Braemar spectrolink multizone fan speeds

Hi all,

I am wondering if there is anyway to manually adjust the fan speeds on these models? I have 2 SCC and the manual says it cant be done, are there any options which will allow me to do this? Last time I was here I was helped with my other homes unit and am wondering if there is anything similar that can be done ( changed some codes via the control unit) The fans really ramp up and are quite noisy but really do push out alot of heat/cold.

Is this how these systems work? To automatically go to the highest fan speed to cool/heat up the home as quickly as possible then shut off?

Cheers.
