Description
The Daikin-McQuay 5018656 Printed Circuit Assembly is a component used in controlling electrical signals in HVAC systems. This assembly is specifically involved in the relay of messages, processing of inputs and controlling of the other parts such as compressors and fans. It achieves this through regulating voltage and frequency so as to provide the best performance to the compressor besides preventing it from overheating and wearing out. The PCA also has a temperature control mechanism to regulate the speed of the fans to allow adequate air circulation and maintain indoor temperature.
