Relay Pack
A compact and easy to install Relay Pack for line-voltage fan coil units to be used in combination with room controllers. The
VC3000 is a Relay Pack for line-voltage fan coil units. The device is used with VTR7300 and VTR8300 room controllers as
a two component retrot option.
Features
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.
No previous building automation training is required for the installation and
commissioning process.
Existing line voltage wiring between the fan coil unit and temperature
Controller can be reused further minimizing overall labor and installation costs.
