Attribute

VAV1xx

FX-PCG

Implication

I/O Wiring

Connection Location

See Figure 1.

See Figure 1.

You can reuse the existing I/O wiring if the existing wiring is long enough to reach the FX-PCG's I/O wiring connection points. If not, you need to lengthen the wiring.

Connection Type

Spade lug connectors

Fixed screw terminal connectors

Remove spade lug connectors from I/O wiring.

N2 Wiring

Connection Location

See Figure 1.

See Figure 1.

You can reuse the existing N2 wiring if the existing wiring is long enough to reach the FX-PCG's N2 connection point. If not, you need to lengthen the wiring.

Connection Type

Removable, 3-wire screw terminal connector

Removable, 4-wire screw terminal connector

Replace the UNT's N2 wiring connector with the FX-PCG's N2 connection point.

Power Supply Wiring

Connection Location

See Figure 1.

See Figure 1.

You can reuse the existing power supply wiring if the existing wiring is long enough to reach the FX-PCG's power supply connection point. If not, you need to lengthen the wiring.

Connection Type

Spade lug with removable 2-wire screw terminal connector
