i-Vu® Building Automation System UC Open Controller

  • California Prop 65


General Purpose Controller

Universal programmable controller provides auxiliary building control to interface with lighting, fans, pumps, and other HVAC equipment. 6 inputs/5 outputs.

The UC Open controller provides auxiliary building control to interface with lighting, fans, pumps, and other HVAC equipment. The UC Open’s factory-engineered control programs provide simple building integration for commercial applications with 11 I/O point capability.



Application Features

  • Comprehensive library of factory-engineered control programs available, including: Pump Control, Lighting Control, Time Scheduling with/without Override, Analog Temperature Control, Discrete & Permissive Interlock, Discrete Staging Control, OA Conditions, BTU Metering, Fuel Oil Metering, Electric Metering, Gas Metering, and Water Metering
  • Supports Snap graphical programming for creating customized control programs
  • Supports Carrier communicating room sensors, which allow for local setpoint adjustment and local overrides

Hardware Features

  • Real time-clock keeps time in the event of power failure
  • Stand-alone control of up to 11 I/O points using proven algorithms
  • Native BACnet MS/TP communications

System Benefits

  • Fully plug-and-play with the Carrier i-Vu Building Automation System
  • Supports demand limiting for maximum energy savings


BACNet Support Advanced application controller (B-AAC), as defined in BACNet 135-2001 Annex L
Communication Ports BACNet Port: EIA-485 port for BACnet MS/TP communications (9600 bps, 19.2 kbps, 38.4 kbps, and 76.8 kbps)
Local Access port: For system start-up and troubleshooting (115.2 kbps)
Rnet port: For connecting Carrier communicating room sensors and Carrier's touchscreen user interface
Inputs 6 inputs: Configurable for thermistor or dry contact. Inputs 1 and 2 are also configurable for 0-5 VDC sensors. AIs have 12 bit A/D resolution.
Outputs 5 binary outputs: Relay contacts rated at 1 A max @ 24 VAC/VDC, configured normally open.
Protection Incoming power and network connections are protected by non-replaceable internal solidstate polyswitches that reset themselves when the condition that causes a fault returns to normal. The power, network, input, and output connections are also protected against voltage transient and surge events.
Real Time Clock Battery-backed real time clock keeps track of time in event of power failure.
Battery 10-year Lithium CR2032 battery provides a minimum of 10,000 hours of trend data & time retention during power outages.
Status Indicators LED status indicators for communications, run status, error, and power.
Controller Addressing Rotary DIP switches set BACnet MS/TP MAC address of controller.
