Io Hvac Controls SC-Z20-DAS Discharge Air Sensor

Product Description

The IO HVAC CONTROLS SC-Z20-DAS is a discharge air sensor designed to work with the SC-Z20 zone controller in forced-air HVAC systems. It monitors supply air temperature at the discharge point of the air handler or ductwork, feeding real-time data back to the zone controller to support accurate zone-based temperature management. The sensor is a compact unit measuring 4.5 x 9 x 3.5 inches and weighing 0.3 pounds, making it straightforward to position in tight duct or equipment installations. HVAC technicians and controls specialists are the primary installers for this type of accessory sensing device.

This discharge air sensor is intended for use in zoned residential or light commercial forced-air HVAC applications where the SC-Z20 zone controller is already installed or being commissioned. It mounts in the discharge air stream to provide continuous supply temperature feedback, enabling the controller to modulate system operation according to zone demand. Typical installations include split systems, air handlers, and fan coils controlled through a zone panel. The sensor is specifically referenced as a companion accessory to the SC-Z20 system.
