VCCX2 Controller Technical Guide
Features
The VCCX2 Controller is designed with eight analog inputs,
four analog outputs, eight binary inputs, and eight relay outputs
(seven congurable). It also has an on-board BACnet
®
port for
connection to an MS/TP network. The VCCX2 contains a 2 x 8
LCD character display and four buttons that allow for status and
alarm display, force modes, and BACnet
®
conguration.
The VCCX2 Controller can communicate with the Refrigerant
System Module for VFD Compressors, Refrigerant System
Module for VFD Compressors - Heat Pump, Refrigerant System
Module for Digital Compressors, and Refrigerant System
Module for VFD Compressors (RZ or RN-E units with Danfoss
compressors). In addition, the VCC-X EM1 Expansion Module
and 12 Relay E-BUS Expansion Module provide additional
inputs and outputs.
There are two E-BUS Expansion Connectors on the VCCX2
which allow for the connection of the expansion modules listed
above, communicating sensors, and future E-BUS modules via
modular E-BUS cables. There are presently seven communicating
sensors available.
• E-BUS Digital Space Temperature Sensor
• E-BUS Digital Space Temperature and Humidity Sensor
• E-BUS Space Temperature and Humidity Sensor
• E-BUS Space CO
