EFF
CMFRT
Introduced with AOC Software Version 2, Fall of 2014.
The drive uses multiple gates (micro relays) to run the
ID AIR HTG
compressor. These gates open and close very quickly. This
EFF
CMFRT
high frequency switching generates low levels of electromag-
netic interference that can interact with other devices in the
home; such as televisions, baby monitors, HAM radios, etc.
PFC
Changing the EMI setting from AUTO to OFF will alter the
ON
AUTO
switching frequency during higher speed compressor
operation which will alter the EMI signal.
EMI
Contact your local FSR if EMI is still impacting devices after
OFF
AUTO
switching EMI to OFF.
