Daikin Fit - high fan speed during purge

Post by mwheeler »

Hello,

I have a recently installed Daikin Fit system with the UT3000 and 3 zones. All zones are using Daikin One+ thermostats.

Everything is working well except that the fan speed during purge is annoyingly high.

The purge setting has been changed from 50% to 25%, but seemed to have minimal, if any, impact.

I see the UT3000 manual have several notes about purge speed, but to this point neither my installer or myself have been able to find a setting that notably reduces the purge fan speed.

My unscientific observation is that the fan speed seems to roughly equal the max fan speed I've experienced in high load situations, meaning it is far higher than I experience during normal runs.

Any assistance is appreciated.

I have the exact same system and also have the annoying Purge noise. Mine is also set at 25%, but seems like it's on full blast. Not sure how to solve this.
