When used in conjunction with the VVT® Zoning System and 3V™ Control System the duct temperature sensor is required for use with a bypass controller and must be installed in the supply air duct.
For bypass systems, the duct temperature sensor should be moved to a location which will provide the best sensing of the supply-air temperature during heating and cooling.
For bypass systems, the duct temperature sensor should be located in the main supply duct downstream of the discharge of the air source and before the bypass damper to allow good mixing of the supply airstream.
