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.

APPENDIX A TERMINAL CORRESPONDENCE
The terminals of a VT8300 are identified differently and have a wider range of possible functions compared to those of any of the
VT7300 series Room Controllers. Nonetheless, there is a direct correspondence of functions between the terminals of the VT7300
series and the VT8300 series. Consult the table below to verify the appropriate terminal when replacing a VT7300 Room
Controller with a VT8300 Room Controller.
VT7300 VT8300
Terminal name Terminal ID Terminal name Terminal ID
Binary Input 1 BI1 Universal Input 16 UI16
Binary Input 2 BI2 Universal Input 17 UI17
Universal Input 3 UI3 Universal Input 19 UI19
Sensor Common Scom Terminal 18 Common COM
Remote Sensor RS Universal Input 20 UI20 - RS
Sensor Common Scom Terminal 21 Common COM
Mix/Supply Sensor MS Universal Input 22 UI22 - SS
APPENDIX B POWER OUTAGE CLOCK RESET
In the event of a power outage, VT8300 Room Controllers retain the correct time as long as the duration of the power outage is
not prolonged. Depending on the duration of the power outage, the Room Controllers internal clock may need to be updated or
reset completely. The following table gives an indication of the expected clock performance after a power outage.
Outage duration Room Controller behaviour
0 - 24 hours Clock functions are normal
24 - 36 hours Clock accuracy not guaranteed, time may need to be adjusted
36 - 72 hours Clock no longer increments and must adjusted when power is
restored
72+ hours Clock functions are fully reset, and must be reinitialized as per a new
installation
