Hi. I just had a mini split AC system installed. One outdoor unit with 4 indoo r units. When I turn one indoor unit on to cool the room, I notice that th e other 3 (in 3 different rooms) also get cold (though their fans are not o n). Just curious: don't each of these operate like zone valves? Seems was teful to pump refrigerant through all when only some are "on". Interested to learn, Theodore.
