Wiring Installation
The wire for the communication stub must be the same that is used for BACnet communication link
wiring. Refer to the section,
“Zone Sensor Mounting and Wiring,” p. 24
Duct Temperature Sensor Wiring
The Symbio
210 controller has one analog input for a discharge air sensor, which can be user-
configured for supply air temperature. The typical mounting position of the supply air sensor is
upstream of the VAV unit and connected into the Symbio
210 controller at AI3 and
(refer to the
illustration below). However, the discharge air temperature sensor may be downstream of the VAV
unit (at the discharge) and connected into the Symbio
210 controller at AI3 and
. Refer to the
“Appendix: Typical Trane Factory Wiring Diagrams,” p. 73
. For standalone VAV units (those not
connected to BACnet link), an air supply sensor is needed for auto-changeover from cooling to
heating mode or from heating to cooling mode.
