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)
