Description
The York S1-02546845000 ECO RAH Sensor Harness is a wiring harness used in economizer system to connect the return air humidity or enthalpy to the control board in HVAC systems. It is installed inside compatible rooftop units and air handling system, where it provides the electrical interface between the sensor and the economizer control module. The harness carries low-voltage signals that allow the system to monitor return air conditions such as humidity or enthalpy for economizer control logic. As part of the economizer control assembly, it supports communication between the sensing part.
