Daikin-McQuay 1840061 Sensor is a temperature and humidity part that is built to be incorporated into the HVAC systems, such as rooftop units, air handlers, and variable air volume systems. The sensor works through the detection of the conditions in the surrounding air and sends the accurate electrical impulses to the control unit, allowing it to correctly regulate the heating, cooling, and ventilation cycles. Installation is done in the duct or conditioned space, and the unit must be exposed directly to the airflow.
