SETTING STATIC PRESSURE OR 
AUTOMATIC AIRFLOW WHEN USING THE 
RG57 WIRELESS CONTROLLER:
The external static pressure should be selected using the wireless 
remote controller (RG57F3(B)/BGEFU1), included with the indoor 
unit, by pointing it toward the indoor unit’s Infrared Receiver 
typically located inside the control box.
1. Before using the service functions of the remote, turn OFF the
indoor unit with the remote.
2. Turn off the power to the indoor and outdoor units for 3 minutes.
Turn the power back on.
3. Remove the batteries from the RG57 remote and wait for the
remote screen to clear or press any button and the screen will clear.
4. Reinstall the batteries.
5. Within 30 seconds of replacing the batteries, simultaneously press
MODE and TIMER ON for five (5) seconds. You are now in the
SERVICE FUNCTION mode – and the remote display reads F1.
6. Press the DOWN arrow in the center of the remote (labeled
TEMP) to display E9.
7. Press        or       to select E9.
8. Press  MODE to set the airflow rate in the range of 1~4 (airflow
increases quickly).
9. Press TIMER ON to confirm.
10. Remove the remote controller battery, and then re-insert the battery
after the remote controller screen goes blank. The remote controller
exits the MODIFICATION mode. After you power OFF the unit,
power the unit ON again and the unit retains the setting value.
