VT8300 Series Installation Guide 24 Vac Low Voltage Commercial and Hotel/Lodging HVAC Fan Coil Applications for 1, 2, 3-speed or ECM motors• If replacing an existing Room Controller, label wires before removal of Controller. • Electronic controls are static sensitive devices. Discharge yourself correctly before manipulating and installing Room Controller. • A short circuit or wrong wiring may permanently damage Room Controller or equipment. • All Room Controllers are designed for use as operating controls only and are not safety devices. Tampering with the devices or unintended application of the devices will result in a void of warranty. • This device must be installed to provide a separation distance of at least 8in (20cm) from all persons and must not be located or operating in conjunction with any other antenna or transmitter. CLEANING THE ROOM CONTROLLER • Use a soft, pre-moistened lint-free cloth for cleaning. • Avoid getting moisture in openings. • Do not spray anything directly on the Room Controller or use compressed air. • Do not use caustic/corrosive products, ammonia, solvents or any cleaning product containing alcohol or grit. • Never use tools directly on the touchscreen. • Never use paint on the Room Controller. • Do not drop or crush the Room Controller, or allow it to come into contact with liquids. • Do not use a damaged device (such as one with a cracked screen). • Performance can be affected if the glass on the screen is broken. Failure to comply with these recommendations will result in damage to the unit and void the manufacturer’s warranty. LOCATION • Do not install on outside wall. • Do not install behind a door. • Do not install in areas with direct heat source. • Do not install near any air discharge grill. • Do not install in areas exposed to direct sunlight. • Ensure Room Controller has sufficient natural air circulation. • Ensure wall surface is flat and clean. • Ensure external thermal sensor wirings are away from noisy electrical sources. • Install 1.3 to 1.5 meter (52 to 60 inches) above the floor.3 Viconics Technologies Inc. www.viconics.com sales@viconics.com 028-0429-05 November 2018 Figure 1 Open the cover Figure 2 Install the base Figure 3 Reinstall cover INSTALLATION Installation 1. Remove security screw (if any) on bottom of Room Controller cover. 2. Open unit by pulling on bottom side of Room Controller (Figure 1). 3. Read FCC ID and IC label installed in cover before installing any wireless product. 4. Ensure correct side of base faces up. 5. Pull cables 6in (15cm) out from wall. 6. Align base and mark location of two mounting holes on wall (Figure 2). 7. Install anchors in wall. 8. Insert cable in central hole of base. 9. Insert screws in mounting holes on each side of base. 10. Strip each wire 1/4in (0.6cm) from end. 11. Insert each wire and screw according to wiring chart (see following pages). 12. Gently push excess wiring back into hole. 13. Gently align cover to top of base and snap in place from bottom (Figure 3). 14. Install security screw.4 Viconics Technologies Inc. www.viconics.com sales@viconics.com 028-0429-05 November 2018 Fan Type - 3-Speed Control TypeOn/OffFloatingAnalog 1- BO1 Not usedNot usedNot used 2- BO2Fan-LFan-LFan-L 3- BO3Fan-MFan-MFan-M 4- BO4Fan-HFan-HFan-H 5- RC / 24 V~ Hot24 V~ Hot24 V~ Hot24 V~ Hot 6- C / 24 V~ Com 24 V~ Com24 V~ Com24 V~ Com 7- RH Aux HeatAux HeatAux Heat 8- BO8Aux HeatAux HeatAux Heat 9- UO9Normally Close Cool ValveClose Cool ValveNot used 10- UO10Normally Close Heat ValveClose Heat ValveNot used 11- UO11 Normally Open Cool ValveOpen Cool ValveAnalog Heat Valve 12- UO12Normally Open Heat ValveOpen Heat ValveAnalog Cool Valve 13- RS485 + RS485 + 14- RS485 -RS485 - 15- RS485 RefRS485 Ref 16- UI16UI16 Function 17- UI17UI17 Function 18- Scom Common 19- UI19UI19 Function 20- UI20Remote Room Sensor 21- ScomCommon 22- UI22Remote Supply Sensor 23- UI23 Not used 24- UI24Not used TERMINAL IDENTIFICATION AND FUNCTION Terminal identification for 3-Speed Fan System5 Viconics Technologies Inc. www.viconics.com sales@viconics.com 028-0429-05 November 2018 Terminal identification for ECM Fan System Fan Type - ECM Control Type On/OffFloatingAnalog 1- BO1 Normally Close Heat ValveClose Heat valveNot used 2- BO2Not usedNot usedNot used 3- BO3Not usedNot usedNot used 4- BO4ECM Fan StartECM Fan StartECM Fan Start 5- RC / 24 V~ Hot24 V~ Hot24 V~ Hot24 V~ Hot 6- C / 24 V~ Com 24 V~ Com24 V~ Com24 V~ Com 7- RH Aux HeatAux HeatAux Heat 8- BO8Aux HeatAux HeatAux Heat 9- UO9Normally Close Cool ValveClose Cool ValveNot used 10- UO10Analog ECM FanAnalog ECM FanAnalog ECM Fan 11- UO11 Normally Open Cool ValveOpen Cool ValveAnalog Heat valve 12- UO12Normally Open Heat ValveOpen Heat ValveAnalog Cool Valve 13- RS485 + RS485 + 14- RS485 -RS485 - 15- RS485 RefRS485 Ref 16- UI16UI16 Function 17- UI17UI17 Function 18- Scom Common 19- UI19UI19 Function 20- UI20Remote Room Sensor 21- ScomCommon 22- UI22Remote Supply Sensor 23- UI23 Not used 24- UI24Not used6 Viconics Technologies Inc. www.viconics.com sales@viconics.com 028-0429-05 November 2018 Wiring - Single or Multispeed Motor Power and Fan HIGHHIGH MED LOWLOW HIGHHIGHHIGH MED LOWLOW HIGH 3 Speed2 SpeedSingle Speed 24 Vac Transformer RC (24 Vac) C (Common) RH BO8 - Aux Heat R RC (24 Vac) C (Common) RH BO8 - Aux Heat R BO8 Auxiliary Output Wiring Dry contact to end device 24 V~ maximum24 Vac power to relay Power and Fan Relay Coil Wiring ECM Motor BO4 - Fan H RC (24 Vac) C (Common) UO10 ECM Fan Transformer 24Vac 0 - 10Vdc signal 24Vac signal to start fan (optional) 4 + -7 Viconics Technologies Inc. www.viconics.com sales@viconics.com 028-0429-05 November 2018 Main Outputs Wiring 2 Pipe Applications4 Pipe Applications Control type = On-Off OR Heating / Cooling valve Com 24Vac UO9 UO11 Heating valve Cooling valve OR OR UO10 NC UO12 NO UO09 NC UO11 NO Com 24Vac Com 24Vac Floating control Heating / Cooling valve UO11 UO9 Com Open Close Heating valve Cooling valve UO12 UO10 UO11 UO9 Com Open Close Com Open Close Analog control Heating / Cooling valve UO12 Com 24Vac 0-10Vdc Heating valve Cooling valve UO11 UO12 Com 24 Vac 0-10 Vdc Com 24 Vac 0-10 Vdc8 Viconics Technologies Inc. www.viconics.com sales@viconics.com 028-0429-05 November 2018 REMOTE SENSOR ACCESSORIES Model no.Description S3010W1031Wall mounted temperature sensor S3020W1031Wall mounted temperature sensor with override button and occupancy status LED The VT8300 Room Controller is compatible with remote mount temperature sensors using 10K type 2 NTC thermistors.
