Troubleshooting

It is recommended to wire the fan and the touchpad remote prior to turning on the power to the
fan. If the fan is not operable, but the touchpad remote is lighting up, cycle power to the fan.
If cycling the power did not resolve this issue, go to the fault code screen (reference page 47) and
check to see if there is a code present.
