Connecting the CVTPRO Converter to a Controller with N2 Screw Terminals

To connect the CVTPRO converter to a controller with screw terminals (Figure 6):

1.Disconnect the three N2 wires from the controller screw terminals and temporarily isolate the individual bare wires with insulating tape.

2.Remove the 4-pin N2 socket from the CVTPRO N2 cable to expose the three wires (Figure 6 and Figure 7).

3.Connect the exposed N2+ (blue), N2- (white), and Ref (red) wires from the CVTPRO N2 cable to the controller screw terminals. Observe proper polarity.

4.Connect the 6-pin RJ11 phone plug on the opposite end of the CVTPRO N2 cable to the CVTPRO converter (Figure 3 and Figure 5).

To scan a N2 Bus:

1Disconnect the N2 Bus from the N2 master controller.

2Remove the N2 plug (with attached N2 wires) from the controller (4-pin plug on the VMA and 3-pin plug on other controllers).

3Connect the 3-pin or 4-pin N2 plug that was disconnected from the controller in Step 2, to the 4-pin N2 socket on the CVTPRO converter cable. (See Figure 7.) Observe proper polarity (N2+ is blue, N2- is white, Ref is red).

4Connect the 6-pin RJ11 phone plug on the opposite end of the CVTPRO N2 cable to the CVTPRO converter (Figure 3 and Figure 5).

Connecting the CVTPRO Converter to a Controller with a N2 Jack

To connect the CVTPRO converter to a controller with a removable N2 plug:

1.Remove the 3 or 4-pin N2 plug from the controller.

2.Plug the 3-pin plug CVTPRO N2 cable into the jack on the controller (The Variable Air Volume Modular Assembly [VMA] has 4-pin jack, and other N2 controllers have 3-pin jacks). Observe proper polarity (N2+ is blue, N2- is white, Ref is red).

3.Connect the 6-pin RJ11 phone plug on the opposite end of the CVTPRO N2 cable to the CVTPRO converter (Figure 3).

Note: Figure 7 shows the possible connections with a VMA controller with a removable 4-pin N2 plug.
