Zoning User Interface Control does not power up:

1.Recheck wiring to ABCD on all devices. Make sure all colors match for every terminal.

2.Make sure power is applied to the indoor unit, and the Yellow and Green LEDs are lit on the Infinity Damper Control.

3.Check for 24 VAC between the C and D terminals at the User Interface terminal block.

4.Check fuse at indoor unit circuit board and Infinity Damper Control.

Zoning User Interface Display says, ″Indoor Unit Not Found″:

1.Recheck wiring to ABCD on all devices. Make sure all colors match for every terminal.

2.Press side button at User interface to try again.

3.Check power to indoor unit.

4.Disconnect all ABCD connections from every device and only reconnect the User Interface to the indoor unit. If the indoor unit is identified by the User Interface, then another device on the ABCD connection may be at fault. Reconnect each device’s ABCD connection one at a time and perform a Re-Install from the Service Menu after each connection is made. If one or more devices are not found after reconnecting the last device, the last device may be suspect.

5.If the ABCD connection only contains an indoor unit and a User Interface, then the wiring, indoor unit control board, or User Interface may be at fault.

Zoning User Interface Display says, ″Outdoor Unit Not Found″, when applied with a two-speed communicating out- door unit:

1.Recheck wiring to ABCD connector on outdoor unit. Make sure all colors match for every terminal.

Zoning User Interface cannot find Zones 5 through 8:

1.Make sure zone module 5 - 8 has the dip switches set to the far right.

2.Recheck wiring to the ABCD connections.

Zoning User Interface can find zones 5 - 8 but not 1 - 4:

1.Make sure zone module 1 - 4 has the dip switches set to the far left.

2.Recheck wiring to the ABCD connections.

Some zones do not provide enough comfort (a noticeable difference exists between the actual room temperature and operating set point or equipment does not turn on)

1.The zone airflow limit may be set too low. Perform the zone airflow limit checkout procedure. See Infinity Zoning System User Interface installation instructions for details.

Some zones provide too much airflow and are noisy:

1.The zone airflow limit may be set too high. Perform the zone airflow limit checkout procedure. See Infinity Zoning System User Interface installation instructions for details.

Zone dampers do not move:

1.Check fuse located on Infinity Damper Control. If fuse failed, check damper wiring and inspect for shorts. No more than five damper motors should be connected to a single damper output. Fuse should be replaced with an identical 3 amp automotive fuse.
