TROUBLESHOOTING

Please refer to the Troubleshooting Guide available on HVAC Partners for more detail.

Infinity Zone Control does not power up.

1. Recheck wiring to ABCD on all devices.
2. Make sure all colors match for every terminal.
3. Make sure power is applied to the indoor unit, and the amber LED is lit on indoor control circuit board.
4. Check for 24VAC between the C and D terminals at Infinity Zone Control terminal connector and Damper Control Module.
5. Check fuse on indoor unit’s circuit board.

Display says “Indoor Unit Not Found”

1. Recheck wiring to ABCD on all devices.
2. Make sure all colors match for every terminal.
3. Press left--side button to try again.
4. If display still reads “Indoor Unit Not Found”, disconnect accessories and all devices from ABCD and connect User Interface directly

to indoor unit with a short piece of thermostat wire. Add other devices one at a time to determine where the communication issue
exists.

Display says “Outdoor Unit Not Found”, and I have a two--stage communicating outdoor unit.

1. Recheck wiring to ABCD connector on outdoor unit.
2. Make sure all colors match for every terminal.
3. Check for 24VAC between the C and D terminal connector of outdoor unit.

I made a mistake on the start--up screens, and pressed the right--side button to get to the run mode. How do I get back to start--up?

1. Press the ADVANCED button for at least 10 seconds.
2. Install/Service menu will appear.
3. Scroll down to the INSTALL selection.
4. Press the right--side button; the screen will prompt you to press the right side again to re--install the system.

Control does not see zones 5 through 8.

1. Make sure zone module 5 -- 8 has the DIP switches set to the right.
2. Recheck wiring to the ABCD connectors.

Control says I have zones 5 -- 8 but not 1 -- 4.

1. Make sure zone module 1 -- 4 has the DIP switches set to the left.
2. Recheck wiring to the ABCD connectors.

Some zones in my zoned system do not provide enough comfort. (A noticeable difference exists between the actual room temperature
and operating setpoint, yet the equipment does not turn on).

1. The zone airflow limit may be set too low. Perform the Zone Airflow Limit Checkout procedure, raise airflow limit setting, if possible.

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, lower airflow limit setting if pos-

sible.

To check current system status.

1. Press the right side button. This will display the current active system faults.
2. If no faults are active, the Status screen will show status of each component in the system.
3. Pressing the right side button again will show the zone actual temperature and set temperatures. If the actual temperature is blinking,

this means it is calling for heating or cooling.
