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.

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.

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
closed.
On Call for Heat
Heating valve opens to maintain room temperature. Cooling valve
closed.
Wireless Door Switch and Motion
Wireless door switch automatically toggles occupancy to standby.
Motion will switch to occupied as long as the door stays closed
Options
• Wireless adapter modules are available. (see Appendix B for
network wiring).
• Can be configured for 2-pipe systems (without changeover).
• Binary inputs can be configured to control occupancy via
door or window contact, remote motion sensor, or remote
night setback.
3 Speed Fan Operation
System Off
Brown, blue and red wires are not energized
System On: (Fan modes)
• Low: red wire is energized
• Med: blue wire is energized
• High: brown wire is energized.
• Auto: When there is no demand, brown, blue and red wires
are not energized. On demand, system will automatically

On Call for Cool
Cooling valve opens to maintain room temperature.
On Call for Heat
Electric heat operates to maintain room temperature. Cooling valve closes and dehumidification is disabled.
On a Demand for Dehumidification
Dehumidification achieved via cooling coil using 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.
