Carrier’s Fan Coil Open Controller is an integrated component of a Carrier fan coil unit. The Fan Coil Open controller continuously monitors and regulates fan coil operation with reliability and precision. This advanced controller features a sophisticated, factory-engineered control program that provides optimum performance and energy efficiency. The Fan Coil Open controller also features plug-and-play connectivity to the Carrier i-Vu Building Automation System.
For added flexibility, the Fan Coil Open controller is capable of stand-alone operation, or it can be integrated with any Building Automation System utilizing the BACnet protocol.
Product Integrated Controller
Integrated controller for fan coil units capable of stand-alone operation or integrated with Carrier’s or any Building Automation System using BACnet®, Modbus® or Lonworks® protocol
| BACNet Support | Advanced application controller (B-AAC), as defined in BACNet 135-2001 Annex L |
| Communication Ports |
Network port: EIA-485 port for BACnet MS/TP communications (baud rates is DIP switch selectable) Comm Option Port: For connecting a LON Option Card (future) 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 |
2 binary inputs: Remote Occupancy Contact/Fan Status and Condensate Overflow 4 analog inputs: RH/CO2 (0-5VDC), SAT (10k thermistor), RAT/T55 (10k thermistor) and Changeover Switch (dry contact)/Changeover Sensor (10k thermistor). AIs have 10 bit A/D resolution. |
| Outputs |
5 binary outputs: High Speed Fan, Medium Speed Fan, Low Speed Fan, Two-Pipe Valve/Heating Valve/Electric Heat Stage 1, and Cooling Valve/Electric Heat Stage 1 with Type 5 Heat and 2-Pipe. Relay contacts rated at 1 A max @ 24 VAC/VDC, configured normally open. 3 analog outputs: OA Damper, 2-Pipe/Heating Valve and Cooling Valve. AOs rated at 0-10VDC, 5mA max with 8 bit A/D resolution using filtered PWM. |
| 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, power, and all digital outputs. |
| Controller Addressing | Rotary DIP switches set BACnet MS/TP MAC address of controller. |
