i-Vu® Fan Coil Open OPN-FC
i-Vu® Fan Coil Open
OPN-FC
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
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.
Application Features
- Controls modulating or 2-position hot water/steam valves or up to 1 stage of electric heat to maintain space temperature setpoint
- Controls modulating or 2-position chilled water valves or a single stage of DX cooling to maintain space temperature setpoint
- Controls 2-position outside air damper to meet ASHRAE® 62 ventilation requirements
- Built-in advanced control routines for zone level humidity control or zone level demand control ventilation (ASHRAE 62)
- Optimal start and PID control for maximum occupant comfort
- Automatic fan speed control for matching fan speed to actual cooling or heating requirements, thus allowing the fan to run at the lowest capable setting to maintain room setpoint
Hardware Features
- Compatible with 42D, 42C, 42S, and 42V fan coils
- Integrates easily into any BAS using the BACnet MS/TP protocol
- On-board hardware clock, remote occupancy input, and support for Carrier communicating and thermistor sensors provides stand-alone operation
- Thermostat linkage allows up to 8 fan coils to operate from 1 sensor
- Easy startup and commissioning using Carrier’s i-Vu user interfaces
System Benefits
- Fully plug-and-play with the Carrier i-Vu Building Automation System
- Supports demand limiting for maximum energy savings
- Compatible with i-Vu Tenant Billing for tracking tenants’ afterhours energy usage
| 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.
