Accessory - Discharge Air Sensor
Summary:
This discharge air sensing kit is designed to sense the supply air temperature downstream of the fan and/or heat exchanger.
Notes:
- An options board (FIAOPTN002*) must be installed in the unit for this accessory to operate.
- Supply air sensing tube is standard on SZVAV, MZVAV, and economizer units.
- After installation is complete, the Symbio 700 UC module configuration will need to be updated to enable this installed accessory.
