Question about Daikin FTXS18HVJU Wall Mounted Indoor Unit - 18000 BTU
When the Operation lamp is flashing, the unit can't operate efficiently and has shut off. Check and clean the Air Filters. Check that nothing is blocking the air inlet or outlets (on all indoor units (if a multi-unit system) and the outdoor unit). Remove all obstructions. Turn the breaker to Off and then On again. Check if the unit works with the remote.
If you have a multi-unit system, make sure that all indoor units are in the same Operation mode. If the units are on Auto, make sure that all units are set for Heat or Cool.
If the unit continues to have the Operation light flash, then you need to contact your service professional. The Operation manual for the FTXS18HVJU is available here: http://www.daikinac.com/content/assets/DOC/OperationManuals/FTXS15_18_24LVJU%20Operation%20Manual.pdf
I hope this helps.
