FC-1T-1VDC user manual
The FC-1T-1VDC has a 0 to 10 VDC signal output and a disconnect relay that allows you to easily and effectively
control up to 10 variable frequency drives, slave units, modulating valves, or other equipment that requires a DC
signal.
The knob allows you to easily move between and adjust settings, while the programming lights show which settings
you are editing. The two LED displays show temperatures, signal output, programming information, and alarm
codes.
Features
Temperature-based control with extended range:
−13 to 125°F (−25 to 51°C)
Variable 0 to 10 V output
Capacity for up to 10 devices
Disconnect relay for start/stop signal
Alarm relay (for external alarm system or siren)
3-second full-power-turn-on to minimize fan ice-up
Status and programming LEDs
Installation
Switch OFF the power at the source before connecting the
incoming power wires.
DO NOT switch on the power until you have finished all
wiring and verified all equipment is properly connected and
free of obstructions.
