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.

* Wired remote sensor cannot be used at the same time as wireless remote sensor(s).
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.
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.
Options
•Wireless adapter modules for BACnet models are available.
(see Appendix B for network wiring).
•Remote wall mount or return duct sensor ready.
•Can be configured for 2-pipe systems with changeover.
•Binary inputs can be configured to control occupancy via
door or window contact, remote motion sensor, remote night
setback, or provide alarms for service or filter monitoring.
•Universal input can be configured for changeover sensor.
