Fan speed vs auto

Hello,

We have a heat pump with electrical resistance aux.

I’ve seen people recommend setting the fan so it runs continuously vs using the auto function.

If I set the fan speed to run at “low” continuously, will it kick into high speed when needed or when the aux comes on? Or does it in fact, remain at low speed 24/7?

We have a bungalow with a finished basement. South facing. Lots of daytime sun and windows.

Wondering if I should set to low/med or leave it on auto?

Stat is a Carrier infinity. Approx 10 yrs old.

As an example..... most of the main floor is 25c today due to the sun. Outside temp is -1c.
Basement is 18c. North facing bedrooms are 20c. Stat is set for 22. I’d assume using low will provide some greater consistency.

There are pros and cons for fan running continuously. It has been discussed in other threads.
Try it for yourself.

The heat will increase the blower speed.
