So what I want: I want the heat pump to turn on when the temperature in the room reaches a certain point, and to turn off when it reaches a certain point.

Example: when the temperature of the room falls below 19°C, the heat pump powers on. When the temperature reaches 23°C , it turns off.

I have purchased a mysa, but it only seems to follow timed schedules where it sets the head to a certain level, and the head will then disperse air at that temperature indefinitely.

It’s the same if I use the remote to set the head to, as an example, 22 °C. It just keeps blowing at that temp until I turn it off. The room will end up getting too warm.

Are they meant to stay on and blowing all the time? It doesn’t seem necessary.

Additional info: Lennox heat pump. Dual heads. (Minisplits)

I have google home set up

I have a mysa thermostat

There is no thermostat for the heat pump, only the infrared remote (and now a mysa)

    They are meant to be blowing all the time. They gain efficiency by constantly putting out a little bit of heat not big on/off swings.

    You seem to be working on the assumption that max on is the most efficient this is not typicaly the case https://www.solutionsforair.com/dayton_content/pdfs/FanCurves.pdf fan designs have optimal ranges on high is not typicaly optimal air moved vs energy expended.

    Heat pumps a do not get as hot as traditional heaters so high airflow makes humans feel cold. If it’s just putting out air a bit above your body temp then blowing it hard on you it’s not pleasant and warm rather feels a bit chilly but it will warm the room to the setpoint.

    Defrost if you run the unit flat out the exterior quickly drops below dewpoint and freezing point so you have to defrost it, this wastes energy. A necessary evil at times but you want to minimize this. Running constantly means your keeping air moving over the coils helping to keep moisture from collecting, your temps won’t be as low so your not below freezing as often.

    You could turn the heat function on/off at those set points via automation but frankly you’re not doing your wallet or comfort any favors by doing so. Perfect world the unit is running 24/7 and putting out just enough heat to deal with losses.
