Explanation for Fan Control parameters, please (FK8)
Posted: Tue Aug 20, 2019 5:21 pm
Hi - I couldn't find any explanation for the Fan Control parameters. Can you please confirm/update my understanding?
Given what is displayed in the attached pic (FK8 base maps):
- Fan turns on at low speed at 'Hysterisis Threshold Lo' of 189F; at 'Low/High Control Lo' of 181F it turns off after the 'Fan Afterrun Time' of 90 seconds?
- Fan turns on high speed at 'Hysterisis Threshold Hi' of 199F; at 'Low/High Control Hi' of 189F it either:
a) turns off after the 'Fan Afterrun Time' of 90 seconds if the temperature is below the 'Hysterisis Threshold Lo' of 189F; or
b) switches to low speed if the temp if the temperature is above the 'Hysterisis Threshold Lo' of 189F (and below the 'Hysterisis Threshold Hi' of 199F)?
- Is 'Fan Afterrun Time' independent of motor on/off, key on/off, etc.?
- Is ECT or ECT2 used? As an aside, where are these sensors?
- What is max value of 'Fan Afterrun Time, please?'
