This manual covers the operation, installation, features, protection functions, test mode, and commissioning of the Temperzone UC6 unit controller.
The Temperzone Unit Controller 6 (UC6) is a successor to the OUC4 controller designed for indoor, outdoor, and packaged units. It combines a µPC controller board with an interface board to manage refrigeration circuits, electronic expansion valves, fans, and compressors while ensuring unit safety through continuous monitoring of inputs like pressures and temperatures.
The document details lower and upper board connections, including power supply requirements (24V AC), digital and analogue input/output signals, and communication ports such as RS485. It also describes operational modes for heating, de-icing, and demand response management, along with various protection functions like high pressure protection and compressor lock-out.
The UC6 is powered by 24V ±10% AC and requires a class 2 safety transformer with a minimum rating of 24VA.
Yes, one controller can manage two complete refrigeration circuits.
Press and hold the push button on the lower board for 1 to 5 seconds, provided both compressors are OFF.
