Short version: can a Trane S8X1 continuous fan speed be increased from the lowest setting?

Hello all, I have recently had a new HVAC system installed. It is a Trane S8X1 single stage furnace and air handler, paired with an XR16 3 ton AC unit. The S8X1 blower has 9 speeds. Presently the settings for the cooling mode is speed 7 (C1.7), heating mode at speed 5 (H1.5), and continuous fan mode is set at the lowest speed (CF.1). The product data guide, and label on the inside panel indicate the air flow can be adjusted with the Menu/Option buttons. I am able to change fan speeds for heating and cooling modes, but not the continuous fan mode. I can only view it. Is this configuration change locked out? I would prefer the fan-only speed be higher. I am also waiting to hear back from my installer to see what they say.

Thanks in advance.

You are not alone with this request to change (increase) the Continuous Fan speed on this model.

Unfortunately it is set to the lowest fan speed by the manufacturer, and is not field adjustable, even by a tech.
