VTR8300 AND VC3000 | LINE-VOLTAGE FAN COIL ROOM CONTROLLERS AND RELAY PACKS

This new cost-effective solution for upgrading line-voltage fan coil unit thermostats requires only two components; the VTR8300 Room Controller and the VC3000 Relay Pack. This solution allows existing line voltage wiring between the fan coil unit and temperature controller to be re-used, thereby reducing overall costs and installation time.
The VC3000 Relay Pack features an onboard universal voltage power supply and line-voltage relays which directly drive fractional horsepower fan motors and valves. This eliminates the need to install and wire costly pilot relays and transformers. The Relay Pack is not required for the VT8300 Series models.

VT8300 LOW-VOLTAGE 24 VAC FAN COIL ROOM CONTROLLERS
This new cost-effective solution for upgrading low-voltage fan coil unit thermostats requires only the VT8300 Room Controller. The VT8300 Room Controller can also be used along with a SC1300 or SC2300 Relay Pack for mixed-voltage solutions, when control of both line-voltage and low-voltage end devices is required.

Occupied Mode Setpoints revert to those defined by occupied cooling and heating.
Stand-by Mode (only available when PIR motion detector sensor is used) Setpoints revert to those defined by stand-by cooling and heating.
Unoccupied Mode Setpoints revert to those defined by unoccupied heating and cooling.
Occupied Override Mode System reverts to occupied mode for duration determined by "ToccTime" parameter.
On Call for Cool Cooling valve opens to maintain room temperature. Heating valve closes. Dehumidification enabled.
On Call for Heat Heating valve opens to maintain room temperature. Cooling valve closes. Dehumidification disabled.

On Demand for Dehumidification Dehumidification is achieved via cooling coil using heating coil for reheat if necessary.
Dehumidification only allowed in COOL mode, or if cooling is enabled in AUTO mode.
Dehumidification disabled if room temperature falls below low ambient lockout temperature, which is cooling setpoint minus configuration defined deadband value.
Reheat disabled if cooling demand reaches 100%.
Options · Wireless adapter modules for BACnet models are available.
(see Appendix B for network wiring).
· Models available with factory installed PIR sensor.
· Remote wall mount or duct sensor ready.
· Can be configured for 2-pipe systems.
· 3 universal inputs can be used and configured for advanced functionality as required by the application.
· Universal input can be configured for changeover sensor.

Sequence of Operation and Wiring
Occupied Mode During Occupied periods, occupied heating and cooling setpoints are used.
Stand-by Mode (only available when PIR motion detector sensor is used) When equipped with a PIR (Passive Infrared) accessory sensor the Controller provides advanced active occupancy logic, which automatically switches occupancy levels from occupied to stand-by to unoccupied when no motion is detected in the room:
· During PIR activated stand-by periods, stand-by heating and cooling setpoints are used.
· During PIR activated unoccupied periods, the unoccupied-by heating and cooling setpoints are used.
Unoccupied Mode During unoccupied periods, unoccupied heating and cooling setpoints are used.
Local Override The Controller reverts back to the occupied mode as specified by a configuration timer when a local override is requested at Controller.

APPENDIX A - PASSIVE INFRA-RED SENSOR SPECIFICATIONS
Passive Infra-Red Sensor Sequence of Operation
Initially, the Controller is in Stand-by mode and Stand-by setpoints are used for the Controller. When the Passive Infra-Red (PIR) sensor detects motion, the Occupancy status switches to Occupied and the Stand-By Time timer is reset. The Occupied setpoints are used for this operation. If no motion is detected in the room for the entire Stand-By Time duration (adjustable parameter), the room switches to Stand-by mode and Stand-by setpoints are used. While in Stand-by mode, if no motion is detected for the entire Unoccupied Time period (adjustable parameter), the room switches to Unoccupied mode and uses its Unoccupied setpoints. While in Stand-By or Unoccupied mode, any motion switches the room back to Occupied mode.
Typical Detection Pattern for PIR Lens

Recommended installation height for PIR sensor:
4 - 5 ft. / 1.2-1.5 m

APPENDIX D - VTR8300 CONTROLLER AND VC3000 RELAY PACK
Product Overview
The VTR8300 Fan Coil Controller offers a new cost-effective solution for upgrading line-voltage fan coil unit thermostats. The VTR8300 terminal Equipment Fan Coil Unit Controllers are available as BACnet® MSTP or wireless ZigBee® Pro networked models.
No previous building automation training is required for installation and commissioning process, and installation can be completed in approximately fifteen minutes.
The VC3000 Series Line Voltage Switching Transformer Relay Pack Controllers are designed for silent control of typical high voltage fan coil device loads (90 - 277 VAC multi-voltages). It uses advanced microprocessorbased circuitry with a built-in transformer that eliminates all typical required peripheral components when automating a Fan Coil unit with traditional building automation systems.
The VC3000 Series Line Voltage Switching Transformer Relay Pack(s) operate as slave unit(s) under the control of a single master VTR83XX Room Controller.
A single VTR8300 or VT8300 Room Controller can control up to 10 x VC3000 Series Relay Packs as they are line-powered units.
The unit locally contains all relay outputs for fan switching and valve control, and models are also available for extra monitoring/control inputs of the Fan Coil Units.

APPENDIX E - SED SERIES WIRELESS SENSORS
Wireless ZigBee® Pro Motion Sensors and Door/Window Switch
Wireless door switches used with an onboard or remote PIR sensor provide advanced local occupancy routines allowing for increased energy savings during occupied hours without sacrificing occupant comfort. Wireless window switches are used to monitor exterior windows or patio/balcony doors when opened to prevent unnecessary energy consumption. Fan Coil Room Controllers with SED Series ZigBee® Pro wireless switches can be used in stand-alone mode, or with integration to a central management system, to allow for advanced functions such as central reservation and occupancy functions. Up to twenty SED-WIN or SED-DOR ZigBee wireless switches can be used with a VTR8300 or VT8300 Room Controller Up to ten different ZigBee motion sensors and switches (SED-WMS, SED-CMS, or SED-WDS) can be used with a VTR8300 or VT8300 Room Controller Note that if a ZigBee wireless window switch is used, the VT8300 Room Controller cannot also use a remote PIR motion sensor, whether wired or wireless. Using one or more wireless remote PIR motion sensors means that a wired PIR motion sensor cannot be used, and vice versa. The SED Series sensors are factory delivered with batteries and are ready to be installed, configured, and used right out of the box. Due to the extremely small current consumption of the sensors, the expected battery life is approximately 10 years, which is equivalent to the battery shelf life. No tools are required for commissioning or servicing the ZigBee devices. A simple interface on the devices with an on-board LED and hidden switch provides all required functions for local interaction. The VT8300 user interface has screens used to pair and configure ZigBee devices (SED-WMS, SED-CMS, or SED-WDS only). Local information for battery life and connectivity (heartbeat) are also displayed through the ZigBee® Pro wireless network. For more information about using the SED-WIN and SED-DOR switches, consult the SED-WIN / SED-DOR Wireless Door and Window Switch Installation Guide. For more information about using the SED-WDS, SED-WMS and SED-CMS wireless switches and sensors, consult the Pairing VT8000 Series Room Controllers with ZigBee Sensors Installation Guide and Procedure.

APPENDIX F: TERMINAL CORRESPONDENCE
The terminals of an VT8300 are identified differently and have a wider range of possible functions compared to those of any of the VT7000 series Room Controllers. Nonetheless, there is a direct correspondence of functions between the terminals of the VT7000 series and the VT8300 series.
