VTR8300 Fan Coil ControllerApplication Guide

OVERVIEW

VTR8300 & Relay Pack

This new cost-effective solution for upgrading line-voltage fan coil unit thermostats requires only two components: the VTR8300 terminal equipment controller and the SC3000 relay pack. This solution allows existing line voltage wiring between the fan coil unit and temperature controller to be re-used, reducing overall costs and installation time. The SC3000 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 VTR8300 Line Voltage Fan Coil Terminal Equipment Controller and SC3000 Relay Pack can be conﬁgured to handle a broad variety of applications covering all the standard implementations necessary for controlling line-voltage HVAC systems.

In addition to controlling heating, cooling and fan activity, depending on the model the VTR8300 can handle wireless networking and switches, passive infrared (PIR) occupancy detection using either onboard or remote sensors, and dehumidiﬁcation control. The applications described here cover all these features, and in combination with the VTR8300’s advanced scheduling and occupancy controls can provide the functionality for any required line-voltage HVAC implementation.

VTR8300 Fan Coil ControllerApplication Guide

APPENDIX A - PASSIVE INFRA-RED (PIR) MOTION DETECTOR COVER SPECIFICATIONS

PIR cover sequence of operation

Initially, the controller is in Stand-by mode. Stand-by setpoints are used at the controller. As soon as the PIR detects motion, the Occupancy status switches to Occupied and the Stand-By Time timer is reset. The Occupied setpoints are used. If no motion is detected in the room for the entire Stand-By Time duration (adjustable parameter), the room then 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 will switch 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

Sensor Ranges

A = 20 ft. / 6.1 m B = 14 ft. / 4.3 m C = 11 ft. / 3.4 m

APPENDIX D - SED SERIES - WIRELESS DOOR & WINDOW SWITCH

®

Wireless ZigBee

Wireless door switches used with an onbaord 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 and or patio and balcony doors being opened or closed. This prevents unnecessary energy consumption by the tenants.

Fan Coil Terminal Equipment Controllers with SED Series ZigBee network ready mode with or without integration to a central management system to allow for advanced functions such as central reservation and occupancy functions.

A combination of up to twenty SED Series door and or window switches can be used simultaneously with a single Fan Coil Terminal Equipment Controller.

The SED Series switches are factory delivered with 2 AAA batteries and are ready to be installed, conﬁgured and used right out of the box. Due to the extremely small current consumption of the switches, the expected battery life is approximately 10 years and is equivalent to the battery shelf life.

No tools are required for commissioning or servicing the door switch. A very simple interface with an onboard LED & hidden switch provides all the required functions for local interaction. Local information for battery life and connectivity (heartbeat) are provided at the Fan Coil Terminal Equipment Controller local display through the ZigBee security tamper proof screw and self tapping mounting screws.

APPENDIX E - VTR8300 CONTROLLER & SC3000 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 wireless ZigBee

®

Pro networked models.

No previous building automation training is required for the easy installation and commissioning process. Installation can be completed in approximately ﬁfteen minutes, reducing costs and providing increased savings.

The SC3000 Series Line Voltage Switching Transformer Relay Pack Controllers has been designed for silent control of typical high voltage fan coil device loads (90 to 277 VAC multi-voltages capable).

It uses advanced microprocessor-based 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 SC3000 Series Line Voltage Switching Transformer Relay Pack(s) operate as slave unit(s) under the control of a single master VTR8300 Terminal Equipment Controller.

A single VTR8300 Terminal Equipment Controller can control up to 10x SC3000 Series Relay Pack. The SC3000 Series Relay Packs are line-powered units.

The extremely compact unit locally contains all the relay outputs for fan switching and valve control. Models are also available for extra monitoring / control inputs of the Fan Coil Units.
