It's manual. The positions in the 11 and 10 o'clock have the little snowflake and the switch positions in the 1 and 2 o'clock show only what I thought was vent. I know that all compressors cycle occasionally to keep the seal lubed but what happened to fresh air only? Am I missing something here? There is only a rotary switch. No button to push to activate the compressor.
Thanks,
