CAUTION:
IF VOLTAGE OTHER THAN 24VAC IS BEING SUPPLIED, USE APV-12-24 POWER SUPPLY INCLUDED WITH
FC-3T
240VAC installation
1. Find a suitable location for the APV-12-24. Secure the APV-12-24 with self-tapping screws
or double-sided tape.
2. Route the wires so that they will not short, abrade, or damage other components
3. Connect the FC-3 to the low voltage side of APV-12-24 (red and black wires) red to red and black to black.
a. Twist-on wire connectors (Figure 7) and crimp connectors (Figure 6) are both acceptable methods
of connecting low voltage wires.
4. Connect the high voltage side of APV-12-24 (blue and brown wires) to the terminal block where the 240v
wires enter HVAC unit.
5. Connect the orange wires to the Building Automation System wires or terminals (if present). If no BAS system
is present, then insulate ends of wires and secure wires where they will not be damaged.

ing low voltage wires. .
4. Connect the neutral leg of power to the blue wire. Connect the line or power leg to the brown wire
5. Connect the orange wires to the Building Automation System wires or terminals (if present). If no BAS system
is present, then insulate ends of wires and secure wires where they will not be damaged.
