I got my RD3 all put together last night and have been combing the forum for tips on these items and could use some additional guidance, please.
With the RD3 on a table and a TC connected as the pit probe:
1) My fan is running non stop. I have all of the fan output values listed at 0%. The probe is reading room temp, the set point is 20 degrees below that. When the auto fan mode is disabled, I can control the servo. If I leave it open, then enable auto fan mode, it closes fully, so that seems to be working. Initially, the graph shows that the fan is at 100% and then after a few minutes it shows fan at 0% but it is clearly still running. What am I missing here with the fan?
2)Servo is fully closed when it shows 20% or less and is not quite fully open at 100%. I have been tinkering with the outside damper plate and the servo pulse duration settings to try to get it right. I'm still working through it, but is this pretty standard to work out the kinks and get it right or did I mess something up from the beginning in putting the servo and the damper plate together?
3)Ultimately, I want to get the servo and fan functioning where the fan only kicks on after the servo has been fully opened and the set temp is not yet achieved. I followed this for the firmware I am running and no longer see the "On at Max only" option that I had before.
"To install the snapshot firmware, just go to System -> Backup / Flash Firmware and put the snapshot url in the "Image URL (.gz)" box. This will also update your HeaterMeter's AVR Firmware to the snapshot as well.

Thanks!
