Page 5: Overview
This module automatically configures condensers, EXVs, and compressors based on unit selection. The RSM-DEV1 uses an E-BUS cable to connect to the VCCX2 Controller. Up to four RSM-DEV1 Modules can be connected. There are two E-BUS expansion ports which allow connection to the VCCX2 Controller, communicating sensors, and other E-BUS modules. -
Page 6: Installation
Please carefully read and apply the following information when wiring the unit controller, RSM-DEV1, and any associated module. Correct wiring of the AAON unit controller and its modules is 1. All wiring is to be in accordance with local and the most important factor in the overall success of the installation national electrical codes and specifications. -
