TO RESET A FAULT CODE IF TRIGGERED.

1). Press the alam button.

2). press the down arrow to view faults.

3). Press the enter button twice to clear fault.

4) Press enter again to start. You should see a countdown in seconds on the display until the system turns on.

NOTE: Resetting a fault code only works if you've repaired the unit, or the fault has passed. If the fault does not clear there is a failure somewhere in the system. You may be able to still start in manual mode, but the staging of the compressors is done by its module board. The control is independent of the other modules and is based on the LCHW (water temp) of that module. When in Auto Mode the staging of the compressors is handled by the master controller. There is a large toggle switch labeled "Manual - Off - Auto" near the uper right of the Master Control. It is advised to contact tech support at Multistack before you proceed in manual mode. The number for Multistack is 608-366-2400.

See "Faults" starting on page 13 of the Multistack / Airstack APF User Manual listed below for more information on Fault codes.
