intelligent systems control the temperature and indoor air quality for multiple zones from one or more large, self-contained units per floor. Inside, VAV boxes that serve multiple zones can provide cooling and heating as needed.requirements limiting the use of reheat for humidity control (section 6.5.2.3). There are several exceptions covering a variety of permissible reheat applications: • Exception 1: variable air volume systems which reheat 50 percent or less of the design .ing setpoint by adjusting the setpoint for VAV-box primary airfl ow. • VAV-box airfl ow is sensed and maintained at setpoint by adjusting the position of the VAV-box damper. • For zones that need reheat, zone temperature is sensed and maintained at the heating setpoint by adjusting reheat capacity (electric reheat or a hot water valve .Trane® Zoned Rooftop Systems Components of Trane® Zoned Rooftop Systems p. 3 Zoned Rooftop System Confi gurations p. 4 Systems comparison p. 10 Application considerations p. 12 Equipment with controls: Light commercial rooftop units p. 28 Equipment with controls: VAV terminal units p. 35 Equipment with controls: Bypass damper p. 37 Sensors p. 38
The VAV with reheat terminal device is used to control the supply air of a VAV system using a VAV damper. The terminal box also contains a reheat coil to heat supply air before it enters the space. Library Type: Equipment: Heating Coil: Electric
