The Daikin-McQuay 6026873 Control Board RXN18NMVJU is an electronic component used to organise the work of the element, and control the communication between internal units in HVAC systems. Its operation relies on a printed circuit board that acquires signals from sensors and thermostats processing and disseminating electrical impulses to motors, valves, and other apparatus when ductless mini-split HVAC systems are in operation. It is fitted within the equipment control compartment, in which wiring harnesses, are attached to the terminal points and the circuit handles equipment responses.
