Review on White Senville Dual Zone Mini Split Air Conditioner Heat Pump, 28000 BTU, Alexa Compatible - SENA-30HF/D by Steve Stone

I bought the 3-zone mini split and it is quieter than my air purifier. It works really well and is very efficient. Like another reviewer I noticed it changed the display to two dashes on all units at one time. My office window was open and the mode was set to auto, so once the air temp went below the temp setting on the cassette it tried to turn on the heat for that unit. Apparently you cannot run heat on one unit and cool on the others so it shut down the system. Changing all modes to cool instead of auto resolved the issue for me.Overall I am extremely happy with this system!
