TROUBLESHOOTING
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 all
devices from ABCD and connect User Interface directly to
indoor unit.
Display says "Outdoor Unit Not Found", and I have a two-
speed 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 hit 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 set point, 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 possible.
